Answer:
m = - 1
Step-by-step explanation:
9m + 13 = 4
subtract 13 from both sides
9m = 4 - 13
9m = - 9
divide both sides by 9
m = - 1 (negative 1)
Nick has $50. He just got a job as a construction worker making $10 an hour. He wants to earn enough money to buy himself a new cell phone, valued at $900. If x represents the number of hour he works, write an inequality to represent this situation. What is the minimum number of hours must he work to buy the phone?
Answer:
900[tex]\geq[/tex]50+10x; At least 85 hours
Step-by-step explanation:
Nick must make at least 900 dollars, so the amount he has + earns must be greater than or equal to 900 in order to walk out of the store with it.
50 is the amount that Nick already has, and add that to 10x, which gives $10 for every x hour.
To solve, subtract 50 from each side.
850[tex]\geq[/tex]10x
Divide by 10 to solve for x:
85[tex]\geq[/tex]x
Nick must work at least 85 hours.
Is the list of numbers an arithmetic sequence?
22,25,27,30,33,…
Answer:
No
Step-by-step explanation:
The jump from each of the numbers is 3 but from 25 to 27 is 2 therefore it is not an arithmetic sequence.

Without calculating any statistics, Jadyn knows that data set 1 would have the least mean absolute deviation among the three sets. Which statement explains how she knows?
Sets 2 and 3 have an even number of values.
Set 1 has the least number of values.
Sets 2 and 3 contain outliers.
Set 1 contains an outlier.
Answer:
data set 3 would have the least mean absolute deviation among the three sets since there is less spread of the data and the data values in set-3 lie close to the mean.
Step-by-step explanation:
The mean absolute deviation is a measure of spread of the data.
If the data values in the given data set are widely spread then we obtain a higher mean absolute deviation.
if the data values of a given data set are close to each other i.e there is a less spread of the data and hence the mean absolute deviation will be low as the data values will lie close to the mean.
We are given three data set as:
set- 1 42, 48, 50, 88, 49
set- 2 63, 29, 35, 28, 30
set- 3 2, 5, 3, 8
Hence, we could observe that the data values in set 1 and set 2 are widely spread.
In set-1 the data value 88 is much higher value as compared to other data values.
Similarly in set-2 the data value 63 is again a much higher value as compared to other data values.
Whereas in set-3 the data values are all closely related and there is not much spread in the data.

x=?
y=?
Answer:
y = 2
x = 4
Step-by-step explanation:
The given is a special right triangle, the measure of its interior angles is as follows:
90-60-30 and side lengths would be:
2a - a[tex]\sqrt{3}[/tex] - a
as shown in image the side length that sees angle measure 60 is 2[tex]\sqrt{3}[/tex]
so the number represented by a is = 2 therefore y = 2 and x = 4
One of Kylie's homework problems is to convert 30 centimeters to feet, given that 2.54 centimeters = 1 inch. Here is her
work:
30 centimeters
2.54 centimeters 12 inches
= 30 x 254x12=914 4 feet
1 inch 1 foot
Which of the following statements is true?
Kylie's conversion is correct
Kylie's conversion is incorrect because she set up the conversion ratios incorrectly.
Kylie's conversion is incorrect because she multiplied incorrectly
Kylie's conversion is incorrect because her conversion ratios are not equivalent to 1.
Answer:
She set up the conversion ratios incorrectly.
Step-by-step explanation:
30 cms
= 30 / 2.54 inches
= 30 / 2.54 / 12feet
= 0.984 feet.

Answer:
Step-by-step explanation:
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. A rational function is a function of the form f(x)=p(x)q(x) , where p(x) and q(x) are polynomials and q(x)≠0 .

if x is the exterior angle and 70 and 50 are its opposite interior angle of a triangle find x please help me
Answer:
x = 120
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, then
x = 70 + 50 = 120
Answer:
X=120
Step-by-step explanation:
exterior angle of triangle is equal to its two opposite interior angles .
hence, X= 70 + 50
= 120

Answer:
correct the answer is 7[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The required cups of floor needed to make his cookies is 7 1/2 cups. Option D is correct.
Given that,
Nate is baking cookies for a bake sale. He needs 2 1/4 cups of flour for each batch of cookies, and he needs to make 3 1/3 batches, how much flour does Nate need to make his cookies is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Amount of floor for each batch of cookie = 2 1/4
Total floor required to bake 3 1/3 batches = 9 / 4 × 10 / 3 = 7 1 / 2
Thus, the required cups of floor needed to make his cookies is 7 1/2 cups. Option D is correct.

can someone pls help me with solving one variable expressions pls show your work too so i can understand thanks
Step-by-step explanation:
Basically, let's represent the amount of money earned in
July with x
and
August with x+90
x+(x+90)=350
2x+90=350
2x=350-90
2x=260
x=260÷2
x=130
So, Wanda earned $130 babysitting in July and in July, 130+90=$220.

The x-coordinate of the left endpoint is 5.
The x-coordinate of the right endpoint is x.
length = x - 5
Find the measures of the interior angles.
The three inside angles of a triangle when added together need to equal 180 degrees.
