Use the subtraction method to solve the system of equations. Choose the correct ordered pair. 2x-y=6
Ber [7]

Answer:

Check for (3, 0)

Put x = 3 and y = 0 in equation 2x – y = 6

2(3) – (0) = 6

6 = 6

<h2>True statement. </h2>

(3,0) is a solution of 2x – y = 6.

(ii) Check for (0, 6)

Put x = 0 and y = 6 in 2x – y = 6

2 x 0 – 6 = 6-6 = 6

<h2>False statement. </h2>

⇒ (0, 6) is not a solution of 2x – y = 6.

(iii) Check for (2, -2)

Put x = 0 and y = 6 in 2x – y = 6

2 x 2 – (-2) = 6

4 + 2 = 6

6 = 6

<h2>True statement. </h2>

⇒ (2,-2) is a solution of 2x – y = 6.

(iv) Check for (√3, 0)

Put x = √3 and y = 0 in 2x – y = 6

2 x √3 – 0 = 6

2√3 = 6

<h2>False statement. </h2>

⇒(√3, 0) is not a solution of 2x – y = 6.

(v) Check for (1/2, -5)

Put x = 1/2 and y = -5 in 2x – y = 6

2 x (1/2) – (-5) = 6

1 + 5 = 6

6 = 6

<h2>True statement. </h2>

⇒ (1/2, -5) is a solution of 2x – y = 6.

At a bargain store, Tanya bought 3 items that each cost the same amount. Tony bought 4 items that each cost the same amount., bu
TEA [102]

Answer: Let x represent the cost of one of Tanya's items.

Then the cost of one of Tony's items =x - 2.25. But we have:

3x =4(x - 2.25)

3x =4x - 9 subtract 3x from both sides

0 =x - 9 add 9 to both sides

x=$9 The cost of one of Tanya's items

27 Total cost of Tanya's 3 items

2.25 =$6.75 cost of one of Tony's items.

27 Total cost of Tony's 4 items.

3 x 6.75 =$27. This shows that both Tony and Tanya spent the same amount of money.

Keisha is babysitting at $8 per hour to earn money for a car. So far she has saved $1300. The car that Keisha wants to buy costs
11Alexandr11 [23.1K]

Answer:

$4100

Step-by-step explanation:

For Kaisha to get this car we have these information available

Amount saved = $1300

The cost of the car = $5400

Let The amount left to complete the car = k

We have this equation

K + $1300 = $5400

K = 5400 - 1300

K = 4100

Therefore Kaisha still needs to earn an additional amount of $4100 for the total amount of the car to be completed.
