x=2

1:Subtract 2x from both sides.

2:Combine 2/3 x and -2x to get -4/3

3:Subtract 3/8 from both sides. Anything subtracted from zero gives its negation.

4:Multiply both sides by -3/4,the reciprocal of -4/3

5:Multiply − 3/8 ​ times − 4/ 3 ​ by multiplying numerator times numerator and denominator times denominator.

6:Do the multiplications in the fraction −8(−3) over 3x4.

x=24/12

Divide 24 by 12 to get 2.

x=2

Hong reads 9 3/4 chapters in 3 3/8 hours. What is the unit rate in chapters per hour? Write your answer as a fraction or a mixed
Sav [38]

The unit rate is: 2\frac{8}{9} chapters per hour

Step-by-step explanation:

Given

chapters read = 9\frac{3}{4} = \frac{39}{4}

Time = 3\frac{3}{8} = \frac{27}{8}

Unit rate is calculated by dividing the total chapters by total time

So,

Unit\ rate = \frac{\frac{39}{4}}{\frac{27}{8}}\\= \frac{39}{4} * \frac{8}{27}\\= 13 * \frac{2}{9}\\=\frac{26}{9}\\=2\frac{8}{9}

Hence,

The unit rate is: 2\frac{8}{9} chapters per hour

10. A parallelogram is a rectangle if the sides are perpendicular. The slopes of the short sides are rise/run = -1, and the slopes of the long sides are rise/run = +1. These values have a product of -1, so the sides are perpendicular. The figure is a rectangle.
