588 because big#-little#÷the original number×100, so 5.6-4.2/4.2x100=588.
Answer:
1. m<UTV=m<STR Vertical angles
2. m<R+ m<S+m<T. Triangles must add up to 180°
3. 3x+2x+85°=180°. Substitution
4. X=19. Algebra
Answer:
200
Step-by-step explanation:
C = 0.007x² − 2.8x + 100
There are two ways we can find the minimum. The first is by noticing that this is an upwards parabola, so the minimum is at the vertex. For y = ax² + bx + c, the vertex is at x = -b/(2a).
x = -(-2.8) / (2 × 0.007)
x = 200
Alternatively, we can minimize C using calculus. Take the derivative with respect to x and set to 0:
dC/dt = 0.014x − 2.8
0 = 0.014x − 2.8
x = 200
My Work/Reasoning:
First we find the sum of 1/3 and 1/5.
Then, we find the multiplicative inverse, I guess it's also known as the reciprocal.

Finally, we simplify.
