Ming forgot about the decimal in front of the 24 which would be 2400/100, but .24 < 14 because 1400/100 > 24/100
Here is the equation: x+(x+20) = 120
Since you can't combine anything yet, its x+x+20=120
You need to get x by itself
Minus 20 from both sides
Its x+x=100 now
Combine the x's which is now 2x
Now divide 100 by 2 which is 50
x=50
---------------
Lets check:
50+(50+20)=120
Now combine the numbers in the parentheses
Its now 50+70=120
50+70=120 and 70-50=20
As you can see, he ran 50 minutes the first day and 70 minutes the second day
Answer:
10 Kids In Each Van.
Why?
You already know that 5 students will be in 1 car. That leaves 20 students that need to be assigned to vans. Divide 20 by 2 and you get 10!
Answer:
x=44/3
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
substitute what we know
-3 = (-29--3)/(x-6)
simplify
-3 =(-29+3)/(x-6)
multiply each side by (x-6)
-3(x-6) = (-29+3)/(x-6) * (x-6)
the (x-6)'s on the right cancel
-3(x-6) = (-29+3)
distribute
-3x*-3*-6 = -29+3
-3x+18 = -26
subtract 18 from each side
-3x = -44
divide by -3
x = -44/-3
x=44/3
