We know: length of a rectangle is 7m less than three times the width.
So let's set the length to l, width to w.
And we can get that l = 3w-7.
We also know that the area of the rectangle is 66 m^2.
Thus, l*w= 66.
So we have:
function 1: l=3w-7
function 2: l*w=66
plug function 1 to 2.
(3w-7)*w=66
3w^2-7w-66=0
w=6 and -11/3.
And the width of a rectangle can not be negative.
So: w=6.
Plug w=6 back to function 1 or 2, either way is correct and can give you the length. In this case, I will plug it back to function 1.
l=3*6-7=11.
So: the width of the rectangle is 6, and the length of the rectangle is 11.
Answer:
the answer is 4
Step-by-step explanation:
32÷8=4 therefore b is 4
You could subtract 4 and if there is not any lemon muffins you would have to do something else
Your answer is k = 5.2
9.3 - 4.1 = 5.2
Hope this helps!
11.25
Convert 15% to decimal of 0.15
Then multiply 0.15 by 75 to get 11.25
