Whenever you have a variable (in this case, t), and you don't know the value of it, your answer will have the variable in it.
So, if I had -10t's, and 3t's, that leaves me with -7t's.
So, the answer would be -7t+50 (you can't reduce it any further than that, because you don't know what t is)
So, if you have two variables, such as 3a + 2a, the answer would be 5a.
If it was 3a + 2a +50, it would just be 5a + 50, because you don't know what "a", is, therefore you can't multiply it.
I hope that made sense.
What you want to do here is get the t by itself on one side of the equals sign so it will look like t=something. Here is how you'd solve this equation. 3t+15=65 (subtract 15 from both sides) 3t=50 (divide both sides by 3) and you get t=16.666666667 If you put a horizontal line over the six its usually considered correct or just convert it to a fraction. t=50/3
-50 plus 50 equals 0
sixty is equal to 10 plus 50, and as 10 equals 50, and 50 equals 79, then it would be fair to assume that 60 equals 50 plus 79, which is 129.
The answer is 983.
2,500 Or; 50+50=100
4849494949505050------394
100 + 50 + 100000000 = 100000150
It is: 90+50 = 140
50 + 92 = 142.
80 + 50 = 130
50 + 5 + 2
