A car travels 350 miles on 20 gallons of gas how many gallons will be used to travel 875 miles

tino4ka555 [31]

Hi there! You will need to do a unit rate, so you would do 20/ 350 which is a weird number 0.05714285714 , and then you multiply 0.057142857148 * 875= 50 gallons. So for 875 miles you will need 50 gallons of gas.

The line representing a proportional relationship always goes through the point (0,0). If x is zero, multiplying x by the consta

Sidana [21]

Answer:

B (2, 4)

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 $k=\frac{y}{x}$ or $y=kx$

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

In this problem the constant of proportionality k is given and is equal to

$k=2$

The linear equation is given by

$y=2x$

That means ----> the y-coordinate is two times the x-coordinate

therefore

The other point is B(2.4)

Because

For x=2, y=4

the y-coordinate is two times the x-coordinate

$4=2(2)\\4=4$

Part E 1e. Subtract the binomial 12y2 – 4y3 from the trinomial 7y - 2y3 + 5y2

bazaltina [42]

Answer:

2y^3-7y^2+7y

Step-by-step explanation:

7y - 2y^3 + 5y^2 - ( 12y^2 – 4y^3)

Distribute the minus sign

7y - 2y^3 + 5y^2 - 12y^2 + 4y^3

Combine like terms

2y^3-7y^2+7y
