Answer:

= 11/3

Step-by-step explanation:

1. COMBINE MULTIPLIED TERMS INTO A SINGLE FRACTION

- 7/3 (3x-2)= -21

-7 (3x-2) = -21

-----------------------

3

2. DISTRIBUTE

-7( 3x- 2) ➗ 3 =-21

3. MULTIPLY ALL TERMS BY THE SAME VALUE TO ELIMINATE FRACTION DENOMINATORS

-21x + 14 ➗ 3 = 3 (-21)

4. CANCEL MULTIPLIED TERMS THAT ARE IN THE DENOMINATOR

3 ( -21x + 14) ➗ 3 (-21)

5. MULIPLY THE NUMBERS

-21x + 14 = 3(-21)

6. SUBTRACT 14 FROM BOTH SIDES OF THE EQUATION

-21x + 14 = -63

7. SIMPLIFY

-21x = - 77

8. DIVIDE BOTH SIDES OF THE EQUATION BY THE SAME TERM

-21x/-21 = -77/-21

9. SIMPLIFY

x = 11/3

Of the 240 shirts on a rack, 40 percent are size medium. How many shirts on the rack are size medium?
vfiekz [6]

<span>First, let’s check for the given:

Shirts on the rack = 240</span>

Medium size shirts = 40% of 240

 

<span>With the following given, we can now solve for the total number of shirts on the rack that are size medium.

So, in order to solve for the problem, we multiply 40% to 240:</span>

<span>The decimal equivalent of 40% is 0.4.

240 shirts * .4 = 96 shirts</span>

Therefore, out of 240 shirts on the rack, there are 96 shirts on the rack that are size medium.

 

To add, the number or ratio that represents a fraction of 100 is called a percentage.

Given:

A car traveled 150 km in 3 hour.

To find:

The unit rate.

Solution:

We have,

Distance = 150 km

Time = 3 hours.

In this case speed is the unit rate.

Speed=\dfrac{Distance}{Time}

Substituting the given values, we get

Speed=\dfrac{150\text{ km}}{3\text{ hr}}

Speed=50\text{ km/h}

Therefore, the unit rate is 50 km/h.
