Answer:
1. Total Trip Distance = 190 kilometers
2. To complete the trip, 38 more kilometers left
Step-by-step explanation:
1.
Let total trip be x kilometers.
So we can say
<em>"152 is of total" --- this into equation is:</em>
Total trip is 190 km.
2.
Since already driven 152, to complete 190, you have to drive kilometers more.
So, 38 more kilometers to complete the trip.
Answer: Bea's uncle is 25 years old.
Step-by-step explanation:
Given the equation , we can say that the<u> </u>variable "x" represents the age of Bea's uncle. Then to find his age, we need to solve for "x":
We must add 15 to both sides of the equation:
Now we need to divide both sides of the equation by 3:
Therefore, we can conclude that Bea's uncle is 25 years old.

What we need to find is the surface area of the rectangular prism excluding the area of the hole. First, let's find out the width of the box, we can do this by using the area, the length, and the height, and we can write:
(Formula to find the volume of a rectangular prism)
Now that we have the width, can find the area of the top part of the prism:
The area of the top part of the prism is 20, and the circle has 1/4 of the area of that:
So the area of the circle is 5. Now we just need to find the surface area of the rectangular prism and subtract that result with the area of the circle:
Subtract these two results...:
And we are done!
