Answer:
id say 4 google's calculator is a good math helper as well
Step-by-step explanation:
If you want area it’s 16 if you wanted perimeter it’s 20 if your asking for the number of the width it’s 8
b)
A - wins at both games
c)
A - wins at just one of the games
The value that can turn the fractions into whole numbers is the common denominator......the common denominator of 4,5,2,and 1 is 20.
so we would multiply the entire equation by 20
1/4x - 2/5 = 1/2x + 2....multiply everything by 20
5x - 8 = 10x + 40....poof...bye-bye fractions
Hello from MrBillDoesMath!
Answer:
75
Discussion:
A plane triangle has 180 degrees. Using this in the diagram gives
x + 81 + angle BAC = 180 (***)
(The diagram is a bit fuzzy but I think the above numbers are accurate)
The diagram also shows that (156 + angle BAC )= 180 as a straight line has 180 degrees. So
angle BAC = 180 - 156 = 24
Substituting this in (***) above gives
x + 81 + 24 = 180 =>
x + 105 = 180 => (as 81 + 24 = 105)
x = 180 107 = 75
Check: Does
x + 81 + angle BAC = 180 ?
75 + 81 + 24 = 180. Yes
Thank you,
MrB
