Answer:

x=2

Step-by-step explanation:

2x+5(3x-4)=14

Distribute

2x + 15x -20 = 14

Combine like terms

17x -20 = 14

Add 20 to each side

17x-20+20 =14+20

17x = 34

Divide by 17

17x/17 = 34/17

x=2

Answer:

x=2

Step-by-step explanation:

2x+5(3x-4)=14

distribute 5 into (3x-4)

2x+15x-20=14

combine like terms

17x-20=14

add -20 on both sides

17x=34

divide both sides by 17

$\frac{17x}{17} =\frac{34}{17}$

x=2

hope this helps

The area of a mirror is 225 square inches, and its width is 13 3/4 inches. Will the mirror fit in a space that is 15 inches by 1

gavmur [86]

If you multiply length times width to get area, it's the same with division. You do area divided by length or width. The equation would be 225 divided by 13 3/4. 225/13 3/4= 16.36 inches. 16.36 > 16 inches, so the answer would be no. (The mirrors length and width are 13 3/4 inches by 16 9/25)

Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly trav

ivann1987 [24]

Answer:

<h2>The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.</h2>

Step-by-step explanation:

According to the graph, the dependent variable is Distance in miles, because it's on the vertical axis. Additionally, the independent variable is time in hours, because it's on the horizontal axis. However, you always put time as independent, because nothing affects time.

To find the equation, we just need to find the slope, using two points (0,0) and (2,40).

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{40-0}{2-0}=20$
