You miles in a car is 32miles
There are always two possible unit rates.
Either way, you just divide to find it.
(5 hours) / (216 miles) = 0.023 hours per mile .
(216 miles) / (5 hours) = 43.2 miles per hour .

Answer:</h3>
8m and 12a
<h3>
Step-by-step explanation:</h3>
Like terms are terms that can be combined to condense a mathematical expression or equation.
Unlike Terms
Unlike terms are defined as terms that have different variables or powers.
- This means that for terms to be unlike they must either be multiplied by a different variable, like x and y, or have different exponents.
If terms meet either of these requirements, they are unlike. On the other hand, for terms to be like they must have both the same variable and power. The coefficients for the terms are not important.
Final Answer
All of the answer choices are to the first power, so the exponents are not important for this question. However, the last 3 answer choices all share the same variable. This means that they are all like terms.
The first answer choice, 8m and 12a, have different variables. This means that they cannot be combined and are unlike terms.
Let x=the first number
Then x+7=second number
And 4(x+7)+2=third number (2 more than 4 times the second)
Now we are told that:
x+(x+7)+(4(x+7)+2)=85 get rid of parentheses
x+x+7+4x+28+2=85 simplify
6x+37=85 subtract 37 from each side
6x+37-37=85-37
6x=48
x=8---first number
x+7=8+7=15 second number
4(x+7)+2=4*15+2=62 third number
CK
8+15+62=85
85=85
