First, we have to figure out how much cheese we have total. Do this by adding up all of the various cheeses.

\frac{2}{3}  +  \frac{4}{3}  +  \frac{5}{4} \\  \frac{6}{3}  + 1 +  \frac{1}{4}  \\ 3 \frac{1}{4}
Now to split the cheeses into sections of 1/4 pound each, we have to divide by 1/4, which is the same as multipling by 4

3 \frac{1}{4}  \times 4 = 12 + 1 = 13

13 slices total

Solve The Linear Equation for the stated variable.
larisa [96]

Answer:

m=\frac{g}{4c-3}

Step-by-step explanation:

we have

g=4cm-3m

Solve for m

That means-----> isolate the variable m

Factor the variable m in the equation

g=m[4c-3]

Divide by (4c-3) both sides

\frac{g}{4c-3}=m

Rewrite

m=\frac{g}{4c-3}

According to the US department of labor, total employment is expected to increase from 146 million in 2000 to 168 million in 201
saveliy_v [14]

Answer:

The percent increase in the employment from the year 2000 to year 2010 is 15.07\%.

Step-by-step explanation:

Given:

Employment in the year 2000 =146 million.

Employment in the year 2010 =168 million.

To find: The percent increase in the employment.

Solution: We have,

Employment in the year 2000 =146 million.

Employment in the year 2010 =168 million.

Increase in employment =168-146=22 million.

Percent increase =\frac{\textrm{Increase in employment}}{\textrm{Original employment}}\times100\%

Percent increase =\frac{22}{146}\times100\%=15.07\%

Hence, the percent increase in the employment from the year 2000 to year 2010 is 15.07\%.
