Joe’s Canoes charges an initial fee of $20 plus $4 an hour. Callie’s Canoes charges a flat rate of $14 an hour. Find the number of hours for which the total amount that both places charge would be the same.

14 hours

Step-by-step explanation:

20 + 4h = 14h

Joe's       y = 4x + 20  ($20 initial value and a rate of $4 per hr)

slope/rate is $4 per hour and the initial fee/y interceot is 20

Callie's    y = 14x (no initial fee and a flat rate if $14 per hr)

slope/rate is $14 per hour and the initial fee/y intercept is 0

Substitute in 3 for x to see who's price is better for 3 hours

y = 4(3) +20    or     y = 14(3)

y = $32                    y = $42

Callie's has the better deal for 3 hours. Only for 1 hour Joe has the better deal. At 2 hours, both are the same price, and 3 hours plus, Callie will always be cheaper.

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
