Is it positive 42 or negative?
8v = 2v + 42
-2v -2v
6v = 42
v=7
8×7 = 56
2×7+42--> 14+42=56

$\frac{(5x-18)(x)}{2} =35$
$(5x-18)(x)=70$
$5x^2-18x-70=0$
By the time you factorize this, you will get
x = 5.9521078984053 or <span>-2.3521078984053

Answer:

Ron got 3 additional toppings

Step-by-step explanation:

Lets call the amount of toppings that Ron got t. With this, we can set up the following equation:

8.95+0.65t=10.90

Subtract 8.95 from both sides:

0.65t=1.95

Divide both sides by 0.65:

t=3
