If the TV is 70% off, then that means she paid 30% of the original cost. If 30% of the original cost is $120, then...
30% * x = 120
.30x = 120
x = 120/.30
x = 400
The original cost was $400
Answer:
Total number of combination = 32
Step-by-step explanation:
Given:
Number of cars = 3
Number of models = 2.
Number of color = 4
Find:
Total number of combination
Computation:
Total number of combination = [2³ x (2x3) x 4] / !3
Total number of combination = 32
20 and 45x
We look for a number that can go into both numbers.
5 into 20 is 4 and 5 into 45x is 9x.
5: 20 45x
4 9x
So no other number can go into 4 and 9x again.
So the GCF of 20 and 45x is 5.
Hope this explains it.
