55+(x+25)=180
55+x+25=180
25+55+x=180
80+x=180
x=180-80
x=100
Answer:
25/4
Step-by-step explanation:
Multiplying numerators gives 4950 and multiplying denominators gives 792. 4950/792. simplify to get simplest form as 25/4
Answer:
4 hours
Step-by-step explanation:
3 x 12 = 36
36/9 = 4
<span>c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.</span>
I feel like it would be rational because 0/12 = 0, and 0 is a rational number.
