Answer:
answer given in step by step...
Step-by-step explanation:
13x+13(x+1)+13(x+2)=312
13x+13x+13+13x+26=312
39x+39=312
39x=312-39
39x=273
x=7
first number=13x=13*7=91
second number=13(8)=104
third number=13(9)=117
Answer: x = 3
Step-by-step explanation:
First you need to start by adding positive 4x to both sides since the 4x is a negative. 4x + (-7x) = -3x. Then it is just simply -3x+2 = -7. Since 2 is a positive number subtract both both sides by 2. Then you should get -3x = -9. Then divide both sides by -3 and the answer is x = 3.

Answer:
36, 29, 22, 15, 8
Step-by-step explanation:
Step 1: State known information
First difference is -7
Third term of the sequence is 22
Step 2: Find first 5 terms
You just need to add and subtract 7 to 22 and the answer 5 times
1. 36 +7
2. 29 +7
3. 22 <- We know 22 is the 3rd term
4. 15 -7
5. 8 -7
Therefore the first 5 terms of the sequence is 36, 29, 22, 15, 8
That would be correct because if x times x =16 than that means that the square root of 16 is 4
