Answer:
A.) Kathy starts each week with 108 phones to fix.
3 -

=

- 7
First, simplify

to

/ Your problem should look like: 3 -

=

- 7
Second, simplify

to

/ Your problem should look like: 3 -

=

- 7
Third, multiply both sides by 9 (the LCD of 9,3). / Your problem should look like: 27 - 2b = 3b - 63
Fourth, add 2b to both sides. / Your problem should look like: 27 = 3b - 63 + 2b
Fifth, simplify 3b - 63 + 2b to 5b - 63. / Your problem should look like: 27 = 5b - 63
Sixth, add 63 to both sides. / Your problem should look like: 27 + 63 = 5b
Seventh, simplify 27 + 63 to 90. / Your problem should look like: 90 = 5b
Eighth, divide both sides by 5. / Your problem should look like:

= b
Ninth, simplify

to 18. / Your problem should look like: 18 = b
Tenth, switch sides. Your problem should look like: b = 18
Answer:
b = 18
Answer:
45
Step-by-step explanation:
Let's call the missing side x
This is a right triangle and in right triangles the square length of hypotenuse is equal to sum of square length of base and side lengths
53^2 = 28^2 + x^2
x = 45

Step-by-step explanation:
Answer:
W'(-3,3) V'(-4,3) U'(-4,5)
Step-by-step explanation:
The mapping for 90 degrees counterclockwise rotation is;

The given points have coordinates: W(3,3) V(3,4) U(5,4)

This implies that:



The required points of the image are:
W'(-3,3) V'(-4,3) U'(-4,5)
