1 answer:

6 0

I got this. Bottom of the triangle. that flat line is 180 degrees. you have an angle of 120, leaving an angle of 60. if you look at the top, that angle matches the other. so you have 65 degrees on one side, and 60 on the other. so 180-65-60=55. so X=55

svlad2 [7]

Answer:

Step-by-step explanation:

Add 18 to both sides

16+18 = 2x

2x = 34

Divide both sides by 2

x = 34/2

x = 17

A fruit stand has 28 apples, 20 oranges, and 12 pears. What is the ratio of apples to the total pieces of fruit?

ruslelena [56]

Data:
Apples = 28
Oranges = 20
Pears = 12

What is the ratio of apples to the total pieces of fruit?
Solving:
 $\frac{apples}{apples+oranges+pears} = \frac{28}{28+20+12} = \frac{28}{60} \frac{\div4}{\div4} \to\:\boxed{\boxed{ratio = \frac{7}{15}}}\end{array}}\qquad\quad\checkmark$
