Answer:
4/5 is grater than 45/100
Step-by-step explanation:
Why?
because in percentage you make the bottom # a 100 one of them already has that and when it has 100 on the bottom it tells you that the top # is the percentage so 45/100 is 45%
now to make 4/5 a percentage what times 5 = 100?
20 does
so you times the top and bottom by 20
4*20= 80
now your fraction is 80/100 (top # tells you the %)
it's 80%
80% is grater than 45%
The answer is -1.6 because 5 x -1.6 is -8 and -8 + 8 is 0
L= length= 2w+4
w= width
P= perimeter= 7w-3
SOLVE FOR WIDTH
Perimeter of a Rectangle Formula
P= 2(l + w)
7w - 3= 2((2w + 4) + w)
combine like terms in parentheses
7w - 3= 2(3w + 4)
multiply 2 by parentheses
7w - 3= (2*3w) + (2*4)
multiply in parentheses
7w - 3= 6w + 8
add 3 to both sides
7w= 6w + 11
subtract 6w from both sides
w= 11 width
LENGTH
l= 2w + 4= 2(11) + 4= 22 + 4= 26
PERIMETER
P= 7w-3= 7(11) - 3= 77 - 3= 74
CHECK
74= 2(26 + 11)
74= 2(37)
74= 74
ANSWER: The length is 26, the width is 11 and the perimeter is 74.
Hope this helps! :)
