Answer: 32.85 is 9 copies of 3.65
Explanation:
According to question we are asked to determine the value of 9 copies of 3.65 which means we have add 3.65 nine times:
3.65 + 3.65 + 3.65 + 3.65 +3.65 + 3.65 +3.65 3.65 + 3.65 = 3.65(1+1+1+1+1+1+1+1+1)=

Answer:
10 =x
Step-by-step explanation:
Let h(x) = -2x - 5. If h(x) = -25
-25 = -2x-5
Solve for x
Add 5 to each side.
-25+5 = -2x-5+5
-20 = -2x
Divide by -2
-20/-2 = -2x/-2
10 =x
