Answer:

  Erie to Rochester is 145 miles

Step-by-step explanation:

If we designate the points of interest as C, E, and R, we are told that ...

  CE + ER = CR . . . . . the various distances are segments of a straight line

For CE = 94 and CR = 239, we can fill in the given information and solve for ER.

  94 + ER = 239

  ER = 239 -94 . . . . . . subtract 94 from both sides of the equation

  ER = 145

The distance from Erie to Rochester is 145 miles.

Jane wants to go to her school's Prom Night. A ticket costs $120. Jane saved $30 months ago, however to earn
Anarel [89]

Answer:

30 + 5<em>d</em> ≥ 120

Step-by-step explanation:

One ticket costs $120 and she already has $30 saved up so the money she makes by dogwalking added to the $30 has to be equal to or greater than 120

  1. 30 for the <u>amount she saved up</u>
  2. 5<em>d</em> where <u><em>d</em></u><u> stands for the number of days she walks dogs </u>
  3. Make this information into one part of the inequality: 30+5<em>d</em>
  4. Then this has to be greater than or equal to 120 so:

<u>30+5</u><em><u>d</u></em><u>≥120</u>

Hope this helps!

2x+3=-7<br><br> What is the answer?
Mashcka [7]

Hi there! With equations like this we want to get our variable on one side and and our constant on the other.

So with 2x + 3 = -7 you'd subtract the constant 3 from both sides of the equal sign to get 2x = -10, then you'd divide both sides by 2 to get x = -5. If you double check your work by replacing x in the original equation with our answer we'd find that 2(-5) + 3 = -7 is correct.

Hope you find this helpful :)

Which of the following equations describes the line shown below? Check all that apply (-2,6) and (4,3)
avanturin [10]
A and F are true. because A is y=2x+7, and F is y=2x+7. 
We know that the equation y=2x+7 has a point 0,7 and with the slope being 2, rise over run would make another point 1,9. And because these are linear equations if the equation y=2x+7 goes through 1,9 then it will go though -2,3 as well.
