Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.

Step-by-step explanation:
8.5 sheep are white. 34% of 25 is 8.5.
Answer:
Solve for
x
by simplifying both sides of the equation, then isolating the variable.
x
=
−
41
L=R*angle, but the angle *must* be in radians. So, just translate 43 degrees into radians: 43 * pi / 180, and you'll get:
L = 42 * ( 43 * pi / 180 ) ~ 31.504666, which rounded to the nearest hundredth is 31.50 cm.
8 were defective.
Defective percent = 8/84 x 100 = 9.5238% were defective.
Percent not defective = 100% - 9.5238% = 90.4761%
Rounding to the nearest tenth 90.5% were not defective.
The question doesn’t say how to round the answer so you may need to round differently than I did.
