Answer:

x=3

Step-by-step explanation:

1) 3(x+7)=6(x+2)

2)Multiply the number on the outside by the numbers on the inside

3x+21 =6x+12

3)Subtract 3x from 6x. When you do that it cancels out itself on the side it came from leaving you with only 21 one that side.

21=3x+12

4)Subtract 12 from 21. When you do that it cancels out itself on the side it came from leaving you with only 3x on that side.

9=3x

5) Divide 3x from both sides that will cancel out the x leaving you with only 1x and it will turn the 9 into 3.

9/3x=3x/3x

x=3

$8000 at 3% annually for 4 years

Nonamiya [84]

Here's the equation for one year:
0.03(8000) + 8000
For four years:
4(0.03(8000)) + 8000
0.12(8000) + 8000
To make it simpler/smaller:
1.12(8000) = 8960
You can make 960 more dollars, and you now have $8960

Leah loves chicken wings and is comparing the deals at three different restaurants. Buffalo Bills has 88 wings for \$7$7. Buffal

Ksivusya [100]

Answer:

Buffalo mild wings offers the lowest price per wing ($0.83).

Step-by-step explanation:

Let us find unit price per buffalo wing of each restaurant.

$\text{Unit rate for buffalo bills}=\frac{\$7}{8\text{ wings}}$

$\text{Unit rate for buffalo bills}=\frac{\$0.875}{\text{ wing}}$

Upon rounding our answer to nearest cent we will get,

$\text{Unit rate for buffalo bills}=\frac{\$0.88}{\text{ wing}}$

Therefore, buffalo bills offers each wing for $0.88.

$\text{Unit rate for buffalo mild wings}=\frac{\$10}{12\text{ wings}}$

$\text{Unit rate for buffalo mild wings}=\frac{\$0.83333}{\text{ wing}}$

Upon rounding our answer to nearest cent we will get,

$\text{Unit rate for buffalo mild wings}=\frac{\$0.83}{\text{ wing}}$

Therefore, buffalo mild wings offers each wing for $0.83.

$\text{Unit rate for wingers}=\frac{\$17}{20\text{ wings}}$

$\text{Unit rate for wingers}=\frac{\$0.85}{\text{ wing}}$

Therefore, wingers offers each wing for $0.85.

We can see that buffalo mild wings offers the lowest price per wing that is $0.83 per wing.
