Choose the expression that would equal the number of hours in the following question.

1 answer:

5 0

<span>B. 285/302. This is the correct answer because it is the only choice which is roughly the same ratio as 47.5/50.5 which is the ratio needed to determine how long it would take to go 47 1/2 miles in a car that averages 50 1/2 miles per hour. The mathematical equation which represents the problem is: 50.5/1 = 47.5/A (A = hours) which is the same as 50.5 A = 47.5 which means A = 47.5/50.5 which means A = .94 hours. 285/302 also equals .94.</span>

Express each equation in slope-intercept form. -2x+4y=68, 13x+4y=284

lara31 [8.8K]

To get the answer we have to tranform into y=ax+b form
-2x+4y=68 /+2x
4y=2x+68 /:4
y= $\frac{1}{2} x+17$ - its the result

13x+4y=284 /-13x
4y=-13x+284 /:4
y= $- \frac{13}{4}+ 71$
y=- $3 \frac{1}{4}x+71$ - its the result

<h2>Answer: x = 6</h2>

* = things that have changed or are being changed

<h2>Explanation:</h2>

1. rearrange terms

*4 4 + 3 * = 5 + 2 + 2 0

*3x + 44* = 5x + 2 + 20

2. combine like terms

3 + 44 = *5x + 2* + 20

3 + 44 = *7x* + 20

3. Subtract 4 4 from both sides of the equation

3x + 44 = 7x + 20

3x + 44 *-44* = 7x + 20 *-44*

4. Simplify

(Subtract the numbers)

3x + *44 - 44* = 7x + 20 - 44

3x = 7x + 20 - 44

(Again)

3x = 7x + 20 *- 44*

3x = 7x - 24

5. Subtract 7 from both sides of the equation

3x = 7x - 24

3x *- 7x* = 7x - 24 *- 7x*

6. Combine like terms

*3x - 7x* = 7x - 24 - 7x

*-4x* = 7x - 24 - 7x

(Again)

-4x = *7x* - 24 *- 7x*

-4x = - 24

7. Divide both sides of the equation by the same term

-4x = - 24

$\frac{-4x}{*-4*} = \frac{-24}{*-4*}$

8. Simplify

(Cancel terms that are in both the numerator and denominator)

$* \frac{-4x}{-4} * = \frac{-24}{-4}$

*x* = $\frac{-24}{-4}$

(Divide the numbers)

x = $\frac{-24}{-4}$

x = 6
