7+3=10
60/10=6
6x7=42
6x3=18
there is 18 trucks in the parking lot
Answer:
180 cars
Step-by-step explanation:
Like you can see in the picture, I like to set up a proportion, so 81 over X and 45 over 100. Then, you can cross multiply, so 81 x 100 = 8100 and then divide, 8100 ÷ 45 = 180, your answer!
Do this.
38 divided by two
then use the equation
38=5+2x
