Hi there! :)
Answer:
x = -7.
Step-by-step explanation:
Starting with:
3(2x + 2) = 3x - 15
Begin by distributing '3' with the terms inside of the parenthesis:
3(2x) + 3(2) = 3x - 15
Simplify:
6x + 6 = 3x - 15
Isolate the variable by subtracting '3x' from both sides:
6x - 3x + 6 = 3x - 3x - 15
3x + 6 = -15
Subtract 6 from both sides:
3x + 6 - 6 = -15 - 6
3x = -21
Divide both sides by 3:
3x/3 = -21/3
x = -7.
Answer: Their combined age will be 90.
2x+x=54 will allow you to find their ages. Solve for x ( this is Timothy's age) and you get 18. Times 2 is 36 for Paul's age. Finally, Timothy will be 36 in 18 years and in 18 years Paul will be 54. Add their ages together and you get 90.
The appropriate SI unit for measuring the height of a person is meters.
If im not mistaken its a 1/8 probability
