Answer:

1.0302

Step-by-step explanation:

The multiplier for a increase of a% is 1 + a/100.

The multiplier for a decrease of b% is 1 - b/100.

2% increase:

1 + (2/100) = 1 + 0.02 = 1.02

1% increase:

1 + (1/100) = 1 + 0.01 = 1.01

What single decimal multiplier would you use to increase by 2% followed by a 1% increase?

1.02*1.01 = 1.0302

The answer is 1.0302

Solve the system: {4x-7y=30, 4x-5y=90

Lerok [7]

Answer:

x=60, y=30

Step-by-step explanation:

4x-7y=30

4x-5y=90

Subtract the equations

4x-7y=30-4x-5y=90

=2y=60

Solve 2y=60

Divide both sides by 2

2y/2=60/2

Simplify;

y=30

For 4x-7*30=30 for x

4x-7y*30=30

Multiply the numbers:7*30=210

4x-210=30

Add 210 to both sides

4x-210+210=30+210

Simplify;

4x=240

Divide both sides by 4

4x/4=240/4

Simplify

x=60

The solutions to the system of equations are:

x=60, y=30
