Answer: 
r=26
Step-by-step explanation:
Given: Mrs. Morton rewards her students on behave well by putting 3 marbles into a marble jar.
If the jar contains 24 marbles. and r represent the number of additional times the class is rewarded then the required equation will be
If we solve it, we will get the minimum the jar contains 24 marbles.
To solve equation, subtract 24 from both sides, we get
Hence, the minimum whole number of additional times they need to be rewarded so they can have a party=26

Your problem is an example of a distance problem, so you muct know the formula to find the distance. To find the distance we simply multiply the rate by the time, or as you'll see more often, d = r t. That means to calculate distance traveled you need rate and time.
Take note, planes are traveling in opposite direction, which means 2000 miles will be the sum of the distances that the two planes have traveled.
D (Plane 1) + D(Plane 2). = 2000
Let t = time in minutes
560t + 500t = 2000
Solve for t. Take it ftom here.
Answer:
B) 14 - 2i
Step-by-step explanation:
m + n = 10 + i + 4 -3i = 14 -2i
