Answer:
<u>-2</u>
Step-by-step explanation:
Solving :


3(x + 2) = 5(2x + 4)
3x + 6 = 10x + 20
10x - 3x = 6 - 20
7x = -14
x = <u>-2</u>
Answer:
23
Step-by-step explanation:
This equation can be derived from the question
let a represent the initial number Gus started with
{[(a x 8) - 12] / 4 } + 7 = 50
subtract 7 from both sides of the equation
[(a x 8) - 12] / 4 } = 43
Multiply both sides of the equation by 4
(a x 8) - 12] = 172
Add 12 to both sides
8a =184
Divide both sides by 8
a = 23.
Answer:
4.57
Step-by-step explanation:
There are 10 lines in between 4.5 and 4.6, so we can assume each line adds 0.01
The numbers rounded are: 1,800,000 + 5,900,000 The sum of the two numbers is 7,700,000, so C is the answer
