Morgan made a mistake when subtracting the rational expressions below.

Nat2105 [25]

Answer : D

$\frac{3t^2-4t+1}{t+3} - \frac{t^2+2t+2}{t+3}$

The denominators are same

So we combine the numerators

$\frac{(3t^2-4t+1)-(t^2+2t+2)}{t+3}$

To remove parenthesis we distribute negative sign inside the second parenthesis

$\frac{3t^2-4t+1-t^2-2t-2)}{t+3}$

$\frac{2t^2-6t-1)}{t+3}$

Morgan made a mistake. He forgot to distribute the negative sign

Morgan forgot to distribute the negative sign to two of the terms 2t and 2 inside second parenthesis

The price of a computer was decreased by 30% to £147. What was the price before the decrease?

Sunny_sXe [5.5K]

Answer:

£210

Step-by-step explanation:

A decrease of 30% represents 70% of the original cost.

100% represents the original cost

Divide the price by 70 to find 1% then multiply by 100 for original cost

original cost = $\frac{147}{70}$ × 100 = 2.1 × 100 = £210
