Step-by-step explanation:
4. 4(x+1) = 12
4x+4 =12
4x = 12/4
4x = 3
x = 3/4
Your answer should be 16. If you have any questions on any of the steps, don't hesitate to send me a message!
I can try and help, 36 = 3 (4.5 + x), whichif you distribue, you get 36 = 13.5 + 3x, and if you solve from there, you get 22.5 = 3x, then your answer, 7.5 = x
Non-proportional because all the dots are scattered I believe a proportional chart will have a straight line please correct me if I’m wrong :)
Answer:
10! because 3 to get 15 is 5 and 2×5 is 10
