Answer:

x=9 y=45

Step-by-step explanation:

y=4x + 9.......(1)

y= 5x.........(2)

Substitute 5x for y in equation 1.

5x= 4x + 9

5x - 4x = 9 (Collect like terms 5 and 4 have x in common if +4 crossover it changes to -4)

x = 9

substitute 9 for x in equation 2.

y = 5(9)

y = 5 x 9(multiplication)

y = 45

<em><u>Step One</u></em>

Find the prime factors of 18 and 20

18:3*3*2

20: 2 * 2 * 5

<em><u>Step Two</u></em>

You need two 2s two 3s and one 5 for the common denominator

<em><u>Step Three</u></em>

Put the two fractions over 180

\dfrac{17*10}{10*18} + \dfrac{1*9}{10*18}

\dfrac{170}{180} + \dfrac{9}{180}

polet [3.4K]

Answer:

Belinda's score is 32 strokes.

Step-by-step explanation:

Let the score of John be "x" and Belinda be "y".

It is given that, in the game of golf, John's score was 10 less than two times Belinda's score.

Also, John's score is 54 strokes.

The above equation can be written as ;

x = 2(y) -10

Here, x = 54,

54 = 2(y) -10

64 = 2(y)

y = 32

Thus, Belinda's score is 32 strokes.
