6 0

Answer:

Step-by-step explanation:

If y=6 and z=3, then plug in the numbers given to the variables.

3/2 times 6, -3 + 5/3 times 3.

6= 6/1, so, you can do the same operation.

3/2 times 6/1. then subtract 3 from that.( you have to simplify them to make equal denominators)

5/3 times 3/1 then add that to your previous answer.

spin [16.1K]

Answer:

(1,3)

y= 3

x= 1

Step-by-step explanation:

7x+y=10

3x-2y= -3

solve the equation

y=10-7x

3x-2y= -3

substitute the value of y into an equation

3x-2(10-7x)= -3

distribute

3x-20-14x= -3

add 14x from both sides

17x-20= -3

add 20 from both sides

17x=17

divide both sides by 17

x=1

substitute the value of x into an equation

y=10-7•1

multiply 7 to 1

y=10-7

subtract

y=3

Jack will spend a total of exactly $15 on Redbix movies and games. What equation in standard form can he use to graoh a line sho
alina1380 [7]

Answer:

1.25x+2.5y -15 = 0

Step-by-step explanation:

Total amount to be spent on Redbix movies and games = $15

Money to be paid for each movie = $1.25

Money to be paid for each game = $2.50

To find:

Equation in standard form that can be used to graph the line.

Solution:

First of all, let us learn about the standard form of equation of a line.

Standard form can be represented as:

Ax+By+C =0

Where A,B, C are constants.

Now, let us try to make equation.

Let number of movies bought = x

Amount to be paid for movies = $1.25x

Let number of movies bought = y

Amount to be paid for movies = $2.50y

Total money is $15.

Therefore, we can write the equation as:

1.25x+2.5y = 15

Standard form can be written as:

1.25x+2.5y -15 = 0
