Describe and correct the error in finding the solution.​

Mathematics

yaroslaw [1]3 years ago

The error is in step 2. if you are performing an operation on one side of the equation, it must be performed on the entire expression. you can’t only divide by 2 on one term, you must do it to everything in the equation. instead, you could add 6 to both sides first, giving you 2x = -4. Then you can divide by 2 on both sides. the answer is -2.

A car needs fixing and Abe can fix it for $70 per hour with a $130 part, but Gabe can fix it for $80 an hour with a $40 part.How
patriot [66]

Answer:

9 hours

Step-by-step explanation:

Abe's charge  =   Gabe's charge

$130+($70/hr)h = $40+($80/hr)h

Then 130 + 70h = 40 + 80h, or

           90           =   10h, or h = 90/10 = 9

When 9 hours have passed, the amount charged by each person will be temporarily equal.

4. Determine the following difference. (2x² + 3x - 10) - (x² - x + 111)  please explain
SIZIF [17.4K]
Hi there! The answer is A.

(2x² + 3x - 10) - (x² - x + 111) 
Let's solve this problem step by step!

First work out the parenthesis. Because we multiply by negative 1, we mustn't forget to change the symbols in front of the factors.
2x² + 3x - 10 - x² + x - 111

Now rearrange our expression, in order to collect the terms later.
2x² - x² + x + 3x - 10 - 111

And finally collect the terms.
x² + 4x -121

The answer is A.
