$430.88.

Q: Find Jeff's total earnings if his sales are$948.
Answer:
His total earnings for sales of $948 is $425.84
Step-by-step explanation:
Let the percentage of his commission be a percentage with its value represented as x and b be his base salary , y as his total earnings
So we have;
y = x% of sales + base salary
for 849 sales and 417.92 , we have
417.92 = 8.49x + b •••••••(i)
for 1011 sales and 430.88 servings
430.88 = 10.11x + b ••••••(ii)
Subtract i from ii
12.96 = 1.62x
x = 12.96/1.62
x = 8
To get b, we substitute
430.88 = 10.11(8) + b
b = 430.88 - 10.11(8) = 350
Commission is 8% , base earnings is $350
So for total sales of 948;
y = 8% of 948 + 350
y = $425.84

One number is 2 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 468 , find the numbers
Answer:
Step-by-step explanation:
Givens
Let the first number = x
Let the second number = 2x
Let the third number = x + 100
Total = 468
==============
Solution
x + 2x + x + 100 = 468 Combine the xs
4x + 100 = 468 Subtract 100 from both sides
4x = 468 - 100
4x = 368 Divide by 4
x = 368/4
x = 92
===============
Answer
First number = 92
Second num = 2 * 92= 184
Third number = 92 + 100= 192
Total 468

Why do we use fractions to represent slope?
Answer:
The formula for slope is sometimes referred to as "rise over run", because the fraction onsists of the "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).

Answer:
x = 12°
Detailed explanation down below.
Step-by-step explanation:
Ill be delighted to help
8° + 6x is an exterior angle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
In this situation, those two angles are 30° and 4x+2°
So lets put this in an equation
30° + 4x + 2° = 8° + 6x
4x + 32° = 6x + °8
Now lets subtract 8° from both sides to make it simpler
New equation =
4x + 24° = 6x
Lets evaluate X=
6x - 4x = 24°
2x = 24°
x= 24/2
x= 12°

The two prisms below are similar. What is the value of x?
24
4
16
A. 4
B. 24
C. 16
D. 1
Answer:
A
Step-by-step explanation:
Since the prisms are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{16}{4}[/tex] = [tex]\frac{x}{1}[/tex] ( cross- multiply )
4x = 16 ( divide both sides by 4 )
x = 4 → A
The value of x on the prism is 4.
What are Similar Figures?Similar figures are those figures which are having the same shape, but the sizes are different.
Given are two prisms.
We have to find the length of x.
Given that they are similar.
So the ratio between their dimensions is equal.
So,
x / 1 = 16 / 4
x = 4
