Answer:
Ava's share = $20
Charlotte's share = $16
Step-by-step explanation:
15x + 12x = 36 : multiply each girl's age by same amount and adding gives $36
27x = 36 : add x terms
x = 36 / 27 : divide both sides of equation by 27
x = 4 / 3
Ava's share = 15x = 15 * 4/3 = 20
Charlotte's share = 12x = 12 * 4/3 = 16
Answer:
3
Step-by-step explanation:
using the rule of radicals
× 
⇔ 
= 
= 
× = 3
F(x)=2(x+10)=24
2(x+10)=24
divide 2
x+10=12
minus 10
x=2

Answer:1.41666666667 or to simplify, 1.416 but the 6 is repeating so draw a bar over the 6.
Step-by-step explanation:
<h3> </h3>
X-4/3 <= 5
Multiply both sides by 3:
X-4 <= 15
Add 4 to both sides:
X <= 19
The answer is the third one.
