I think it makes it more easier if you simplify the inequality.
4x + 20 < 40 First subtract 20 on both sides
4x + 20 - 20 < 40 - 20
4x < 20 DIvide 4 on both sides to get the variable "x" by itself
x < 5 [x is less than 5, so x represents the numbers that are less than 5]
[Note:
If the sign is < or >, you use an open circle.
If the sign is ≤ or ≥, you use a closed circle.]
Your answer is the 1st option because the solution is any number that is less than 5
First one is the answer
x = +- sqrt (10)
Step-by-step explanation:
the speed is 130 miles / hour.
that means the train travels 130 miles in 1 hour.
so, the question is, how far is it traveling. when it is going with that speed for 6 hours ?
well, 130 × 6 = 780 miles.
formally, speed is "distance / time".
multiplying this by some time, we have then an expression of "(distance / time) × time", which is then simply "distance".
