Answer:

14= -2s - 8

22= -2s

-11=s

Step-by-step explanation:

Add 8 to both sides, on one sided the number will be undo but on the other it won't

Then divide both sides by -, wich leaves the unknown variable alone

Finally you have your answer!

Solve for X 3(x + 7) < 7(x + 2)

Furkat [3]

Answer:

x > 7/4

Step-by-step explanation:

3(x + 7) < 7(x + 2)

Expand brackets: 3x + 21 < 7x + 14

Subtract 14 from both sides: 3x +7 < 7x

Subtract 3x from both sides: 7 < 4x

Divide both sides by 4: 7/4 < x

Therefore x > 7/4

Mr. Erickson will be living in the forest

aliina [53]

$\huge{\boxed{60\ \text{ft}^{3}}}$

We will assume the tent is in the shape of a triangular prism.

The volume of a triangular prism can be found with the following formula, where $b$ is the width at the base, $h$ is the height, and $l$ is the length.

$V=\frac{1}{2}bhl$

Substitute in the known values.

$V=\frac{1}{2}*5*3*8$

Simplify — use multiplication.

$V=\frac{5}{2}*3*8$

$V=\frac{15}{2}*8$

$V=\frac{120}{2}$

Simplify — use division.

$V=\large{\boxed{60\ \text{ft}^{3}}}$

The volume — or in this case, the amount of living space — is $60\ \text{cubic feet}$ .

Evaluate 7(-4) - |-6| + |4| A. 13 B.-18 C. -30

tester [92]

Hello there!

Answer: ⇒ C. -30

_________________________________________________________

Step-by-step explanation:

First you had to remove parenthesis.

$-7*4-|-6|+|4|$

Then you multiply by the number.

$=-28-|-6|+|4|$

Apply absolute value.

$|-6|=6$

$=-28-6+|4|$

Again apply absolute value.

$|4|=4$

$=-28-6+4$

Simplify it's should be the correct answer.

$=-30$

Please please help............

Part A Simplify:

Answer is - 12b + 6c + 18

Part B

Answer is (D)

Factor/simplify
- 12b + 6c + 18

6(- 2b + c + 3)
= (6)(- 2b + c + 3)
= (6)(- 2b ) + (6)(c) + (6)(3)
= - 12b + 6c + 18

therefore,- 12b + 6c + 18; Factored in GCF is 6(-2b + c + 3)

- 12b + 6c + 18
reorder the terms
18 + 12b + 6c

Factor out the GCF " 6"
6(3 + 2b + c)

Final Result:
6(3 + 2b + c)

Hope this helps
