Answer:

x = 3, y = - 2

Step-by-step explanation:

By substitution method,

4x + y = 10 -------> equation 1.

7x + 2y = 17 -------> equation 2.

From equation 1,

y = 10 - 4x ------> equation 3.

Substitute equation 3 in 2,

7x + 2 ( 10 - 4x ) = 17

7x + 20 - 8x = 17

7x - 8x = 17 - 20

- x = - 3

x = 3

Substitute x = 3 in equation 1,

4 ( 3 ) + y = 10

12 + y = 10

y = 10 - 12

y = - 2

Hence,

x = 3

y = - 2

The Rangers won five of the first six games. how many of the next 30 games must the rangers wins have twice as many wins as loss
barxatty [35]

Using proportions, it is found that they must win 19 of their next 30 games.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

We want a win-to-loss proportion of 2:1, which is equivalent to a win-to-total proportion of 2:3. We have that:

  • The team will have won 5 + x games.
  • The team will have played 36 games.

Hence:

\frac{5 + x}{36} = \frac{2}{3}

3(5 + x) = 72

15 + 3x = 72

3x = 57

x = 19.

The Rangers must win 19 of their next 30 games.

4(x−5) <br> 2<br> =36<br><br> can i please get an answer to this
Nutka1998 [239]

Answer:

19/2 or 9.5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(x−5)(2)=36

8x+−40=36(Distribute)

8x−40=36

Step 2: Add 40 to both sides.

8x−40+40=36+40

8x=76

Step 3: Divide both sides by 8.

8x/8=76/8

x=19/2
