Readme [11.4K]4 years ago
4 0

Answer:

{y,x} = {-7,-3}

Step-by-step explanation:

- 3x = 2

  y - 2x = -1

-3x + y = 2        -2x + y = -1  

y = 2x - 1

(2x-1) - 3x = 2

    - x = 3   x = - 3

y = 2x-1

   x = -3

y = 2(-3)-1 = -7

Riley and Erik have earned a total of 135 tokens to buy items in the school store. The ratio of the number of tokens that Riley
inysia [295]

There are 72 tokens with Riley and 63 tokens with Erik

<em><u>Solution:</u></em>

Riley and Erik have earned a total of 135 tokens to buy items in the school store

Total number of tokens = 135

The ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7

Number of tokens with Riley : Number of tokens with Erik = 8 : 7

Let the number of tokens with Riley be 8x

Let the number of tokens with Erik be 7x

Since, Total number of tokens = 135

number of tokens with Riley + number of tokens with Erik = 135

8x + 7x = 135

15x = 135

x = 9

Therefore,

Number of tokens with Riley = 8x = 8(9) = 72

Number of tokens with Erik = 7x = 7(9) = 63

Thus there are 72 tokens with Riley and 63 tokens with Erik
