What do you mean doubling? You can add 7+7+7 which equals 21.
4x - 3(x + 5) > 7 - 4(x + 6) |use distributive property; a(b + c) = ab + ac
4x - 3x - 15 > 7 - 4x - 24 |combine items
x - 15 > -4x - 17 |add 15 to both sides
x > -4x - 2 |add 4x to both sides
5x > -2 |divide both sides by 5
x > - 2/5
13.75 + 13.75 = 27.5
27.5 / 2 = 13.75
wz = 13.75
Answer:
wats part A?
Step-by-step explanation:
Give me the data:)
I prefer D.
It's clear that Kevin took (1/4)x.
Keith took (1/4)x -> kevin's amount
* 2 -> twice.
-1 -> 1 less.
So Kevin + Keith = (1/4)x + (1/4)x * 2 - 1 = (3/4)x - 1.
