Using algebraic expression, we can state that Julie is (x - 5) years old.
<h3>How to Express a Word Problem in Algebraic Expressions?</h3>
Algebraic expressions can be defined as a mathematical expression which helps to simplify a given statement or word problem. Variables, operation sign, and numbers are used.
Given the following:
The age of brad is x years old
We are told that Julie is five (5) years younger than brad. This means that Julie's age is 5 less than the age of Brad. This can be expressed in algebraic expression as:
x - 5
Therefore, we can state that Julie is (x - 5) years old.

Answer:
Infinite Slope, Zero Slope.
Step-by-step explanation:
I do not really get the question... But i think this is your answer.
Let flat rental fee be F
And per mile charge be M
We know that Bob drove 138 miles and was charged $112.96
And Carl drove 209 miles and was charged $142.78.
⇒ F + 138×M = 112.96 .............. (i)
And F + 209×M = 142.78 ................ (ii)
Subtracting (i) from (ii)
71×M = 29.82
⇒ M = 0.42
Substituting value of M in (i)
⇒ F + 138×0.42 = 112.96
⇒ F + 57.96 = 112.96
⇒ F = 55
So the fixed charge was $55 and the per mile charge was $0.42
Answer:
1.) 167.2cm^3 2.) 30.96cm^3
Step-by-step explanation:
V = lwh
= (5.0cm)(4.4cm)(7.6cm)
= 167.2cm^3
V = lwh
= (1.5cm)(2.4cm)(8.6cm)
= 30.96cm^3
Make sure to cube your units on the final answer, and the brackets mean you're multiplying.
6x
