Answer:

1)m= -1

2)x=4/7

Step-by-step explanation:

1)Subtract 7m from both sides. 2)Step 1: Subtract 2x from both sides.−5x+3−2x=2x−1−2x -5x+3-2x=2x-1-2x

-7x+3=-1

Step 2: Subtract 3 from both sides

−7x+3=−1 -7x+3-3=-1-3

Step 2: Subtract 3 from both sides. -7x=-4

Step 3:Divide both sides by -7

−7x+3−3=−1−3 -7x/7=-4/7

−7x=−4

Step 3: Divide both sides by -7. x=4/7

−7x

−7

−4

−7

5m+4−7m=7m+6−7m

−2m+4=6

Step 2: Subtract 4 from both sides.

−2m+4−4=6−4

−2m=2

Step 3: Divide both sides by -2.

−2m

−2

m=−1

This is a pyramid problem so please help out

Degger [83]

Answer:

Step-by-step explanation:

LA, Laterial Surface Area, is the lateral surface area of a pyramid. In this case, it is the sum of five triangles with base of 12cm and height that can be calculated as follow:

height^2 = 8.26^2 + 20^2 = 468.23

height = 21.64cm

LA = 5*1/2*12*21.64

= 649.2cm^2

SA, Surface Area, is the sum of LA and base area.

Base area = 5*1/2*12*8.26 = 247.8cm^2

SA = 649.2 + 247.8 =897cm^2

Volume, V = 1/3 * base area * height

= 1/3 * 247.8 * 20

= 1652cm^3

prohojiy [21]

Answer:

<u>212,400 items</u> were sold in 10 months.

Step-by-step explanation:

Given:

Items sold this month = 70,800

Percent Increase in every month = 20%

We need to find number of items sold in coming 10 months.

Solution:

First we will find number of items increase in each month.

number of items increase in each month can be calculated by Percent Increase in every month multiplied by Items sold this month and the divided by 100.

number of items increase in each month = $\frac{20}{100} \times 70800 = 14,160$

Now we will find number of item sold in 10 months.

number of item sold in 10 months is equal to sum of Items sold this month and number of items increase in each month multiplied by 10.

framing in equation form we get;

number of item sold in 10 months = $70800+10\times 14160 = 212,400$

Hence <u>212,400 items</u> were sold in 10 months.
