Answer:
s = 
m
Step-by-step explanation:
Given s varies directly with m then the equation relating them is
s = km ← k is the constant of variation
To find k use the condition s = 9 when m = 30 , thus
9 = 30k ( divide both sides by 30 )
k = 
=
s = m ← equation of variation
Answer:
y should equal 1 7/8 (or 15/8).
Step-by-step explanation:
Answer:
even
Step-by-step explanation:
= 27 + 45
Take 9 as a common,
= 9(3+5)
'cause 9 times 3 is 27 & 5 times is 45
In short, Your Answer would be Option C

For this item, I assume that Svetlana's hair is 4 cm long and she wanted it to be at least 7 cm long.
We let x be the number of months it will take for her hair to be 7 cm long. The sum of the product of x and the rate and the initial length should be at least 7. Mathematically,
1.51x + 4 ≤ 7
