Answer:
63
Step-by-step explanation:
a) 63
if y = 7x all you have to do is place the 9 where the x is
y = 7(9)
y = 63
3) 12 divided by 3= 4
4 x 2= 8
I think it's 75 if wanting to add up to 180
What is 2.4*10^8 - 3.0*10^8
-60000000
A = 5 / P
5 / A = P
125 goes to 5^3, 5^2 goes to (3+2) x 5, and 50 stays the same.
