Answer:
t = 0.53 hr
Step-by-step explanation:
We write expressions for the distances walked by these two people, sum them up and set the sum equal to 4 miles:
(3.5 mph)(t) + (4mph)(t) = 4 mi
Combining these terms:
(7.5 mph)(t) = 4 mi
4 mi
Solving for t: t = ---------------- = 0.53 hr
7.5 mph
Let's first find the number of apple pies.
apple pies = 65 crates x 43 apple pies per crate = 2795 apples pies
If each apple pie cost $12 then...
money from apple pies = 2795 apple pies x $12 = $33540
total pies sold = 2795 apple pie + 121 boxes x 76 sweet potato pies = 11991 pies
Yes. the slope is 1.5 so we agree with both of them because 6/4=1.5 and 1.5/1=1.5
Using addition
x-y+1/2x+y=1+5
x+1/2x+0y=6
3/2x=6
3x=12
x=4
Using the value of x
x-y=1
4-y=1
y=3
With x as 4 and y as 3, their product is 12
And can be written as (4,3)
