Step-by-step explanation:
line graphs, Circle graphs, scatter plot are the graph that are best for displaying numerical data
That one looks very difficuly
Answer:
Step-by-step explanation:
Given that every day at noon, a bus leaves for Townville and travels at a speed of x kilometers per hour. Today, the bus left 30 minutes late.
If the driver drives 7/6 times as fast as usual, she will arrive in Townville at the regular time.
If correct time leaves then distance = time *speed
280 = t*x where t is the time in hours
Or t = 280/x
Now speed changes to 7x/6 while time changes to (t-1/2)
So 280 = (t-1/2) 7x/6
![280 = (\frac{280}{x} -\frac{1}{2} )(\frac{7x}{6} )\\240= (\frac{280}{x} -\frac{1}{2} )x\\\\x=80](https://tex.z-dn.net/?f=280%20%3D%20%28%5Cfrac%7B280%7D%7Bx%7D%20-%5Cfrac%7B1%7D%7B2%7D%20%29%28%5Cfrac%7B7x%7D%7B6%7D%20%29%5C%5C240%3D%20%20%28%5Cfrac%7B280%7D%7Bx%7D%20-%5Cfrac%7B1%7D%7B2%7D%20%29x%5C%5C%5C%5Cx%3D80)
x = 80 km per hour
Answer:7 x+3
Step-by-step explanation: 3+4=7
Answer:
x = -7.22 or -7 2/9
Step-by-step explanation:
-73 = 4(3x - 2) - 3x
-73 = 12x -8 -3x
-73 = 9x - 8
-65 = 9x
-65/9 = x
-7.22 or -7 2/9 = x
