Answer:
Natalie's age is 14
Sasha's age is 17
Step-by-step explanation:
Let
Sasha's age be "s", and
Natalie's age be "n"
<u>Sum of Sasha and Natalie is 31:</u>
s + n = 31
<u>Twice Natalie is 11 more than Sasha:</u>
2n = s + 11
We ca solve this equation for s first:
s = 2n - 11
We put this into first equation and solve for n first:
s + n = 31
2n - 11 + n = 31
3n = 31 + 11
3n = 42
n = 42/3 = 14
Natalie's age is 14
Also, s = 2n - 11
s = 2(14) - 11
s = 28 - 11
s = 17
Sasha's age is 17
Answer:
Step-by-step explanation:
(3/8)*(8/11)=(3*8)/(8*11)= 24/88=12/44=6/22=3/11
or you can symplify 8 and get 3/11 right away.
You should divide or simplify the problem.

Step-by-step explanation:
Just 4 people per year would overflow the landfill, how would it survive 6480 people?
Use the Pythagorean Theorem to check out these possibilities (which you really do need to share here).
Note that 13^2 = 12^2 + 5^2, so 12 and 5 are a possible set of side lengths here.
