Problem #3 Carlo and Angie will be attending the same four-year college 10 points next year. -Both will pay about $42,000 in tuition and fees -Carlo will live
on-campus and pay $12,000 room and board -Angie will live at home for
free -Carlo has received an $18,000 athletic scholarship -Angie has
received a $5,000 grant for academic achievement *
Angie will pay $49,000
Carlo will pay $72,000
Carlo will pay $13,000 less than Angie
Angie will pay $1,000 more than Carlo

50-38=12

step-by-step explanation:

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
