This is a educated guess, I would say 52% because the red and blue marbles combined is 17 and that's higher than green

Okay so it asks the probability of drawing a red or blue marble so we must add those together.

25 marbles in total

8 + 5 = 13

13/25 is our fraction 

13 ÷ 25 = 0.52

0.52 x 100 = 52 (Always multiply it by 100 to get the percentage.)

52%

So therefore, your answer is 52%

I hope this helped. Have a great day!

A rectangle’s length is 5 inches more than twice its width. its area is 50 square inches. which equation can be used to find its
OLga [1]

The equation of the area of the rectangle is w(2w + 5) = 50. Then the correct option is C.

<h3>What is a rectangle?</h3>

It has four sides and is a polygon. The internal angle adds up to 360 degrees. The opposite sides of a rectangle are parallel and equal, and each angle is 90 degrees. Its diagonals are equally equal, intersecting in the middle.

A rectangle’s length is 5 inches more than twice its width. its area is 50 square inches.

Let the width of the rectangle be w, then the length of the rectangle will be (2w + 5).

Then the area of the rectangle is given as

Area = l × w

Then we have

w(2w + 5) = 50

More about the rectangle link is given below.

Hey there!

Let's think of this with a simpler example. Let's say one package is 4 pounds and one is 2 pounds. How many times heavier is the first than the second?Well, two, because the first package is double the weight of the second package! It's twice as heavy! And to get to that number, we divide four by two!

So, in our actual problem, we just divide 3.92 (bigger package) by 2.8 (smaller package).

3.92÷2.8=1.4

So, the first package is 1.4 times heavier than the first one!

Have a wonderful day!
