Solve for x if 2/3x = 10
a. 20/3
b. 15
c. 9 2/3
d. 10 1/3​

The answer should be B.15

The first triangle’s area is 48.75. But since you round it to the nearest tenth, it’s 48.7.

Use the formula a=1/2bh to find the area of a triangle.
A= 1/2• 13 • 7.5
A= 6.5• 7.5
A= 48.75 —-> 48.7 square inches.

Sorry, I can only do one because of homework, but make sure to use that formula! Hope this helped.
