Black_prince [1.1K]

Step-by-step explanation:

Will bought several books that cost $ 2.50 each and received a $ 2 discount on the total bill. If he paid $ 10.50, how many books did he buy ?

2.50x - 2.00 = 10.50

2.50x = 10.50 + 2.00

2.50x = 12.50

x = 12.50/2.50

x = 5....he bought 5 books

Answer: 1.) 14.66666666666667
2.) 20

Steps:
1.) 180 = 3x + 136
180 -136 = 3x
44 = 3x
44/3 = x
14.66666666666667 = x

2.) 70 + x = 90
x = 90 - 70
x = 20

I would appreciate brainliest if this was helpful and correct! ;)

$12x^4(- \frac{5}{6} x^3y^2)$

---------------------------------------------------------------------------------------
Multiply the constant: 12 x (-5/6)
---------------------------------------------------------------------------------------
$-10x^4( x^3y^2)$

---------------------------------------------------------------------------------------
Multiply the x (we add the power together when we multiply)
---------------------------------------------------------------------------------------
$-10x^7y^2$
