Which expressions are equivalent to 35+30s-45t?

Rainbow [258]

Answer:

B and C

Step-by-step explanation:

5 * (7 + 6s - 9t) = 7*5 + 6s *5 - 9t*5

= 35 + 30s - 45t

(-35 - 30s + 45t)*(-1) = (-35)*(-1) - 30s *(-1) + 45t*(-1)

= 35 + 30s - 45t

The percent of working students increased 21.7% to 8.9%, what was the percent prior to increase

blagie [28]

Answer:

Approximately 7.3%.

Step-by-step explanation:

What is percentage increase?

$\displaystyle \text{Percentage Increase} = \frac{\text{Final Value} - \text{Initial Value}}{\text{Initial Value}} \times 100\%$ .

For this question:

$\text{Percentage Increase} = 21.7\%$ ,
$\text{Final Value} = 8.9\% = 0.089$ , and
$\text{Initial Value}$ needs to be found.

Let $\text{Initial Value} = x$ .

$\displaystyle \frac{0.089 - x}{x} = 0.217$ .

Assume that $x \ne 0$ . Multiply both sides of the equation by $x$ :

$0.089 - x = 0.217x$ .

Add $x$ to both sides of the equation:

$0.089 = (1 + 0.217)x$ .

$\displaystyle x = \frac{0.089}{1 + 0.217} = 0.0731 \approx 7.3\%$ .

In other words, the initial percentage is approximately 7.3%.
