If you're looking for x then it's 7. The value of -4 is -4.
D = vt
Distance traveled by train
d = 55t
Distance traveled by plane
d = 285t
Total distance
d = 1020
So, you do:
distance traveled by plane + distance traveled by train = total distance
(55t) + (285t) = 1020
Solve for t
t = 3 hours
t is the time traveled by each so 3 hrs traveled by train and 3 hrs traveled by plane
Total time = 3 + 3 = 6 hours
Answer:
x ≥ −42
Step-by-step explanation:
Let's solve your inequality step-by-step.
x/7≥−6
Step 1: Simplify both sides of the inequality.

Step 2: Multiply both sides by 7.
x ≥ −42
(x) + (x + 2) = 58
2x + 2 = 58
2x = 56
x = 28
The two numbers are 28 and 30.
Hope this helps!
X would be -37. since youll subtract the 19 from both sides to get x=-37
