Answer:
8
Step-by-step explanation:
When you divide by a fraction, you can also say that you are multiplying by the reciprocal.
So 
30/150 = 80/x
Reduce the fraction:
1/5 = 80/x
Cross multiply:
x = 5 x 80
x= 400

Answer:
7 7/12 pounds of fruit
Step-by-step explanation:
First, add all of the whole numbers
2 + 1 + 3= 6 (save for later)
then find a common denominator between the fractions which is 12
1/3 = 4/12
5/6 = 10/12
4/12 + 10/12 + 5/12 = 19/12 or 1 7/12
now, add 1 7/12 + 6 to get you 7 7/12
hope this helps
Answer:
92
Step-by-step explanation:
angle a and b add up to 180 degrees
4x-20+2x+8=180
add like terms
6x+12=180
x=28
then substitute to get 92
The range is Max - Min = 299 - 0 = 299
Divide this range over 10 to get 299/10 = 29.9 which rounds to 30
We'll need about 30 intervals if we want intervals of width 10
