Well.... first lets break this problem up. and work on the left side first
soo we solve this ↓
14/21.2 = 0.66
now lets plug in our values. The left side will just be replaced by 0.66
Soooo
0.66 = n/15
so this means we do the opposite on both sides of what n and 15 are doing
In this case they are dividing so yes we are doing the opposite by multiply.
sooooo
0.66 = n/15
×15 = x 15 they cancel out on the right hand side and lets solver for the left side.
0.66 x 15 = 9.9
so that means
n = 9.9
or we could round it and just say 10
n = 10
hope this helps:P
Answer:
⅜
Step-by-step explanation:
30/80
= 3/8
Answer:
x=27
Step-by-step explanation:
3=x/9
9*3=(x/9)*9
27=x
x=27
Multiply by 9 on both sides to get the x by itself because x(1/9)*9=x, and when you do something to one side of the equation you also have to do it to the other side.
Answer:
d
Step-by-step explanation:
We just need to use the formula:
c = 3.14(r)²
So we can insert the radius here
c = 3.14(7)²
c = 3.14(49)
c = 153.86
So your answer is d.
7+2h= g. Add 2h to other side to make g alone
3(7+2h) + 3h = 10 Substitute
21+6h +3h= 10. Distribute
9h= -11
H= -11/9
