Answer:
Truck D.
Step-by-step explanation:
Below are the rates of travel of 4 shipping trucks.
Truck A: 300 miles in 4 hours Truck B: 240 miles in 3 hours Truck C: 325 miles in 5 hours Truck D: 170 miles in 2 hours.
Speed = distance/time
Speed of Truck A,
Speed of Truck B,
Speed of Truck C,
Speed of Truck D,
It can be seen that the speed of Truck D is more out of Trucks A,B and C. Hence, Truck D is moving at a faster rate.
For perpendicular lines, m1m2 = -1 or m2 = -1/m1; where m1 and m2 are the slopes of the lines.
Here line 1 is 2x - y - 7 = 0
y = 2x - 7; Hence m1 = 2
m2 = -1/2
Required equation y - y1 = m2(x - x1)
y - (-1) = -1/2(x - 4)
y + 1 = -1/2x + 2
y = -1/2x + 2 - 1
y = -1/2x + 1
<span>In finding the solution for x, the idea is to isolate the variable on one side of the equation
5 - 3x = 2x + 9 |3x is added to the equation first
5 = 5x + 9 | 9 is subtracted from EQ second
-4 = 5x </span>
Answer:
10
Step-by-step explanation:
Cross multiply
2/3=x/15
3x=30
Divide by 3 on both sides
x=10
So, 2/3= 10/15
Hope this helps! :)
