<h2>Linear system</h2>It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
<h3>Ratio and proportion</h3>A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Given
Add four years to my present age, the result will be two times my camper’s.
Five years ago my age was 3/4 of what hers will be in eight years.
<h3>To find </h3>The present age of counselor.
<h3>How to find the present age of counselors?</h3>Add four years to my present age, the result will be two times my camper’s. then,
y +4 = 2x .....1
Five years ago my age was 3/4 of what hers will be in eight years.
.....2
From equation 1 and 2
Put the value of x in equation 2, then
y + 4 = 2x
y + 4 = 2 *12
y = 24 - 4
y = 20
Thus the counselor's age is 20 years.

Answer:
1. Top: 18 (cm²)
2. Left: 12 (cm²)
3. Front: 24 (cm²)
4. Bottom: 18 (cm²)
5. Back: 24 (cm²)
6. Right: 12 (cm²)
Surface area: 108 (cm²)
Step-by-step explanation:
You can find the surface area of this rectangular prism by using the grid.
We know that in order to find the area of a rectangle, we must multiply the length by the height. Let me make this clearer.
In the grid, the top has a length of 3 centimeters and a height of 6 centimeters. To find the area, we multiply these side lengths.
Now, we know that the area of the top is 18 centimeters.
Simply find the area of each side, then combine the areas at the end to find the <u>SURFACE</u> area.
