Nadine wants to convince her school to provide the students with an extra playground.
ICE Princess25 [194]

Answer:

The school would have to give $300 and each side would be 100cm

Step-by-step explanation:

(4x - 8)cm = Side length

Solve for X

3(4x - 8) = 300

(Getting rid of the three)

(12x -24) = 300  

(Getting rid of the 24)

(12x) = 324

(Getting rid of the 12)

(12x/12) = 324/12

X = 27

27 x 4

Side length = (108 - 8)

108 - 8 = 100cm

100 x 3 = 300cm (1cm = $1)

$300

Each Side would be 100cm

V1/V2=T1/T2. Solve for V1
Ahat [919]
V1=(T1/T2)*V2
In this problem, since you are given no actual numbers, the only thing you can do is multiply V2 over to get V1 alone. Since you can't cancel anything out, you are left with the answer above.

natta225 [31]

Answer:

\huge \boxed{x=180}

Step-by-step explanation:

15% of x = 27

\sf 15\% \cdot x =27 \\\\\\ 0.15x=27 \\\\\\ Divide \ both \ sides \ by \ 0.15. \\\\\\ \frac{0.15x}{0.15}  = \frac{27}{0.15} \\\\\\ x = 180

15% of 180 is 27.
