Let t be the number of tolls they crossed.
Amount they spent at each toll = $1.75.
Amount they spent at gas station = $28.
Let C be the total amount they spent on gas and tolls.
If they crossed 1 toll, then
C = 28 + 1.75(1).
If they crossed 3 tolls, then,
C = 28 + 1.75(3)
If they crossed t tolls, then,
C = 28 + 1.75t
Here, the terms are 28 and 1.75t and the factors are 1.75 and t.
To find the number of black bicycles in a total of 25 bicycles given a ratio, divide the total number of bicycles by the total number of parts in the ratio and multiply by the number of parts representing black bicycles.
To find the number of black bicycles, we first need to find the total number of parts in the ratio. The ratio of gray bicycles to black bicycles is 6 to 9, which means the total number of parts is 6 + 9 = 15. We can then calculate the number of black bicycles by dividing the total number of bicycles by the total number of parts and multiplying by 9. So, the number of black bicycles is (25/15) x 9 = 15 bicycles.

Answer:
7/10
Step-by-step explanation:
4 1/2=9/2

9/2-19/5=45/10-38/10=7/10
rest are amphibians. How many more types of reptiles are there than amphibians in the exhibits?
Answer:
There are 35 more types of reptiles than amphibians
Step-by-step explanation:
112-72=40
75-40=35
The 40 is the number of amphibians and if you do the number of reptiles minus the number of amphibians (75-40) you get how many more reptiles there are than amphibians.
The zoo has 32 more types of reptiles than amphibians. This was determined by subtracting the number of amphibians from the number of reptiles.
The subject of this question is mathematics, specifically a problem requiring the subtraction operation to determine the difference between two numbers. When you are told there are 112 types of reptiles and amphibians at the zoo and 72 of them are reptiles, you are being asked to find out how many are amphibians. To do this, you simply subtract the number of reptiles from the total number of amphibians and reptiles, which is 112 - 72 = 40. Now, the student asked how many more types of reptiles there are. Since there are 72 reptiles and 40 amphibians, you would find the difference by subtracting 40 from 72, giving the result of 32. So, there are 32 more types of reptiles than amphibians at the zoo.
