You and a classmate have a bug collection for science class. you find 5 out of every 9 bugs in the collection. you find 4 more bugs than your classmate. how many bugs are in the collection?

36

Step-by-step explanation:

In this collection, we learn that the ratio of bugs you found to bugs your classmate found is 5:4. A ratio is a mathematical expression that indicates the number of times that one value contains another one. Moreover, we also learn that you found 4 more bugs than your classmate. If we are to maintain the same ratio, we need to multiply both numbers by the same factor. The only option that fulfills these characteristics is 20:16. This means that there are 36 bugs in the collection.

answer is 144

step-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
