Answer:
x = 133°
Step-by-step explanation:
Straight-line pair - A pair of angles that lie on a straight line.
<em>*</em><u><em>Property</em><em>*</em></u>
The sum of two angles of a straight-line pair is equal to <u>180°</u>.
The given angles – x and y – form a <u>straight-line pair.</u>
==> x + y = 180
<em>{</em><em>y</em><em> </em><em>=</em><em> </em><em>4</em><em>7</em><em>°</em><em> </em><em>(</em><em>given</em><em> </em><em>in</em><em> </em><em>t</em><em>he</em><em> </em><em>question</em><em>)</em><em>}</em>
<em>Substituting</em><em> </em><em>4</em><em>7</em><em> </em><em>for</em><em> </em><em>y</em><em>:</em>
==> x + 47 = 180
<em>Subtracting</em><em> </em><em>4</em><em>7</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
==> x = 47 - 47 = 180 - 47
==><u> x = 133</u>
Answer:
If i did this right, it should be -7
Step-by-step explanation:
5-(-2)=7
-3-(-2)=-1
7/-1=-7
hope this helped :3
Change the mixed fractions to an improper fraction.
4 5/7 = 32/7
1 6/7 = 13/7
Now you can easily subtract since both fractions have common denominators
32/7 - 13/7
(Think: 32 - 13 = 19)
Change the improper fraction to a mixed fraction
19/7 = 2 5/7
Answer: 2 5/7
Hope I helped =)
