X+7x+4-5x+8=12 please help meeee!

Answers

Answer 1

Answer:

Answer:

THERE

Step-by-step explanation:

To solve the equation x + 7x + 4 - 5x + 8 = 12, we can combine like terms on both sides of the equation:

Starting with the left side of the equation:

x + 7x - 5x + 4 + 8 = 12

Combining like terms:

3x + 12 = 12

Next, we can isolate the variable by subtracting 12 from both sides of the equation:

3x + 12 - 12 = 12 - 12

Simplifying:

3x = 0

To solve for x, we divide both sides of the equation by 3:

(3x)/3 = 0/3

Simplifying further:

x = 0

Therefore, the solution to the equation x + 7x + 4 - 5x + 8 = 12 is x = 0.

Solve the question: 12y = 132.
A. Y = 144
B. Y = 1/11
C. Y = 11/12
D. Y = 11

Answers

Answer is D. Y=11 12*y-(-132=0
12y+132=12•(y+11)

$12y = 132$

$(12y)/(12) = (132)/(12)$ $Divide \ both \ sides \ by \ 12$

$\boxed{\boxed{y=11}}$ $Solution$

pizza perfection sold 93 pizzas on Monday, 67 pizzas on Tuesday, 78 pizzas on Wednesday, 44 pizzas on Thursdays, and 123 pizzas on Friday. on average how many pizzas did they sell per day?

Answers

Answer:

On average 81 pizzas they sold per day.

Step-by-step explanation:

Pizza perfection sold pizzas on each days as :

Monday = 93 pizzas

Tuesday = 67 pizzas

Wednesday = 78 pizzas

Thursday = 44 pizzas

Friday = 123 pizzas

To calculate average pizza sold per day we divide total pizzas to number of days.

Total pizza = 93 + 67 + 78 + 44 + 123 = 405 pizza

Therefore 405 ÷ 5 = 81 pizza

On average 81 pizzas they sold per day.

81 average. Average also known as mean means add them all up the divide by the amount of #s

A coat that originally sold for $369.00 is on sale at a 40% discount? How much will you pay for the coat?

Answers

The coat will cost $221.40. If you move a decimal two spaces to the left from 40% (.40) and multiply it by $369.00, you'll get $147.60. You then subtract $147.60 from $369.00 and get $221.40, the final price of the coat.

The best way to work out something like this is to find out what ten percent is. The way in which you do this is to divide the price by 10. This gives you $36.90. Therefore, this is equal to ten percent. As you're looking for forty percent, you need ot mulitply the answer by four, and this gives you $147.60. You then have to subtract $147.60 from $369
$369-147.60= $221.40
