Answer:

x = -24/7

Step-by-step explanation:

To solve, you need to multiply both sides by 10 ( the GCF of 5 and 2) to get rid of the fractions. Once multiplied, you get this:

2(4x-2) + 5(1) = 5(3x+7) - 10(1)

Now, just distribute the parenthesis:

8x - 4 + 5 = 15x + 35 - 10

Now, combine like terms:

8x + 1 = 15x + 25

15x + 25 = 8x + 1 (rearranged the equation)

Subtract the x's:

7x + 25 = 1

Now solve:

7x = -24

x = -24/7

Solve the inequality and enter your solution as an inequality comparing the variable to the solution in the box below. 18 + x &g
storchak [24]

<em><u>Hi there! :)</u></em>

<em><u>Answer:</u></em>

<em><u>x>24</u></em>

<em><u>*The answer must have a positive sign and greater than symbol sign.*</u></em>

<em><u>Step-by-step explanation:</u></em>

First, you switch sides.

x+18>42

Then, you subtract by 18 from both sides of an equation.

x+18-18>42-18

Finally, you subtract by the numbers from left to right.

42-18=24

<u><em>Final answer is x>24</em></u>

I hope this helps you!

Have a nice day! :)

Help! Will give brainly! Explain why the value x=4 is not a solution to the inequality 2x&gt;10
melamori03 [73]

Answer

8 is not greater than 10

Step-by-step explanation:

2x>10

2(4)>10

8<10

x=4 can not be the solution to this equation because 8 is less than 10

*just as a side note think of the > sign as an alligator, the mouth always is open towards the larger number

The area of the top face of a cube is 16 square inches. Use 8 of these cubes to make a rectangular
KengaRu [80]

Answer:

The volume of the rectangular prism is 512 inches³

Step-by-step explanation:

Any cube has 6 square faces

Area of any square = L × L, where L is a length of each side

The volume of the cube = L × L × L

∵ The area of the top face of a cube = 16 inches²

→ Find which number multiply by itself = 16

∵ 16 = L × L

∵ 16 = 4 × 4

∴ L = 4 inches

Let us find the volume of 1 cube

∵ The volume of the cube = L × L × L

∵ L = 4 inches

∴ The volume of each cube = 4 × 4 × 4

∴ The volume of each cube = 64 inches³

∵ We will use 8 of this cube to make a rectangular prism

→ That means the volume of the rectangular prism is 8 times

   the volume of 1 cube

∴ The volume of the prism = 8 × volume of 1 cube

∵ The volume of each cube = 64 inches³

∴ The volume of the prism = 8 × 64

∴ The volume of the prism = 512 inches³

The volume of the rectangular prism is 512 inches³
