Answer:
11 years
Step-by-step explanation:
in 11 years
Sam would be 13
and his mother would be 39
39/13 = 3
Look for the word "Is" first - this is where your "=" goes. (In your problem, it actually says "is equal to".)
So now you know you have = 9.
The next key word on the left is "quotient" - that means divide. It says "quotient of a number and 5" - so we'll divide an unknown number (y in your problem) by 5.
Three less than means subtract 3 from that quotient.
So you need to start with the quotient: y/5 - 3 = 9.
hope it helps!
Take the 17.85 and divide by 110 than multiply ur answer by 10.

Step-by-step explanation:
<u>Step 1: Define</u>
R(x) = 6x - 3
S(x) = -3x - 8
<u>Step 2: Find</u>
- Substitute in functions: R(x) - S(x) = 6x - 3 - (-3x - 8)
- [Distributive Property] Distribute negative: R(x) - S(x) = 6x - 3 + 3x + 8
- [Addition] Combine like terms: R(x) - S(x) = 9x + 5
