What are the steps of 5x+1+12x-8=180?

Answers

Answer:

Combine like terms: (5x+12x)+(1+−8)=180

17x- 7 = 180

Add 7 to both sides: 17x = 187

Divide by 17: x=11

Step-by-step explanation:

Answer:

x = 11

Step-by-step explanation:

First put all the number on one side so its easier to add them up.

add the x's then do the regular numbers.

5x + 12x = -1 + 8 + 180

17x = 187

Then simplify it. so 17 can go into 187 11 times.

X = 11

Answers

-1/3, -1/5, 0, 1/8
u put the negative numbers to the left and positive ones to the right then since -1/3 is more negative than -1/5, -1/3 goes to the left and-1/5 goes next to it and then 0 and since 1/8 is the biggest it goes to the right
Since it’s negative the negative is the least but there two of them so you have to convert them to decimales
1/3 = .333333 and 1/5 is .2
So 1/3 goes first then 1/5
1/8 is .125 it’s larger than 0
So your answer is
1/8 0 1/3 1/5

Here is my question! first gets brainliest!!!! the question is in the picture,

Answers

Answer:

8 dimes, 15 quarters

Explanation:

The number of dimes=x

The number of quarters=x+7

So the value of each dime and quarter is 0.10 and 0.25

0.1x+0.25(x+7)=4.55

0.1x+0.25x+1.75=4.55

0.35x+1.75=4.55

0.35x+1.75–1.75=4.55–1.75

0.35x=2.8

0.35x/0.35=2.8/0.35

x=8

So the number of dimes there are is 8.

The number of quarters:

x+7

=8+7

=15

So, the number of dimes and quarters in this order are: 8 and 15.

11 quarters and 18 dimes!

What is the total surface area of this square pyramid?

A square pyramid. The square base has side lengths of 9 millimeters. The triangular sides have a height of 12 millimeters.

_____________ mm2

Answer: The correct answer is 297 (C)

Step-by-step explanation: I got it correct!!. Hope this helps :)

The area of a 2D form is the amount of space within its perimeter. The total surface area of the square base pyramid is 297mm².

What is an area?

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The total surface area of the square pyramid is the sum of the area of the triangles and the area of the base. Therefore, the total surface area is equal to,

Total surface area = Area of square base + 4(Area of a triangular face)

                               = (9mm)² + 4(0.5×9×12)mm²

                               = 81mm² + 216mm²

                               = 297mm²

Hence, the total surface area of the square base pyramid is 297mm².
