A local baseball team about 75 shirts from the T-shirt company. The team was charged $6.25 for total shipping but received a $20
ollegr [7]
In order to solve this question
Make an equation
Let x be the cost of each T- shirt
75x+6.25-20=398.75
Simplify the equation
75x-13.75= 398.75
Get Rid of The Constant
75x-13.75+13.75= 398.75+13.75
75x=412.5
Make sure your Variable is equal to one
75x÷75= 412.5÷75
x= 5.5
The price of each shirt is $5.50

David is driving on the highway. He begins the trip with 14 gallons of gas in his car. The car uses up one gallon of gas every 2
ehidna [41]

Answer:

G = -D/20 + 14

Graph in the image attached.

Step-by-step explanation:

Using the model of a linear equation, we have:

G = aD + b

'b' is the y-intercept of the equation, that is, the inicial value of G, when D = 0.

So if David starts the trip with 14 gallons of gas, we have b = 14.

'a' is the slope of the line, that is, an increase of 1 in the value of D causes an increase of 'a' in the value of G.

So if the car uses one gallon every 20 miles, the value of a is -1/20 (an increase of 20 in D causes a decrease of 1 in G).]

So our equation is:

G = -D/20 + 14

The graph of this equation is in the image attached.

What is the solution of the system of equations? Show your work.
scZoUnD [109]

Answer:

1.Solve for y in 2x+y=-3

y=-3-2x

2. Substitute y= -3 - 2x into 4x-2y=10

8x+6=10

3 Solve for x in 8x+6=10

x=1/2

​

4. Substitute x=1/2 into y = - 3 - 2x

y= -4

5. So you get...,

x=1/2

y=−4

​

Step-by-step explanation:

you're welcome :)
