Moving to another question will save this response. Question 9
Charlie paid $168 for 12 tickets (3 adults and 9 children) to visit a theme park,
If A represents the cost of an Adult ticket and represents the cost of a child ticket, write an algebraic equation to express A in terms of
Observe algebraic convention, your answer should be a simplified equation, do not use brackets or units in your equation hint: make sure you remove any common factors from
If an adult ticket costs $20, use this information and your equation to find the cost of a child ticket
Your answer should be a numerical value to the nearest whole number, including units:
C8

step-by-step explanation:

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
