D would be the correct answer. Since angle W and angle Z form a straight line, they are supplementary angles. Supplementary angle add up to make 180°, which is what D states.

A doesn't make sense.

If B was true, then the angles would be complementary (adding up to 90°). They form a straight line, though, so it's incorrect.

C is wrong for reasons aforementioned.

The number of measles cases increased 13.6 % to 57 cases this year, what was the number of cases prior to the increase? (Express

ELEN [110]

Answer:

The number of cases prior to the increase is 50.

Step-by-step explanation:

It is given that the number of measles cases increased by 13.6% and the number of cases after increase is 57.

We need to find the number of cases prior to the increase.

Let x be the number of cases prior to the increase.

x + 13.6% of x = 57

$x+x\times \frac{13.6}{100}=57$

$x+0.136x=57$

$1.136x=57$

Divide both the sides by 1.136.

$\frac{1.136x}{1.136}=\frac{57}{1.136}$

$x=50.176$

$x\approx 50$

Therefore the number of cases prior to the increase is 50.
