1. 9%

2. 0.45

3. 98.5%

4. 80%

5. Decimal: 0.15, Fraction:

Step-by-step explanation:

When calculating percentage, turn the question to a fraction and multiply the fraction by 100%.

When calculating decimal, turn the question to a fraction out of 100, and turn it into a decimal.

When calculating a fraction in its simplest form, turn the question to a fraction and simplify it.

1. (Percentage)

Fraction:

Percentage: × 100% = 9%

2. (Decimal)

Fraction:

Decimal: 45 ÷ 100 = 0.45

3. (Percentage)

Fraction: 0.985 =

Percentage: × 100% = 98.5%

4. (Percentage)

Fraction:

Percentage: × 100% = 80%

5. (Decimal)

Fraction: 15% =

Decimal: 15 ÷ 100 = 0.15

5. (Fraction)

Fraction:

Simplest form: = (Divide both numerators and denominators by 5)

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
