Step-by-step explanation:
The angle of elevation
It is
away from the point.
If we imagine a right triangle having an angle
.
Hypotenuse
, Opposite=Height from sea level

Hundreds place. three hundred
(x+2)/(x) + (x-3)/(x+2)
Common denominator x(x+2)
Reduce both to common denominator:
x+2)/[x(x+2)] + (x-3)/[x(x+2)] ===> [(x+2)² + (x-3)] / [x(x+2)]
= [x²+4x+4+x-3] / [x(x+2)]
=[x²+54x+1] / [x(x+2)]
Answer:
S = x + 10
R = 2x + 10
Step-by-step explanation:
If R is Roberto's age, and S is his sister's age, then:
R = S + x
R − 10 = 2 (S − 10)
Solve with substitution.
S + x − 10 = 2 (S − 10)
S + x − 10 = 2S − 20
S = x + 10
R = 2x + 10
