- 5/6x = 20

- 5 = 120x

x = - 5/120

x = - 1/24

2/3(x - 7) = - 2

2 = - 6(x - 7)

2 = - 6x + 42

6x = 42 - 2

6x = 40

x = 40/6

x = 20/3

x = 6  2/3

What is the other way to solve besides multiplying both sides by a common factor
BabaBlast [244]

Answer:

Here's one way

Step-by-step explanation:

13) multiply each term by 24

9x - 32x = 96

-23x = 96, divide both sides by -23

x = -4.17

A tourist boat is used for sightseeing in a nearby river. The boat travels 2.4 miles downstream and in the same amount of time,
topjm [15]

Answer: the current of the river is 3 mph.

Step-by-step explanation:

Let x represent the current of the river.

The boat travels 2.4 miles downstream. Assuming it travelled with the current of the river. If the boat travels at an average speed of 21 miles per hour in the still water, it means that the total speed at which the boat travelled downstream is

(21 + x) mph

Time = distance/speed

Time taken to travel downstream is

2.4/(21 + x)

it travels 1.8 miles upstream. Assuming it travelled against the current of the river. it means that the total speed at which the boat travelled upstream is

(21 - x) mph

Time taken to travel upstream is

1.8/(21 - x)

Since the time taken to travel upstream and downstream is the same, then

2.4/(21 + x) = 1.8/(21 - x)

Cross multiplying, it becomes

2.4(21 - x) = 1.8(21 + x)

50.4 - 2.4x = 37.8 + 1.8x

2.4x + 1.8x = 50.4 - 37.8

4.2x = 12.6

x = 12.6/4.2

x = 3 mph

PLEASE HELP I DO NOT UNDERSTAND AT ALL AND SHOW YOUR WORK !!
Agata [3.3K]

Answer:

y intercept (-6,0), x-intercept (0,-8) : y = \frac{-4}{3}x -8

y intercept (0,-6), x-intercept (-2,0): y = -3x -6

y intercept (0,8), x-intercept (1.6,0): y = -5x + 8

y intercept (0,7), x-intercept (-1.4,0): y = 5x + 7

Step-by-step explanation:

y = mx + b

*note: b is the y intercept

<u>1. y intercept (-6,0), x-intercept (0,-8)</u>

m = \frac{-8 - 0}{0 - (-6)}= \frac{-8}{6}  = \frac{-4}{3}\\y =  \frac{-4}{3}x + b\\y = \frac{-4}{3}x -8

<u>2.y intercept (0,-6), x-intercept (-2,0)</u>

<u />m = \frac{0 - (-6)}{-2 - 0} = \frac{6}{-2}  = -3\\y = -3x + b \\y = -3x -6<u />

<u>3. y intercept (0,8), x-intercept (1.6,0)</u>

<u />m = \frac{0 - 8}{1.6 - 0}= \frac{-8}{1.6} = -5\\y = -5x + b\\y = -5x + 8<u />

<u>4. y intercept (0,7), x-intercept (-1.4,0)</u>

<u />m = \frac{0 - 7}{-1.4 - 0} = \frac{-7}{-1.4}= 5 \\y = 5x + b\\y = 5x + 7<u />
