2:5
Multiply both parts of the ratio by 5 to get the answer of
10:25
You will need about 2 gallons of paint
Answer: B
Step-by-step explanation:
A) The answer is one solution, neither
6x + 2(2x - 3) = 24 + 9x
6x + 2 * 2x + 2 * (-3) = 24 + 9x
6x + 4x - 6 = 24 + 9x
10x - 6 = 24 + 9x
10x - 9x = 24 + 6
x = 30
b) The answer is infinity solutions, identity
<span>25 – 4x = 3(5 – x) + 10 – x
25 - 4x = 3 * 5 - 3 * x + 10 - x
25 - 4x = 15 - 3x + 10 - x
25 - 4x = 25 - 4x
4x - 4x = 25 - 25
0x = 0
x can be any number, so an infinite number of solution
c) The answer is no solution, contradiction
</span><span>4(x + 2) = 2x + 7 + 2(x – 10)
4 * x + 4 * 2 = 2x + 7 + 2 * x - 2 * 10
4x + 8 = 2x + 7 + 2x - 20
4x + 8 = 4x - 13
4x - 4x = - 8 - 13
0 = -13
this is contradiction</span>
