Actual anwser is 910.5
Step-by-step explanation:
Answer:
50.5
Step-by-step explanation:
2xy+2x^2 And we know x=-2.5 and y=-7.5.
In order of operations, exponents come first.
x^2 = -2.5 * -2.5 = 6.5.
6.5*2=13.
2xy + 13
2x=-5
-5*-7.5 = 37.5
37.5 + 13
50.5
if C = 100 degrees, then its Fahrenheit equivalent would be 482 degrees.
F = C x 9/5 + 32
C = 100
F = 100 x 9/5 + 32
F = (100 * 9)/5 + 32
F = 900/5 + 32
F = 450 + 32
F = 482
Your anwer is option B. x=1/2
5.20 divided by 2 is 2.6
then to check all you do is 2.6*2 and you get 5.20
Hope this helped!!! :D
