If each of the 28 students made at least $25, you would multiply 28 and 25 together to obtain the least amount of money the class raised. That gets, 28x25 = 700. The class made at least $700.
Find how fast it travels in one hour:
460 miles / 2 hours = 230 miles per hour.
A) Multiply the speed per hour by the number of hours:
230 x 8 = 1840 miles in 8 hours.
B) 230 x 20 = 4,600 miles in 20 hours.
C) 460 miles / 2 hours = 230 miles per hour.

Here is how I would show the work for this problem
5- (a-4) = 3 (a+2)
5-a+4 = 3*a+3*2
5-a+4 = 3a+6
-a+9 = 3a+6
-a+9+a = 3a+6+a
9 = 4a+6
9-6 = 4a+6-6
3 = 4a
4a = 3
4a/4 = 3/4
a = 3/4
So the solution is the fraction a = 3/4 (in decimal form 0.75)
