0.50. At the end of the night you made a total of $78.50. You sold a total of 87 hot dogs and sodas combined. You must report the number of hot dogs we're sold and how many sodas were sold?

Answer:

sorry it took awhile. 35 hot dogs were sold and 52 sodas were sold. Hotdogs in total were 35*1.50=52.5

sodas were 52*0.50=26

add 52.5+26=78.5

Step-by-step explanation:

to clarify its the answer add 35 and 52 and you will get 87 which was supposed to be the amount sold

How to determine the smallest absolute value
alexandr1967 [171]
The absolute value is basically the distance from zero, and distance is ALWAYS positive. After you removed your negatives, you need to just compare the values. For example. The smallest absolute value between -27 and 19 is 19. Hope this helped!

Answer:

The x-intercept is 2.

Step-by-step explanation:

2 \sqrt[3]{x - 10}  + 4 = 0

2 \sqrt[3]{x - 10}  =  - 4

\sqrt[3]{x - 10 }  =  - 2

x - 10 =  - 8

x = 2

Which of these describes the equation –18x + 9y = –416?
Minchanka [31]

Answer:

We conclude the equation is linear because it can be rewritten in the form y = mx + b.

Hence, option D is correct.

Step-by-step explanation:

The slope-intercept form of the line or linear equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

<u>Important Tip:</u>

The graph of a linear equation is always a straight line.

Convert the given equation in the slope-intercept form

18x + 9y = -416

subtract 18x from both sides

18x+9y-18x = - 18x-416

simplify

9y = -18x - 416

divide both sides by 9

y=-2x-\frac{416}{9}

Now, comparing the equation y=-2x-\frac{416}{9} with a slop-intercept form of linear equation

  • The slope m = -2
  • The y-intercept b = -416/9

Therefore, we conclude the equation is linear because it can be rewritten in the form y = mx + b.

From the attached graph, is also clear that the graph of the equation y=-2x-\frac{416}{9} is a straight line.

Hence, option D is correct.
