So you first want to distribute the 12 into what is inside the parentheses. Then after that all you need to do is simplify!
π * Diameter = 39.8in
Diameter = 12.67in
Since 18in is greater than 12.67in, the ring is not large enough for his act.
I think it would be letter C
Answer:
A. is incorrect. He has to divide 76 by 19, instead of subtracting 19 to 76.
B. This equation has one solution. v=4
Step-by-step explanation:
Hi, Martin’s answer is incorrect.
A. He has to divide 76 by 19, instead of subtract 19 to 76.
The correct steps are:
19v = 76
Since 19 is multiplying the variable, to eliminate it we have to divide by 19.
v = 76/19
v = 4
B. This equation has one solution. It’s v=4
