Answer: The required expression is,
$ 40(0.85)
Step-by-step explanation:
Given,
The original cost of the videogame = $ 40,
Discount percentage = 15%,
So, the amount of discount = 15% of 40
= (0.15)40 ( ∵ 1% = 0.01 )
Hence, the cost of the videogame = original cost - discount
= 40 - (0.15)40
= 40 (1-0.15)
= 40(0.85)
Which is the required expression .
Answer:
16*10^7 or 160000000
Step-by-step explanation:
combine whole numbers: 8*2
and combine exponents: 10^-3*10^10=10^7
8*2*10^7
16*10^7
160000000
4a+3b-(-2a-3b)
=4a+3b+2a+3b
=6a+6b
=6(a+b)
