The parentheses must be placed here 48 - (5 + 2) * 3 + 6 in order for the equation to equal 33.
Let the length of one side of the square be x
x^2 = 7/9
x = sr(7/9) = 0.881917...
The total length of the fence = 4 x 0.881917... = 3.528 miles to 4 s.f.
Answer:
5x+7
Step-by-step explanation:
First of all transfer all the mixed fractions into numbers
![2 \frac{1}{2}](https://tex.z-dn.net/?f=2%20%5Cfrac%7B1%7D%7B2%7D%20)
=2.5=
![\frac{5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B2%7D%20)
so
![\frac{5}{2} x- \frac{6}{4} x- \frac{15}{4} = \frac{3}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B2%7D%20x-%20%5Cfrac%7B6%7D%7B4%7D%20x-%20%5Cfrac%7B15%7D%7B4%7D%20%3D%20%5Cfrac%7B3%7D%7B8%7D%20)
multiply the whole equations by 8
![20x-12x-30=3 \\ 8x-30=3 \\ 8x=33 \\ x= \frac{33}{8}](https://tex.z-dn.net/?f=20x-12x-30%3D3%20%5C%5C%208x-30%3D3%20%5C%5C%208x%3D33%20%5C%5C%20x%3D%20%5Cfrac%7B33%7D%7B8%7D%20)
Answer:
y= 5x +12
Step-by-step explanation:
y=mx+b is slope intercept form
m = slope
b = y intercept
