<em>We can multiply 2 by 30.45 in order to get 60.90</em>
<h2>
Explanation:</h2>
Suppose you have two numbers x and y. We can write an equation such that:

For this equation we have infinitely many solutions. Let's say x equals 2 in this case, so we can isolate y in order to solve this problem:

So <em>we can multiply 2 by 30.45 in order to get 60.90</em>

Answer:
The answer is C
Step-by-step explanation:
Expand
x^2+3x-10=18
minus 18 both sides
x^2+3x-28=0
find what 2 numbers mutiply to -28 and add to 3
7 and -3
(x+7)(x-3)=0
set each to zero
x+7=0
x=-7
x-3=0
x=3
x=-7 and 3
