Step-by-step explanation:
your welcome
So the time to time rule is 4 so add 4 to all numbers = 320 360 400 440 and 480
The answer is A. You can get that in by plugging in and checking or by substitution. In order to use substitution here, you would plug in 3x + 3 into y in the first equation. You would then distribute the 2 and solve for x, which would give you 0. Then you could plug that into either equation to find that y = 3.
Let the number be x:
3*x-2=13
∴3x=13+2
∴3x=15 (divide both sides by 3)
∴x=5 the answer is C
Answer: the number is -14
Step-by-step explanation: let the number be x
2(x+4) = x-6
2x+8 = x-6
2x-x = -6-8
x = -14
