Answer:
(4x -14)/3
Step-by-step explanation:
Assuming you intend mixed number coefficients, only the coefficients of x can be combined.
(-2 1/4)x +(3 7/12)x -(4 2/3) = x(-2 1/4 +3 7/12) -(4 2/3)
The mixed numbers are added in the usual way.
(-2 1/4) +(3 7/12) = (-2 +3) +(-1/4 +7/12) = 1 +(-3/12 +7/12) = 1 4/12 = 1 1/3
So the expression simplifies to ...
(1 1/3)x -(4 2/3)
This might be better written as ...
(4x -14)/3

<em>Comment on mixed numbers</em>
It is hard to write mixed numbers so they can be properly interpreted in an algebraic expression. In general, they are better written as improper fractions or as decimal numbers (if the decimal terminates).
Yea I’m not sure more info?
Answer:
C. 5/13
Step-by-step explanation:
Remember SOHCAHTOA
Sine is opposite over hypotenuse. The side opposite the 23° angle is 5, and the hypotenuse is 13.
So, sin 23° = 5/13
Answer:
The percent of 11 to 50 is 22%
The percent of 72 to 80 is 90%
Step-by-step explanation:
Find an equivalent fraction with denominator 100
Then multiply:
72 × 100
Divided by the original number which was 80
Then multiply that by 1/100 which equals 90/100
So 90%
Answer:
{(1,0), (2,0), (3,0)}
Step-by-step explanation:
x-values can have the same Y-values from another pair, but no Y-value can have the same x-value of another pair
