Morgarella [4.7K]
<span>Last year, Shantell bought a car for 24 000 dollars. It decreases to 21 000 dollars this current year.
Let’s find for the percentage that it decreased.
=> in 24 000 the 50% is 12 000 as we all know since it’s divided by 2. So meaning, the possible answer is less than 50%.
=> now 25% of 24 000 is 6 000, and the amount that we’re looking is 3000, thus, the answer is 12.5%
=> 24 000 * 0.125 = 3000
=> 24 000 – 3000 = 21 000</span>

Estimate the answer to 341÷28
Dmitriy789 [7]
To estimate this question, you can round the numbers to be compatible, to make it easier for yourself. The numbers should be able to be divided cleanly, as this is an estimate, not the actual problem solving. You could, for example, round 341 to 300, and 28 to 30, and divide them to get 10.
Hope that helped.

\frac{5}{a + 3} = \frac{3}{a - 2}

5(a - 2) = 3(a + 3)

5a - 10 = 3a + 9

5a - 3a = 9 + 10

2a = 19

a = \frac{19}{2} = 9 \frac{1}{2}

Answer = D.) a = 9 \frac{1}{2}
