Answer:
Step-by-step explanation:
<em>Cost of game = $120</em>
<em>Current savings = $30</em>
<em>Rate for babysitting (per hour) = $5/hour</em>
<em></em>
<em>So, required equation is :-</em>
<em>120 = 5h + 30</em>
<em>5h = 90</em>
<em>h = 18</em>
<em></em>
<em>She must make $90 by babysitting for 18 more hours.</em>
<u>Answer:</u>
<u>Step-by-step explanation:</u>
To find the solution to the equation, we have to rearrange the equation to make 
the subject:
⇒ 
[Subtracting 2 from both sides]
⇒ 
⇒ 
[Subtracting 
from each side]
⇒ 
⇒ 
[Diving both sides by 213]
⇒
A = 1/2aP
P = number of sides x length of each side
P = 8 x 5.8
P = 46.4
A= 1/2 x 7 x 46.4
A = 162.4
8:5 x:7
8/5=x/7 Solve for x
x=11 1/5 or 11.2 liters
