Answer:
A
Step-by-step explanation:
You didn't share the price list of the items... but together they have $12.00
74% means 0.74
"of" means "times"
So, 128 = 0.74 times (the number)
Divide each side of this equation by 0.74 :
128/0.74 = the number
<em>172.973</em> (rounded) = the number
The rule of the numbers are to add 6 therefore when -9 is added by 6 it becomes -3 and -3 take away 6 is 3 and then 3 plaza 6 is 9
For number 2 problem:
10x=5y
15x=7.5y
20x=10y
For problem3:
3x=1.5y
4x=2y
5x=2.5y
