Answer:
35 pounds of tea for 80 cents.
Step-by-step explanation:
Equation::
value + value = value
80x + 60(50-x) = 74*50
80x + 60*50 - 60x = 74*50
20x = 14*50
x = 35 lbs (amt. of 80 cent tea to use)
50-x = 15 lbs (amt. of 60 cent tean to use)
M = (y2-y1)/(x2 -x1)
m = (7 -2)/(5 - 1)
m = 5/4
answer: slope m = 5/4
About 18 inches / 1 foot and 6 inches
If hair grows about 6 inches every year, and we want to find out how much will grow in 3 years, we multiply.
6 x 3 = 18 inches
Then we can simplify it because there are 12 inches in a foot
18/12 = 1 6/12
