2. Mr. Jansen needs to order picture frames for his paintings. He has $4,000 to buy 98 frames priced at $42 each. Mr. Jansen says he has enough money because 100x40=4,000. Is his reasoning corrector not? Explain your reasoning.
Answer:
The reasoning isn't correct
Step-by-step explanation:
This is becuase the given amount for each frame is 42 dollars not 40 like it is listed in the equation. Another reason the reasoning from Jansen is wrong is because he wants to buy 98 frames, not 100 like it was listed in the equation.

A bus makes a stop 2:30 letting off 13 people and lettng on 8. The bus makes another stop ten minutes later to let off 3 more people. How does the number of people on the bus after the second stol compare to the number pf people on the bus before the 2:30 stop??
Answer:
The number of people on the bus after the second stop is 8 less than the number of peoples on the bus before the 2:30 stop.
Step-by-step explanation:
Let [tex]P_0[/tex] be the total number of peoples on the bus before 2:30 stop.
For the first stop at 2:30:
The bus let off 13 people, so, the total number of remaining people on the bus [tex]= P_0-13[/tex]
again, the bus let on 8 people, so, the total number of people on the bus
[tex]= P_0-13+8[/tex]
[tex]=P_0-5[/tex]
For the second stop after 10 minutes (i.e at 2:40):
The bus let off 3 people, so, the total number of remaining people on the bus [tex]= P_0-5-3[/tex]
[tex]=P_0-8[/tex]
After the second stop, the number of people on the bus is [tex]P_0-8[/tex], where P_0 number of peoples on the bus before 2:30 stop.
Hence, the number of people on the bus after the second stop is 8 less than the number of peoples on the bus before the 2:30 stop.

C) y=4x+1
Step-by-step explanation:
y=4x+1
Answer:
option c) y = 4x + 1
Step-by-step explanation:
(-1 , -3) ; (2 , 9)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]= \frac{9-[-3}{2-[-1]}\\\\=\frac{9+3}{2+1}\\\\=\frac{12}{3}\\\\= 4[/tex]
Equation : y - y₁ = m(x - x₁)

Answer: 490
Step-by-step explanation:
Which of the following equations have no solution? Check all that apply.
6x + 1 = 3(2x – 4)
2 – 5x = 7x – 12
4(3 – x) = 2(6 – 2x)
5(x + 2) = 2(x – 4)
–4(x + 3) = 4(–x – 1)
Answer:
–4(x + 3) = 4(–x – 1) and 6x + 1 = 3(2x – 4)
Step-by-step explanation:
Answer:
1 ans 5
Step-by-step explanation:
no solution –––
6x + 1 = 3(2x - 4)
6x + 1 = 6x - 4
6x - 6x + 1 = 6x - 6x - 4
1 ≠ -4
one solution
2 - 5x = 7x - 12
2 -5x + 5x = 7x + 5x - 12
2 = 12x - 12
2 + 12 = 12x - 12 + 12
14 = 12x
x = 14/12
infinite solutions
4(3 - x) = 2(6 - 2x)
12 - 4x = 12 - 4x
12 - 12 - 4x + 4x = 12 - 12 - 4x + 4x
0 + 0 = 0 + 0
0 = 0
one solution
5(x + 2) = 2(x - 4)
5x + 10 = 2x - 8
5x - 5x + 10 + 8 = 2x - 5x - 8 + 8
18 = -3x
x = -6
no solution –––
-4(x + 3) = 4(-x - 1)
-4x + 4x - 12 = -4x + 4x - 4
-12 ≠ -4

Bradley went on a bike ride to the store 6 miles away. If it took Bradley 38 of an hour to get there and 14 of an hour to get back, what was his average rate of speed (miles per hour) for the entire trip? (Hint: To find the average, divide the total distance by the total duration.)
Answer:
19.2
Step-by-step explanation:
The average speed for the entire trip was 0.23 miles per hour.
What is average speed?The average speed is the total distance travelled by the total time taken to travel the distance. It does not depend upon the instantaneous speed of the object.
The total distance of the store is 6 miles.
The time taken to reach is 38 hour.
And, the time to come back is 14 hours.
Since, the average speed is given as the ratio of the total distance to the total time.
Here, the total distance is 2 times the given distance.
Thus, the average speed is found as.
(6 + 6)/ (14 + 38)
= 12/52
= 3/13
= 0.23
Hence, the average rate of speed for the entire trip is 0.23 miles per hour.

Guadalupe fue a la mercería a comprar 15.5 m de encaje blanco que necesita para la clase de costura. Si cada metro cuesta $5.60, ¿cuánto pagó por todo el encaje que necesita?
También pidió 4.75 m de cinta azul que le encargó su mamá. Si el metro cuesta $8.80 y su mamá le dio $40.00, ¿le alcanzará el dinero para comprarla?
¿Le falta o le sobra dinero? ¿Cuánto?
Answer:
a) Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.
b) Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.
Step-by-step explanation:
a) Tras una lectura cuidadosa al enunciado, establecemos que el coste total pagado por Guadalupe es el producto de metraje comprado ([tex]n[/tex]), medido en metros, y el coste unitario ([tex]c[/tex]), medido en pesos por metro:
[tex]C = c\cdot n[/tex] (Eq. 1)
Si conocemos que [tex]c = 5.60\,\frac{\$}{m}[/tex] y [tex]n = 15.5\,m[/tex], entonces tenemos que:
[tex]C = \left(5.60\,\frac{\$}{m}\right)\cdot (15.5\,m)[/tex]
[tex]C = \$ \,86.8[/tex]
Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.
b) El coste total de la cinta azul es: ([tex]c = 8.80\,\frac{\$}{m}[/tex], [tex]n = 4.75\,m[/tex])
[tex]C = \left(8.80\,\frac{\$}{m} \right)\cdot (4.75\,m)[/tex]
[tex]C = \$\,41.8[/tex]
Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.

x equals one
3/2+1/2x=2x
3/2+1/2=2x
2=2x
1=x
Answer:
2 = x
Step-by-step explanation:
3/2 + 1/2 times x = 2x
x by itself = 1x
Subtract 1x
3/2 + 1/2 times 1x - 1x = 2x -1x =
3/2 + 1/2 = 1x
3/2 + 1/2 = 4/2 = 2
2 = 1x
1x/1 = x
2/1 = 2
2 = x

Remember, the values of both variables may change in an experiment and are recorded. The difference is that the value of the independent variable is controlled by the experimenter, while the value of the dependent variable only changes in response to the independent variable
Step-by-step explanation:
Answer:
The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Step-by-step explanation:
Macon Steinberg purchased a motor scooter with an installment loan that has an APR of 16 percent. The motor scooter sells for $1,687. The store financing requires a 20 percent down payment and 30 monthly payments.
What is the down payment?
What is the amount of the loan?
What is the monthly payment?
What is the total amount repaid?
What is the finance charge?
The finance charge is $285
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Given;
An installment loan that has an APR of 16 percent
The motor scooter sells for $1,687
The store financing requires a 20 percent down payment
Monthly payments are for 30months
Now,
Downpayment= cost of scooter*20%
=1687*20%
=$337.4
Amount of finance = Cost of scooter - Down payment
=1687-337.4=1349.6
Interest rate=16%*1/12=1.3% per month
Monthly payment = Amount of finance*I/[1-(1+I)^-n]
=1349.6*1.3%/[1-(1+1.3%)^-30]
=1349.6*0.013(1-0.6780)
=17.5448/0.322
=54.486
Total amount paying for loan over a period = Monthly payment * Term
=54.486*30=1634.6
Amount of finance charge = Total amount paying for loan - Amount of loan
Amount of finance charge =1634.6-1349.6
=285
Therefore, the finance charge by given percent will be $285

How many quarts of water must be added to 7 qts of a 19% saline solution to obtain a 5% saline solution?
Answer: quantity of water added = 19.6 quarts
Step-by-step explanation:
Let x= quantity of water added
Then, Quantity of saline in 7 quarts solution = 19% of 7 = 0.19 (7)=1.33 quarts [to remove % divide number by 100]
When x quarts water is added , the quantity of solution becomes = x+7
Quantity of saline in it= 5% of (x+7)= 0.05(x+7)
Now, quantity of saline remains same, so
[tex]1.33= 0.05(x+7)\\\\\Rightarrow\ 1.33x=0.05x+0.35\\\\\Rightarrow\ 1.33-0.35=0.05x\\\\\Rightarrow\ x=\dfrac{0.98}{0.05}=19.6[/tex]
Hence, quantity of water added = 19.6 quarts

Answer:
B, C, D, E, A
Step-by-step explanation:
In order to know you have to get them all to the same form. This means converting all of them to a fraction or decimal. You can convert to whichever you prefer. I will be doing decimals since I find that easiest to understand.
A = 13.5
B = -13.5
C = -3
D = 0
E = 0.135
You can see then that the order is B, C, D, E, A.
