The truck can cover 145 miles in 2.5 hours, so the speed of the truck is
145÷2.5=58 miles per hour
the car's speed is 1.5 times faster: 58×1.5=87 miles per hour
suppose in x hours they will meet:
distance covered by truck in x hour: 58x
distance covered by car in x hour: 87x
total distance: 145 miles
58x+87x=145
x=1
Answer:
Step-by-step explanation:
If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value of X.
Answer: 133. Im not sure that is correct because that's impossible, but I added 132 to 400 to get 532, then dived by 4. Worked it backwards to get 133.
-2, 1.5 Hopefully it helps!!!
Answer:
x = -0.5
Step-by-step explanation:
5x - 5 = 9x + 3
add 5 on both sides to cancel out 5
5x = 9x + 8
take away 9x on both sides to cancel out 9x
-4x = 8
divide by -4 to get x
x = -0.5
