At work, Elon takes a break 1/5 of each hour he works. He also takes a lunch break for 1/2 of an hour each day he works. Elo

Anton [14]

Answer:

$h=50\ hours$

Step-by-step explanation:

Let

h -----> the number of hours, Elon works during one 5-day work week

we know that

$12\frac{1}{2}\ h=\frac{12*2+1}{2}=\frac{25}{2}\ h$

Elon’s break time must be equal to 1/2 of an hour multiplied by 5 days plus 1/5 multiplied by the total hours h

so

$\frac{25}{2}=5(\frac{1}{2})+\frac{1}{5}h$

Solve for h

Multiply by 10 both sides to remove the fraction

$125=25+2h$

$2h=125-25$

$2h=100$

$h=50\ hours$

When 4 is added to three times of a number, the answer is the same as subtracting 2 from the number. What is the number ?

Orlov [11]

Answer:

- 3

Step-by-step explanation:

let n be the number , then

3n + 4 = n - 2 ( subtract n from both sides )

2n + 4 = - 2 ( subtract 4 from both sides )

2n = - 6 ( divide both sides by 2 )

n = - 3

The number is - 3

Five times the sum of one-half and a number

yawa3891 [41]

5( $\frac{1}{2}$ + x) would be your answer. The 5 and the parenthesis imply multiplication, and inside the parenthesis is one-half and a number being added.)
