Answer:
2 3/4
Step-by-step explanation:
6 19/20 - 4 1/5 = ?
6 19/20 - 4 4/20 = ?
2 15/20 = ?
Simplified = 2 3/4
Do a proportion
40/100= 8/x
8 x 100= 800
Cross multiply and divide
800 divided by 40= 20
So answer is 20
Answer:
It is a mixed number because a fraction would be like 4/9.
Step-by-step explanation:
How you remember is that a decimal is in a place that makes it a mixed number,
Answer:
w= 6
Step-by-step explanation:
I just started by making an educated guess using the values already given. Then I inserted that into the problem to see if it worked.
L= 2w - 5
I used 6 as a random, educated guess for the value of w.
L = 2(6) - 5
L = 12-5
L = 7
Then, multiply L by 2 to account for both side lengths of the rectangle.
7(2)= 14
Subtract that value from the total perimeter to find what the width must equal.
26 - 14 = 12
Divide that answer by 2 since there are two sides for width.
12/2 = 6
I know this was kind of long, but I hope it helps! :)
