Answer:
32 muffins
Step-by-step explanation:
one cup of milk will make 32 muffins
you can set up a proportion of milk/muffins = milk/muffins
let 'x' = number of muffins made from one cup of milk
5/8 ÷ 20 = 1 ÷ x
cross-multiply to get 5x = 20(8)
5x = 160
x = 32
Answer:
3
Step-by-step explanation:
The equation being used to express the answer is called slope-intercept form.
y = m x + b
m is the slope, b is the y-intercept (where x = 0)
The formula to find slope (m) using two points is called point slope form.
m = (y1 - y2)/(x1 - x2)
Pick two coordinates and plug them in.
m = (1 - 4)/(0 - 1)
m = (-3/-1)
m = 3
Answer: The person's speed is 8 miles per hour.
Step-by-step explanation:
To solve we want to convert the
and
proportionally for the number of miles per hour. We know that multiplying a fraction by its reciprocal will equal 1. So let's do that for the value of the hour.
×
Since we multiplied that to the number of hours we must also do that for the number of miles.
×
