Answer:

That's correct lol

Step-by-step explanation:

Basically the equation was multiplied by the same fraction on both sides 1/2 * 2 = 2/2 = 1 = x

On the other side of the equation the same was done:

1/2 * 8 = 8/2 = 8 ÷ 2 = 4

Now we have x = 4 and it makes perfect sense.

Hope this helped!

Hey You!

You know 27 is closer to 30 because the number is above 25, and it would take 7 blocks to get closer to 20 and only 3 to 30.

Abdul is creating a cushion that is 1 foot by 2 feet by 3 feet. He wants to find the least amount of fabric he will need to cove

Answer:

The least amount of fabric are 22 square feet

Step-by-step explanation:

we know that

The surface area of a rectangular prism is given by the formula

$SA=2B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

Let

L ---> the length pf the prism

W ---> the width of the prism

H ---> is the height of the prism

Let

$L=2\ ft\\W=3\ ft\\H=1\ ft$

Find the area of the base

$B=LW=(2)(3)=6\ ft^2$

Find the perimeter of the base

$P=2(L+W)=2(2+3)=10\ ft$

Find the surface area

$SA=2(6)+10(1)=22\ ft^2$

therefore

The least amount of fabric are 22 square feet

What is the solution to the inequality x+(7+2x)<-3x

Karo-lina-s [1.5K]

$Solution, x+7+2x$

$Steps:$

$x+7+2x$

$\mathrm{Group\:like\:terms}, x+2x+7$

$\mathrm{Add\:similar\:elements:}\:x+2x=3x, 3x+7$

$\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides}, 3x+7-7$

$\mathrm{Simplify}, 3x$

$\mathrm{Add\:}3x\mathrm{\:to\:both\:sides}, 3x+3x$

$\mathrm{Simplify}, 6x$

$\mathrm{Divide\:both\:sides\:by\:}6, \frac{6x}{6}$

$\mathrm{Simplify}, x$

$\mathrm{The\:Correct\:Answer\:is\:x$
