Answer:what are all the choices
Also it’s 0
Step-by-step explanation:
Answer:
First we add 7 on both sides
-7x+3y= -6.3
+7. +7
___________
then we simply
-7x + 7x= -1
bring down the 3y
-6.3+ 7x = 0.23
So, -1x+3y=0.7
2y = 0.7
___ __
2. 2
y = 0.35 or 35!!
Step-by-step explanation:
Hope this helps
Shorter side: 130ft
longer side: 260ft
greatest possible area: 33800ft^2
basically get the equations for area and perimeter which will be
A: lw (length x width)
P: l + 2w
Substitute them into eachother and you get the equation:
-2w^2+520w = A
find the vertex of this parabola which will give you the greatest width which is 130m
Then u can find length and area from this width
How to solve:
![\frac{5}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B6%7D%20)
-
![\frac{3}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B8%7D%20)
Write all numerators above the least common denominator which is 24 in this case.
![\frac{20-9}{24}](https://tex.z-dn.net/?f=%20%5Cfrac%7B20-9%7D%7B24%7D%20)
Subtract the numbers
![\frac{11}{24}](https://tex.z-dn.net/?f=%20%5Cfrac%7B11%7D%7B24%7D%20)
Alternate form: 0.458333
The final, simplified, fraction answer is:
