8.50 * 0.06 = 0.51
0.51 + 8.50 = 9.01
10.00 - 9.01 = 99
He will receive 99 cents in change.
B. 10+3x=5
3x=-5 (subtract 5 both sides)
X=. -5/3 (divide both sides by 3)
C. A+x = b
X = b-a (just get x alone)
D. Cx = d
X = d/c
Answer:
3 + 3.75x=18
subtract 3 from both sides
3.75x=15
divide by 3.75 on both sides
x=4
Step-by-step explanation:
I think It would probably be 1
To isolate the variable means to have it by itself on one side of the equation, where the variable equals an expression.
To isolate 
, we will need to remove the variables and other terms "connected" to the variable:
By dividing terms "connected" to our variable, we have isolated it one side of the equation.
