<h2><u>Problem</u><u>:</u><u>-</u></h2>
  • 20 - 9w = 4 ( 15 - w )

<h2><u>Solution</u><u>:</u><u>-</u></h2>
  • 20 - 9w = 4 ( 15 - w )
  • 20 - 9w = 60 - 4w
  • - 9w + 4w = 60 - 20
  • - 5w = 40
  • w = 40/-5
  • w = - 8

<h2><u>Answer</u><u>:</u><u>-</u></h2>

[Hence, by evaluating the equation 20 - 9w = 4 ( 15 - w ) we got -8 ]

At a pizzeria one day, 12 of the pizzas sold were topped with mushrooms. This represented 15% of all the pizzas sold that day. W
ollegr [7]

Answer:

80

Step-by-step explanation:

So, let's say the total number of pizzas is x

If 15% of x, the total, is 12, then x * 0.15 must = 12

Use this to make an equation

12 = 0.15x

Divide both sides by 0.15 to get x on its own

12 / 0.15 = x0.15 / 0.15

80 = x

80 pizzas were sold

Honestly, I'm trying my best to solve this but my Math XL is being so rude. ​
Valentin [98]
<h3>Answer:  19</h3>

==============================================================

Explanation:

T is the midpoint of PQ, which means T splits PQ into two equal parts. Those parts being PT and TQ.

Set them equal to each other and solve for x.

PT = TQ

3x+7 = 7x-9

3x-7x = -9-7

-4x = -16

x = -16/(-4)

x = 4

So,

PT = 3x+7 = 3*4+7 = 19

TQ = 7x-9 = 7*4-9 = 19

Both PT and TQ are 19 units long to help confirm the answer.
