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).
Answer:
52 yd
Step-by-step explanation:
The formula for arc length is s = rФ, where r is the radius and Ф is the central angle in radians.
Here the central angle is 300° and the radius is 10 yd.
Convert 300° to radians:
π rad
Multiply 300° by the conversion factor ------------
180°
obtaining
(300/180)π = 5.2 rad
Then the arc length is s = rФ = (10 yd)(5.2 rad) = 52 yd
