Answer:
Elgas is 35.
Step-by-step explanation:
Let's set up an equation.
Alvin is 7 years younger than Elgas.
A = E - 7
The sum of their ages is 63.
A + E = 63
Let's use substitution.
Plug in the first equation of A into the second equation.
A + E = 63
(E - 7) + E = 63
Combine like terms.
2E - 7 = 63
Add 7 to both sides.
2E = 70
Divide both sides by 2.
E = 35
Elgas is 35.
Hope this helps!

Answer:
The complete answer is explained below.
Step-by-step explanation:
The problem is demanding to simply determine the number of years each color light would last.
We know the following information from the question:
- As it is clear that a red light remains TURNED ON 50% of the time.
- Green remains TURNED ON 42% of the time
- Yellow remains TURNED ON 8% of the time.
Also the bulbs for each color are LED and are designed to last 100,000 hours. So, each light does last 100,000 hours.

Answer:
4.1 calls
Step-by-step explanation:
The number of calls (c) that Roger expects to get as a function of how many inches of snow fall (s), is described by the following linear model:

Therefore, when s = 4.7 inches, the number of service calls that Roger expects is:

Rounding to the nearest tenth, Roger will get about 4.1 calls.
