5/7 ÷ 1/3 = 5/7 × 3/1 = 15/7
Answer:
x=5, y=3
Step-by-step explanation:
5^3=125
3^3=27
125+27=152
Answer:
Step-by-step explanation:
We have been given an expression 
. We are supposed to combine like terms for our given expression.
We can see that 
are like terms as both of these terms have x variable.
Similarly, 
are like terms as both are constant.
Upon combining like terms, we will get:
Therefore, our required expression would be .
Answer:
<h2><em><u>7</u></em><em><u>.</u></em><em><u> </u></em><em><u><</u></em><em><u>B</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>129</u></em><em><u>°</u></em></h2><h2><em><u>8</u></em><em><u>.</u></em><em><u> </u></em><em><u><</u></em><em><u>N</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>85</u></em><em><u>°</u></em></h2>
Step-by-step explanation:
7. <A + <B = 180° <em>[</em><em>Since</em><em> </em><em>Co-interior</em><em> </em><em>angles</em><em>]</em>
=> 51° + <B = 180°
=> <B = 180° - 51°
=><em><u> <B = 129° (Ans)</u></em>
8. <M + <N = 180° <em> </em><em>[</em><em>Since</em><em> </em><em>Co-interior</em><em> </em><em>angles</em><em>]</em>
=> 95° + <N = 180°
=> <N = 180° - 95°
=> <em><u><N = 85° (Ans)</u></em>
