Not sure about the first one but the second one is option c (or -3). You just have to factor and find the solutions (so it would be -7 and 4 and then u just add them)
For question 39 the answer is c
So 45% OF 40 is
45% * 40
0.45 * 40
that is 18
18 is 18% of what number?
18 = 18% * x
18 = 0.18 * x
divide both sides by 0.18
100 = x
45 % of 40, which is 18, and is 18% of 100.
Hope this helps
Hello there! We can answer through division here, given there are 12 donuts in a dozen:
46.2 divided by 12 gives us 3.85 dozens. However, there cannot be a fraction of a dozen in representation of a whole. Rounding to the nearest dozen, we will find that there are about 4 dozens in 46.2 donuts.
For there to be a value of 46.2 donuts, there had to have been more donuts to start with in the dozen. Therefore, we would round up. If there were 3 dozens, that would give us 36 donuts, which would not make sense because there are 46.2 present.
Hope this helps!
