Answer:

(13) Equation: x + (x+2) + 72 = 180

      Answer: x = 53

(14) B = 55 degrees

Step-by-step explanation:

(13) The sum of the angles in any triangle is always 180 degrees, so you can find the sum of the given angles and set up an equation, then solve

x + (x+2) + 72 = 180

2x + 74 = 180

2x = 106

x = 53

(14) If x = 53 and angle B is equal to to x + 2, you can just add 2 to 53 and get the answer that the measure of angle B is 55 degrees

The bakery shop purchased 7 2/10 pounds of sugar and 7 5/10 pounds of flour. How much sugar and flour did they purchase in all?​
gizmo_the_mogwai [7]

Answer:

Sugar = 1-2/5 pounds, Flour = 3-1/2 pounds

Together = 5-9/10 pounds

Step-by-step explanation:

sugar = 7(2/10)

flour = 7(5/10)

sugar + flour = 7(2/10) + 7(5/10)

sugar = 14/10 or 1-2/5 pounds

flour = 35/10 or 3-1/2 pounds

What is the graph of y = x - 3 (shown below) translated up 2 units?
Mrac [35]
I don't see a "shown below," so I'm not sure if I could accurately answer your question. However, if your graph point is (x,-3), then it wants you to move your graphed point up two units. I believe that would be y = x -1? I'm not sure
