Answer:

She subtracted both sides of the equation by 2x.

Step-by-step explanation:

Because she did that, 4x - 2x + 3 = 2x - 2x -18

When subtracting like terms, 2x + 3 = -18

Find the solution to the following: *
Trava [24]

Answer:

First one: x = all real numbers

Second one: x = 0

Step-by-step explanation:

for the first one

given 8x+10=2(4x+5) we need to isolate the variable (x) using inverse operations

step 1 distribute the 2 to what is in the parenthesis ( 4x and 5 )

2 * 4x = 8x

5 * 2 = 10

now we have 8x + 10 = 8x + 10

step 2 subtract 8x from each side

8x - 8x = 0

8x - 8x = 0

now we have 10 = 10

subtract 10 from each side

10 - 10 = 0

10 - 10 = 0

we're left with 0 = 0 meaning that all real numbers are solutions

For the second one

given 3x-8=2(x-4) once again we need to isolate the variable using inverse operations

step 1 distribute the 2 to what is in the parenthesis (x - 4)

2 *x = 2x

2 * -4 = -8

now we have 3x - 8 = 2x - 8

step 2 add 8 to each side

-8 + 8 = 0

-8 + 8 = 0

now we have 2x = 3x

step 3 subtract 2x from each side

3x - 2x = x

2x - 2x = 0

we're left with x = 0

katen-ka-za [31]

Answer: 36.84

(lmk if this isnt right)

Step-by-step explanation:

To find the perimeter of the rectangle:

3+3+3+3+3+3=18

or

3(6)=18

To find the diameter of the circle:

12-(3+3)

12-6=6

You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.

C=πd

Substitute

C=3.14(6)

Multiply

C=18.84

Add the perimeter of the rectangle and the circumference of the circle.

18+18.84=36.84

The length of one side of a square pond is 15 feet. The pond is surrounded by a 3 foot wide walkway. What is the total area of t
rewona [7]

Answer:

Area = 324 ft²

Step-by-step explanation:

Given

Length = 15ft

Walkway = 3ft

Required

Determine the area of the pond + the walkway

To calculate the required area, we need to get the total length of a side .

This is calculated by adding the length of a side of the pond and the side of the walkway

Total Length = Pond Length + Walkway

Total Length = 15ft + 3ft

Total Length = 18ft

Now, the required area can be calculated as thus:

Area = Total Length * Total Length

Area = 18ft * 18ft

Area = 324 ft²
