Let’s make an equation
Let’s say x = amount of years after
Smith = 8, mother = 42
3(8 + x) = 42 + x
24 + 3x = 42 + x
2x = 18, x = 9
Solution: after 9 years
Answer:
8
Step-by-step explanation:
total number of pencils = 186
number of students = 23
number of pencils each student gets = number of pencils ÷ number of pencils
=186/23
=8.08
so each student gets 8 pencils
8,748 is the answer because multiple all the number and get 8,748
I'm going to assume you've learn sin, cos, and tan. To find a you must do:

Once you find a, you can use the Pythagorean Theorem to find b:

Or you can do:

You can find these functions on a scientific calculator. Let me now if you need more help.
2(3x - 1) ≥ 4x - 6 | Starting equation
6x - 2 ≥ 4x - 6 | Distribute the 2
2x - 2 ≥ -6 | Subtract 4x from each side
2x ≥ -4 | Add -2 to each side
x ≥ -2 | Divide both sides by 2
So, x must be greater or equal to -2 to be in the solution set.
