Step-by-step explanation:
X + 9= 7
get x by itself you -9 on both sides
X + 9 = 7
- 9. -9
X = -2
(2/3)*(c-18)=7 <em>(Multiply terms on both sides of equation by 3)</em>
2(c-18)=21
2c-36=21
2c=57
c=57/2
c=28.5
Answer:
B
Step-by-step explanation
dilation meaning shrink therefore it still similar shape but smaller so it is not congruent.
Answer:
x=2
Step-by-step explanation:
6^x^10 = 6^12^2 / 6^4
We know a^b^c = a^(b*c)
6^ 10x = 6^(12*2) / 6^4
6^ 10x = 6^(24) / 6^4
We know a^b / a^c = a^(b-c)
6^ 10x = 6^(24 -4)
6^ 10x = 6^(20)
Since the bases are the same, the exponents are the same
10x = 20
Divide each side by 10
10x/10 = 20/10
x=2
