Hey!
91 ÷ 7 = 13
So, we know that Luke paints one portrait every week.
13 × 4 = 52
So, Luke paints 52 portraits in 4 weeks.
Answer:
x=10
ST=10
TU=100
Step-by-step explanation:
2x-10 + 5x+50 = 110
2x+5x=110+10-50
7x=70
x=10
2(10)-10
20-10=10
5(10)+50
50+50=100
Answer:
D 36
Step-by-step explanation:
<em>Write the information algebraically</em>
c = 3a
c + a = 48
c = children, a = adults
<em>In the second sentence (in bold), we can replace c with 3a</em>
c + a = 48 → 3a + a = 48
<em>Simplify</em>
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
<em>We can then substitute or plug in a = 12 into the original equation:</em>
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)
<h3>There are 36 children</h3>
