Answer:
Pam 6
Tia 8
Veronica 11
Lily 15
Step-by-step explanation:
Tia's age = 8
Pam's age = Tia's age - 2
8 - 2 = 6
Veronica = pam's age + 5
6 + 5 = 11
Lily's age = veronica's age + 4
11 + 4 = 15
Answer: 11
Step-by-step explanation: write the equation.
2(x+4)=30
Divide by 2
x+4=15
Subtract 4
x=11

</span>Use PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
Solve exponent first
<span>8.42 x 10^3
</span>8.42 x 1000
Solve the rest
8.42 x 1000
8420
8420 is between
