Answer:

s = 0.3m

Step-by-step explanation:

Given that 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

9 = 30k ( divide both sides by 30 )

$\frac{9}{30}$ = k

s = $\frac{9}{30}$ m or

s = 0.3m ← equation of variation

Vanessa wants to determine the perimeter around her garden. She makes an small model of her garden and combines all the sides: 3

son4ous [18]

Answer:

Step-by-step explanation:

since it's all addition, we can remove the parentheses

$3x + x + 10 + 5x + 2x + 2 = 56$

Now we combine like terms

$3x+x+5x+2x+10+2=56$

$11x+12=56$

We subtract both sides by 12 to get,

$11x=44$

now we divide both sides by 11

$x=\frac{44}{11}$

$x=4$
