Answer:

Multiple the first equation by -1

Step-by-step explanation:

After doing this you add the two equations together and follow the systems of equations as normal

-3x+-5y=-16\\3x+2y=10\\-3y=-6\\\frac{-3y}{-3} =\frac{-6}{-3} \\y=2

Therefore y = 2

aleksley [76]

To find k, divide both sides by 1/4

K = 2/3 / 1/4

When dividing by a fraction flip the second fraction over then multiply:

K = 2/3 x 4/1 = (2 x 4) / (3 x 1) = 8/3

K = 8/3 = 2 and 2/3

Please solve number 11:(​
MrRa [10]

Answer:

Market price $400

Cost price $300

Step-by-step explanation:

MP: market price

CP: cost price

1. (MP x 0.9) - CP = 60

CP = 0.9MP - 60

2. MP - CP = 100

CP = MP - 100

0.9MP - 60 = MP - 100

MP - 0.9MP = 100 - 60

0.1MP = 40

MP = 400

Cost price = MP - 100 = 400 - 100 = 300
