Please help me I've been stuck on this one question and I can't find the answer to it.
For four Fridays in June, Grace earned $21.50, $29.75, $32.00, and $15.25 from babysitting.
In July, she earned $8 more for babysitting four Fridays than she did in June.
What is the increase in the mean for July compared to June?
Round the answer to the nearest penny.
Answer:
$2
Step-by-step explanation:
Its actually quite simple.
first find the mean for june.
add $21.50 + $29.75 + $32.00 + $15.25
that is equal to 98.5
then divide by 4.
that is 24.625
do not round to the nearest penny yet.
now you need to find the mean for july.
just add $8 to the total amount you made in june to find the total amount you made in july.
that is 106.5
then divide that by four because you worked four fridays in july as well.
that is 26.625.
finally you need to find the difference between 26.625 and 24.625.
26.625-24.625= 2
and ta-da!!!
the answer us $2.
your welcome. tell me if it is correct.

Written in slope-intercept form, the equation Ax + By = C become
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
Ax + By = C ( subtract Ax from both sides )
By = C - Ax ( divide all terms by B )
y = [tex]\frac{C}{B}[/tex] - [tex]\frac{A}{B}[/tex] x , that is
y = - [tex]\frac{A}{B}[/tex] x + [tex]\frac{C}{B}[/tex] → C

What is the slope of points (2,-15) and (-3,10).
Answer:
m = 5
Step-by-step explanation:
I believe you are asking, "What is the slope of the line passing through the points (2, -15) and (-3, 10)?"
As we go from (-3, 10) to (2, -15), x (the horizontal leg of a right triangle) increases by 5 (this is the 'run'), and y (the vertical leg) increases by 25 (the 'rise'). Thus, the slope of this line is
m = rise / run = 25/5, or just 5. m = 5

Answer:
A. x = 2, y = 12
Step-by-step explanation:
You can solve this problem using similar triangles; you know the triangles are similar because each of the two legs of the triangles are cut in half, meaning the line 5x - 3 is parallel to x + 12. Because of the nature of this figure (the line that is length 5x - 3 cuts the triangle exactly halfway), you can write an equation to find x:
2(5x - 3) = x + 12 (this is a property of triangles when a line is parallel to a base and intersects the triangle at half of that base's height. The line would be half the base)
10x - 6 = x + 12 (simplify)
9x - 6 = 12 (subtract x from both sides)
9x = 18 (add 6 to both sides)
x = 2 (divide both sides by 9)
At this point, you could just click A since that's the only problem where x = 2, but for the sake of properly explaining this problem, I'll continue to find y.
In the image, y + 8 is equal to 2y - 4, shown by the short lines intersecting each side signifying congruence. Now, you can write an equation for this and solve:
y + 8 = 2y - 4
8 = y - 4 (subtract y from both sides)
y - 4 = 8 (switch it around so y is on the left; you don't have to do this, but I think it makes the problem more comfortable to solve)
y = 12 (add 4 to both sides)
