Hello, well there are a few ways to write this. Here is one outlook.
Bruce bought three boxes of tiles with the same number of tiles in each.
x = number of tiles
3 = number of boxes
3x = total number of tiles.
Make note, the problem is asking for an expression for how many tiles he used and not the total number of tiles he has. Anyways, the problem then tells us he had to go get 3 more boxes but he used only 2 tiles out of the last box. So he used 2x + 2 tiles We put this together and we have
3x + 2x + 2
5x + 2
Number of tiles Bruce used = 5x + 2
We do the same for Felicia:
She gets 5 boxes, which = 5x. Then she had to go back and just get 5 tiles. So we have:
5x + 5
Number of tiles Felicia used = 5x + 5
First: 10
Second: 10
Third: 10
They are all 10 times smaller than the other one.
Hope this helped. :D
x=5
14x5= 70
70-21=49
this is how I got the answer
Answer:
Not exactly sure but maybe these percentages that i found can help you
Step-by-step explanation:
if there are 12 questions then there are 12 correct answers out of 60 total answers 12 divided by 60 = 0.20 which is 20 percent so upon guessing she has a theoretical 20 percent chance to get all questions correct
Answer:
Area = (5 * 6.5)/2 =16.25 sq.yds
Step-by-step explanation:
The area of a triangle is given by half of the product of the base and the height.
Here
base = 5 yd
height = 6.5 yd
Area = (5 * 6.5)/2 =16.25 sq.yds
