Answer:
4 more pens
Step-by-step explanation:
Well, what do we know?
We know Sheila has:
6 pens
10 pencils
How many MORE pens does she need to make the number of pens equal to the number of pencils?
6 + x (x is the number of pens needed to EQUAL to 10)
6 + x = 10
x = 4
Sanity check:
6 + 4 = 10
Sheila needs 4 more pens to make the number of pens and pencils equivalent, or EQUAL TO each other.

Step 1: Define Systems
5x + y = 9
10x - 7y = -8
Step 2: Rewrite Systems
Manipulating: Equation 5x + y = 9
Subtract 5x on both sides: y = 9 - 5xStep 3: Redefine Systems
y = 9 - 5x
10x - 7y = -8
Step 4: Solve for x
Substitution
Substitute in x: 10x - 7(9 - 5x) = -8Distribute -7: 10x - 63 + 35x = -8Combine like terms: 45x - 63 = -8Add 63 on both sides: 45x = 55Divide 45 on both sides: x = 11/9Step 5: Solve for y
Define equation: 5x + y = 9Substitute in x: 5(11/9) + y = 9Multiply: 55/9 + y = 9Isolate y: y = 26/9um can someone help please and

The well-known state of East Dakota spent approximately $80.8 billion in 2016. Its population at that time was about 3.203 million people. How much did East Dakota spend per capita in 2016? Round to the nearest dollar.
Answer:
$25,226
Step-by-step explanation:
We know that one billion is equal to 1,000 millions
So, we first multiply 80.8 by 1,000 so we can use millions as our unit.
Which gives you $80,800
So, East Dakota spent $80,800 million in 2016 for the 3.203 million people. Right now, we just ignore the "million" part and divide 80,800 by 3.203 which is around 25,226.35029659694
Now we just round it to the nearest dollar and since the tens place is only at 3, we round down.
Hence, our answer is $25,226

· Lucy buys 3 apples and 6 mangos for a total of $9.15.
· Amir buys 8 apples and 4 mangos for 11.92.
What is the cost of a single apple?
Answer:
0.97
Step-by-step explanation:
Let x be the cost of apples
Let y be the cost of mangoes
3x + 6y= 9.15......equation 1
8x + 4y= 11.92........equation 2
Multiply equation 1 by 8 and equation 2 by 3
24x + 48y = 73.2
-
24x + 12y = 35.76
36y = 37.44
y = 37.44/36
y= 1.04
Substitute 1.04 for y in equation 1
3x + 6y = 9.15
3x +6(1.04)= 9.15
3x + 6.24= 9.15
3x = 9.15-6.24
3x = 2.91
x = 2.91/3
x = 0.97
Hence the price of a single apple is 0.97

In chemistry class, Bob recorded the volume of a liquid as 12.7 ml. The actual volume was 12.3 mL. Use
the formula to find percent error of Bob's measurement to the nearest tenth of a percent.
Experimental Value - Actual Valuel
Percent Error =
Actual Value
x 100
The percent error of Bob's measurement is
%.
Answer:
% error = 3.3%
Step-by-step explanation:
Percent Error Formula:
% error = ( (MeasuredValue - AcceptedValue) / AcceptedValue ) * 100
% error = ( (12.7 - 12.3) / 12.3 ) * 100
% error = (0.4/12.3) * 100
% error = (0.03252033) * 100
% error = 3.25203252
% error = 3.3%
A student was interested in studying the relationship between burping and eating at BCs. The hypothesis was that more expensive meals would correlate with more burping. They watched BCs patrons for two weeks and recorded the cost of meals and how often people burped while eating. In this experiment, the independent variable was _________, and they should present the data as a__________ .
a. Burping frequency,
b. Bar graph with error bars
c. Burping frequency
d. Scatter plot with a trendline
Answer:
Price of the meals
Scatter plot with a trendline
Step-by-step explanation:
None of the provided options are correct. The independent variable was Price of the meals, and they should present the data as a Scatter plot with a trendline. The Price of the meal is the independent variable because it does not depend on any other variable and is instead the cause of the burping frequency which would be the dependent variable in this scenario. The Scatter plot would allow you to mark each individual's burping frequency on the same prices for the meal, since you would most likely have more than one value of burping frequency for the same priced meal.

Answer:
4. x = 17
2. x = 77; y = 103
Step-by-step explanation:
4. The acute angles of a right triangle are complementary.
2x + 3x + 5 = 90
5x = 85
x = 17
2.
Same side interior angles are supplementary.
x + 103 = 180
x = 77
y and 103-deg angle are vertical angles, so they are congruent.
y = 103
if if 30 per increase in the salary of usman results in rs.4500 what was the actual salary of usman
Answer:
The actual salary of usman was Rs. 3461.53
Step-by-step explanation:
Given that:
Percent increase in salary = 30%
Total salary percent would be = (100+30)% = 130%
Salary after increment = Rs. 4500
Let,
x be the actual salary before increase.
According to given statement,
130% of x = 4500
[tex]\frac{130}{100}x=4500\\1.3x=4500[/tex]
Dividing both sides by 1.3
[tex]\frac{1.3x}{1.3}=\frac{4500}{1.3}\\x=Rs 3461.53[/tex]
Hence,
The actual salary of usman was Rs. 3461.53

what is the value of x in the equation -2/3 x + 9 = 4/3 x - 3
Answer:
x=6
Step-by-step explanation:
This equation requires simplifying. We start with moving like terms to each other:
3 + 9 = 4/3x + 2/3x
After this, add the like terms together:
12 = 6/3x
6/3 will simplify into 2:
12=2x
Finally, divide both sides by 2:
6=x
Richie and bethany play basketball and practice shooting free throws after school. During one practice session, Richie attempted 15 free throws and made 12 of them.
a. bethany made eight free throws for every 3 that she missed. Did bethany do better than richie? how do you know.
Answer:
Bethany did not do better than Richie because her average score was less than his.
Step-by-step explanation:
Average Value
The average or mean value of m successes out of n tries is given by:
[tex]\displaystyle \bar x=\frac{m}{n}[/tex]
During a practice session playing basketball, Richie made m=12 free throws from n=15 attempts. His average score was:
[tex]\displaystyle \bar x=\frac{12}{15}=0.8[/tex]
Bethany made 8 free throws for every 3 that she missed, this means she made 8 out of 11 attempts. Her average score was:
[tex]\displaystyle \bar x=\frac{8}{11}=0.72[/tex]
Bethany did not do better than Richie because her average score was less than his.
The person that did better is Richie. This is because the percentage of free throws made by Richie is higher than that of Bethany.
In order to determine who did better, the percentage of free throws made has to be determined.
The percentage of free throws made by Richie =( 12 / 15) x 100 = 80%
The percentage of free throws made by Bethany = [(8-3) / 8] x 100 = 62.50%
