Equation: 53x + 460 = 1096
Solution 1096 - 460 = 53x
636/53=x
12=x
12 hours
Answer:
speed of the boat = 100 mph
Step-by-step explanation:
Let x = speed of the boat
upstream speed = x - 4
downstream speed = x + 4
time = 24/(x - 4) = 26/(x + 4)
Cross multiply:
24(x + 4) = 26(x - 4)
24x + 96 = 26x - 104
104 + 96 = 26x - 24x
200 = 2x
x = 100 mph
The greatest whole number that rounds to 2,500 is 2,549. The least whole number that rounds to 2,500 is 2,450.
Switch the x and the y and solve for y
eg inverse of 2y= 3x+1
swith x and y
2x=3y+1
now solve for y
y =(2x-1)/3
