Answer:

x = -1

y = 2

Step-by-step explanation:

y = x+3

x+2y = 3

substitute y

x+2(x+3) = 3

simplify

3x+6 = 3

subtract 6 from both sides

3x = -3

x = -1

y = -1+3 = 2

Saqui buys streamers for \$0.09$0.09dollar sign, 0, point, 09 per meter.
Colt1911 [192]

Answer:

$0.27

Step-by-step explanation:

1/4 The ratio of meters of streamers to cost of streamers is 1 : 0.09

     We want to know the ratio of centimeters of streamers to cost of  
     streamers.

2/4 We need to convert meters to centimeters.

      There are 100 centimeters in 1 meter.

      So, if 1 meter of streamers costs $0.09, then 100 centimeters of
      streamers also cost $0.09.

3/4 The ratio centimeters of streamers to cost for 300 centimeters of
      streamers.

      Now, we can find an equivalent ratio to find the cost for 300
      centimeters of streamers.

4/4 The streamers cost $0.27 per 300 centimeters.
