Jasmine is in charge purchasing tubes of silicone sealant, used for finishing restroom facilities. She finds that she is able to
Georgia [21]

The question attached is:

Is Jasmine correct about the silicone sealant cones?

If you think Jasmine is correct to explain, why.

Answer:

Jasmine is correct about the silicone sealant cones

Step-by-step explanation:

Given that:

Jumbo cone of sealant has a top diameter of 12 inches and a height of 14 inches, Suppose Jasmine orders or demands for two regular cones of regular sealant, definitely, that will be equal to the Jumbo cone of sealant.

This is because the top diameter when put together in a Jumbo cone will give an actual result as a Jumbo cone, for as much as 6 × 2 = 12 inches (top diameter) and 7 × 2 = 14 inches (height).

How could you solve for x in the problem 3x+7=-x-1
lukranit [14]

Hello there!

3x+7=-x-1\\

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by 7 from both sides of the equation.

3x+7-7=-x-1-7

Simplify

3x=-x-8

Then you add by x from both sides of the equation.

3x+x=-x-8+x

Simplify

4x=-8

Divide by 4 from both sides of the equation.

\frac{4x}{4}=\frac{-8}{4}

Simplify it should be the correct answer.

x=-2

Answer⇒⇒⇒x=-2

Hope this helps!

Thank you for posting your question at here on Brainly.

Have a great day!
