Hattie jumps rope 57 times in 3 minutes. If Hattie jumps at a constant speed, how many times does she jump per minute?

11/4 is 2 3/4 12/3 is 4 2 3/4 times 4 is 11 so they used 11 times more mustard than ketchup 11 times 2 3/4 is 30 1/4

When x is 4, y is 12. That is because the constant is 48. y=c/x. I think x is 4/3 when y is 64, given c is 48.

500 minutes.If this is homework, be sure to show your work.

the distance is 178.3 miles and it will take you 3 hours and 20 minutes to reach.

Let's rewrite as

7(3x+5) = 8x -1(1-4x)
Let's distribute
21x + 35 = 8x -1 + 4x
collect like terms
21x + 35 = 12x -1
Put all the x's on one side by subtracting 12x from both sides
21x -12x + 35 = 12x -1 -12x
simplify
9x + 35 = -1
get all the constants on the right side
9x + 35 - 35 = -1 - 35
9x = -36
divide both sides by 9 to get x by itself
9x /9 = -36/9
x = -4

check in original equation

7(3(-4)+5) = 8(-4) -(1-4(-4))
7(-12+5) = -32 - (1+16)
7 (-7) = -32 - (17)
-49 = -32-17
-49 = -49

8.86364 miles per hour. :)

speed= distance/time
speed=4281/4.5 km/h
speed=951.34 kmph
hence, the plane fly at 951.34 kmph
