Answer:

The answer is B) 1.

Step-by-step explanation:

Combine the equations like this:

2x+3y=\frac{2}{3}x-1

Then subtract 3y from all sides.

2x+3y-3y=\frac{2}{3}x-1-3y

Simplify the equation.

2x=\frac{2}{3}x-1-3y

Then subtract \frac{2}{3}x from all sides.

2x-\frac{2}{3}x=\frac{2}{3}x-1-3y-\frac{2}{3}x

Simplify again.

\frac{4}{3}x=-1-3y

Multiply all sides by 3.

3\times \frac{4}{3}x=-3\times 1-3 \times 3y

Simplify again.

4x=-3-9y

Divide all sides by 4

\frac{4x}{4}=- \frac{3}{4}- \frac{9y}{4}

Simplify again.

x= \mathbf{\frac{-3-9y}{4}}

kolezko [41]

The 5.25 m combined height of John, Jim, and Joe, the 12 cm height difference between John and Jim and the 0.09 m difference in height between Jim and Joe, indicates that solution to the word problem is Joe was 1.73  meters tall

<h3>What is a word problem?</h3>

A word problem is a presentation of a math problem using verbal description rather than numbers, variables and operators.

The combined height of John, Jim and Joe = 5.25 m

John's height = Jim's height - 12 cm = Jim's height - 0.12

Jim's height = Joe's height + 0.09 m

Let <em>h </em>represent Joe's height, we get;

Jim's height = h + 0.09

John's height = h + 0.09 - 0.12 = h - 0.03

John's height = h - 0.03

The sum of the heights is therefore; h + h + 0.09 + h - 0.03 = 3·h + 0.06

The sum of their heights = Their combined height = 5.25 meters

Therefore; 3·h + 0.06 = 5.25

h = (5.25 - 0.06)/3 = 1.73

Joe's height, <em>h</em> = 1.73 meters

Jim's height = 1.73 + 0.09 = 1.82

Jim's height = 1.82 meters

John's height = 1.73 - 0.03 = 1.7

John's height is 1.7 meters

Joe was 1,73 meters tall
