2 x 5/ 50 x 18
10 / 900
Divide both by 10
1/90
Answer:
15
Step-by-step explanation:
If y is 20 when x is 5 then x is always 1/4 of y
60*(1/4)=15
A is correct:
Let volume v, length l, and h height.
v= (l²h)/3
v=(x²9)/3
v=3x²
Let the two ages be j and m, respectively. Then j+m>32.
Solving for Mary's age, we get m > 32 - j. Because j = m + 2, m > 32 - (m+2).
Continue solving for m: Adding m to both sides of this inequality results in
2m > 32 - 2. Then 2m > 30, and m > 15. Mary's age is greater than 15.
