Solve for x.
First multiply everything in the parenthesis by 3.
12 + 12x = 12 + 12x
There is an infinite amount of solutions.
Hope this helps!
A monomial is defined as "one term".
I hope this helps you and have a great day!
Answer:
she flew 1h 30m and ran 30m
Step-by-step explanation:
First we have to make 2 equations, one that represents the distance that it traveled and another that represents the time that it ran
x = time she ran
y =
time she flew
x + y = 2h
x * 12 + y * 76 = 120
we clear x in the first equation
x + y = 2
x = 2 - y
we replace x with (2 - y) in the second equation
x * 12 + y * 76 = 120
(2 - y) * 12 + y * 76 = 120
24 - 12y + 76y = 120
-12y + 76y = 120 - 24
64y = 96
y = 96/64
y = 3/2
this means that 1 hour and a half was flying
x = 2 - y
x = 2 - 3/2
x = 1/2
this means that half hour was runing

If the observed value is 4.5 and the true value is 3, then it is 50%
If the observed value is 3 and the true value is 4.5, then it is -33.3%
