Assuming you want to solve for x:

Make 15x and 15 add up to 180 in an equation since they form a straight line. A straight line is 180 degrees.

15x + 15 = 180

  • Subtract 15 from both sides.

15x = 165

  • Divide both sides by 15.

x = 11

15 + 15 + 15x + 15x = 180

30 + 30x = 180

30x = 150

x = 5

Nancy put 80 acorns in her backyard. Then, she made a graph of how many acorns different types of squirrels
Karolina [17]

Answer:

  16

Step-by-step explanation:

If we take the partial image to be 1/2 of a full image, then there are a total of

  5 1/2 + 2 + 6 + 2 1/2 = 16

acorn images on the graph. Each image represents 4 acorns, so a total of ...

  4 × 16 = 64

acorns are represented on the graph. Since these are ones the squirrels ate, the remaining 80 -64 = 16 acorns were left uneaten.
