Answer:
18 weeks
Step-by-step explanation:
Total amount of money saved up to buy the printer is T(w), where w is the number of weeks.
Then T(w) = $100 + ($20/wk)w
Setting this equal to $460, we solve the resulting equation for w to determine the number of weeks it took Hugo to save up $460 total:
$460 = $100 + ($20/wk)w, or
$360 = ($20/wk)w, or
w = $360/($20/wk) = 18 weeks

Answer:
21
Step-by-step explanation:
The sum of degrees in a triangle is 180, so we have:
3x+100+x-4=180
add 4 on both sides
3x+100+x=184
subtract 100 on both sides
3x+x=84
Combine like terms
4x=84
84/4 = 21
