Answer:

x

Step-by-step explanation:

3x-2>5x+10

Add 2 to both sides

3x-2+2>5x+10+2

Simplify

3x>5x+12

Subtract 5x from both sides

3x-5x>5x+12-5x

Simplify

-2x>12

Multiply both sides by -1 (reverse the inequality)

(-2x)(-1)

Simplify

2x

Divide both sides by 2

\frac{2x}{2}

Divide the numbers: \frac{2}{2} =1

=x

Divide the numbers: \frac{-12}{2}

Apply fraction rule: \frac{-a}{b} =-\frac{a}{b}

=\frac{12}{2}

Divide the numbers: \frac{12}{2} =6

=-6

Can someone please explain to me how to work this out?
Ludmilka [50]

Answer:

B

Step-by-step explanation:

the way i work it out is if you take the product and power it to the third you can easily find out which answer is correct. another way, if you don't have a calculator is to look at the last digit in the number in the square root sign.

For example, 3 square root 64 equals 8. you would look at the 4 and try to find 3 numbers that end in 4 OR is divisible three times by the number. 64 is exactly divisible by 4 only 3 times so you know that it can't be 8.

hope this helps!
