Answer:

x = 1

Step-by-step explanation:

1/2x - 3/4 = 3/8 - 5/8x

The LCD is 8. Lets change every fraction to a denominator of 8.

4/8x - 6/8 = 3/8 - 5/8x

Now multiply both sides by 8.

4x - 6 = 3 - 5x

Add 5x to both sides. Add 6 to both sides.

9x = 9

Divide both sides by 9.

x = 1

Three different golfers played a different number of holes today. Rory played 9 holes and had a total of 42 strokes. Alicia play

choli [55]

Answer:

Alicia is the golfer who has had the lowest number of strokes per hole

Step-by-step explanation:

we know that

The unit rate of the number of strokes per hole is equal to divide the number of strokes by the number of holes

Let

x ----> the number of strokes

y ----> the number of holes

we have

$x=42\ strokes\\y=9\ holes$

$\frac{x}{y}=\frac{42}{9}=4.67\ strokes\ per\ hole$

<em>Alicia</em>

$x=79\ strokes\\y=18\ holes$

$\frac{x}{y}=\frac{79}{18}=4.39\ strokes\ per\ hole$

<em>Rickie</em>

$x=123\ strokes\\y=27\ holes$

$\frac{x}{y}=\frac{123}{27}=4.56\ strokes\ per\ hole$

Compare

4.39 < 4.56 < 4.67

therefore

Alicia is the golfer who has had the lowest number of strokes per hole

Find the volume of the composite figure

Nadya [2.5K]

Volume is a three-dimensional scalar quantity. The volume of the composite figure is 14 ft³.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of the composite figure is,

Volume = (1/3 ×1.5 × 2 × 2) + (2 × 1.5 × 4)

= 2 ft³ + 12 ft³

= 14 ft³

Hence, the volume of the composite figure is 14 ft³.
