let's practice:
Hank is on a field trip. He has to travel 56 miles to get to his destination. He has traveled 18 miles so far. How much further does he have to travel?
6
Multiple Choice
what is the unknown information (x) in this problem?
The name of the destination
the total distance to travel
how many more miles does he need to travel
the amount of miles he has traveled so far
7
what is relevant in the problem?
the total distance
the distance travel so far
IDENTIFY THE OPERATIONS WE WILL NEED TO USE

WE CAN HAVE MORE THAN ONE EQUATION REPRESENTING THE SITUATION
9
Multiple Choice
WHAT EQUATION DOES NOT REPRESENT THE SITUATION?
56-18=X
X+18=56
18+56=X
10
Multiple Choice
WHAT IS THE EQUATION REPRESENTING THIS SITUATION:
The 2 smallest in the world are Vatican City and Monaco. Vatican city is1.37 squared kilometers smaller than Monaco,, which is 1.81 squared kilometers in area. What is the area of Vatican city?
2=1.37 + 1.81
1.81 - 1.37 = v
1.81 + 1.37 = v
11
Multiple Choice
WRITE THE EQUATION FOR THIS PROBLEM:
There are 45 students on the football team. This is 13 more than the number of students on the basketball team. How many students are on the basketball team?
45 = 13 + x
45 + 13 =x
43 + 13 = 56

Multiple Choice
A used mountain bike costs $79.95. This is $120 less than the cost of a new one. If c is the cost of the new bike, which equation can you use to find the cost of a new bike?
120 - 79.95 = c
79.95 = c -120
