x = (y + 2)/7
7x = y + 2
y = 7x - 2

answer - A. p(x) = 7x - 2

5x + 5 = x + 45<br><br> PLEASE HELP

Ostrovityanka [42]

$5x+5=x+45$

We'd rather not have x on both sides of the equation when trying to solve this. To eliminate the x on the right side, subtract both sides by x.

$5x+5-x=x+45-x$
$4x+5=45$

Let's get eliminate the "5" on the left side. Subtract both sides by 5.

$4x+5-5=45-5$
$4x=40$

To finish this, divide both sides by 4.

$4x \div 4=40 \div 4$
$x=10$

That is the answer. Hope this helps! :)

Your teacher writes the fact below on the board.Using only mental math, will the answer be less than or greater than 5? How do y

Levart [38]

Answer:

Less than 5

Step-by-step explanation:

The eason behind the answer being less than 5 is because if you multiply something by a fraction that is less than a whole number, then you will get less than the original number you multiplied the fraction with.

Hope this helps :)
