suppose the number of boy is x ,so the number of girls is 5/4x,so the total number is 9/4x,we knew the number of total students is 36,so 36=9/4x,x is 16.
Answer:
x = 20, <S = 47 degrees, <P = 131 degrees
Step-by-step explanation:
27 + x + 119 + 63 + 3x + 71 = 360
4x + 280 = 360
4x = 80
x = 20
<S = 27 + x = 27 + 20 = 47 degrees
<P = 3x + 71 = 3(20) + 71 = 131 degrees
Answer with Step-by-step explanation:
Let F be a field .Suppose 
and 
We have to prove that a has unique multiplicative inverse.
Suppose a has two inverses b and c
Then, 
where 1 =Multiplicative identity
(cancel a on both sides)
Hence, a has unique multiplicative inverse.
Answer:
<u>For 20 hours it would be $1,500.</u>
Step-by-step explanation:
The equation for this problem would be Y = 50x + 500.
<em>Y is the total charge and x is the number of hours. </em>
