Number lines are helpful because they’re a visual used to solve problems. Usually use them for greater and less than. When you show something is greater than or less than you use a a circle. And when you show something is greater than or equal to or less than or equal to you use a solid circle. They can go into negatives or just stay positive.

Answer:

3/2 or 1 1/2

Step-by-step explanation:

5÷3 1/3

5/1 ÷ 10/3 because you have to get it into an improper fraction form in order to divide

5/1 × 3/10 because you have to multiply the first number by the reciprocal

5 and 10 cancel out so you would have 2 at the bottom

An angle measures 47.2° less than the measure of its supplementary angle. What is the measure of each angle? on ixl

SVEN [57.7K]

Answer:

The measure of one angle is $113.6^o$ , and the measure of the other one is $66.4^o$

Step-by-step explanation:

Recall that supplementary angles are those whose addition renders $180^o$

We need to find the measure of two such angles whose difference is precisely $47.2^o$ .

Let's call such angles x and y, and consider that angle x is larger than angle y, so we can setup the following system of equations:

$x+y=180^o\\x-y=47.2^o$

We can now solve this by simply combining term by term both equations, thus cancelling the term in "y", and solving first for "x":

$x+y=180^o\\x-y=47.2^o\\\\2x=180^o+47.2^o\\2x=227.2^o\\x=113.6^o$

So, now we have the answer for one of the angles (x), and can use either equation from the system to find the measure of angle "y":

$y=180^o-x\\y=180^o-113.6^o\\y=66.4^o$
