d. 54 ÷ 6 = 9
e. 42 ÷ 7 = 6
f. 63 ÷ 9 = 7
g. 36 ÷ 4 = 4
h. 45 ÷ 9 = 5

Answer:
-15
Step-by-step explanation:
Step 1: Multiply 3 by both sides
3(2/3x)=3(-10)
Step 2: Simplify
2x=-30
Step 3: Divide both sides by 2
2x/2=-30/2
Step 4: Simplify
x=-15

-The answer for the radius:

Step-by-step explanation:
-The equation of a circle is:
(where the center is known as
, the point is
and the radius known as
).
-Use both the center (-2,-1) and the point (-7,-7) for the equation:

-Then, solve the equation to get the radius:






So, therefore the radius is
.
