Answer:
z=-(51p+84)/(d+p)
Step-by-step explanation:
-p*(51+z)=dz+84
-51p-pz=dz+84
-51p-84=dz+pz
z=-(51p+84)/(d+p)
Answer:
The value of x would be
or ![\frac{3}{8}z](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B8%7Dz)
Step-by-step explanation:
Given,
x tons of 10% gravel G mixture is mixed with y ton of 2% gravel G to obtain 5% gravel mixture,
Thus, gravel G in x ton + gravel in y ton = gravel G in the resultant mixture,
⇒ 0.1x + 0.02y = 0.05(x+y),
0.1x - 0.05x = 0.05y - 0.02y
0.05x = 0.03y
![\implies x = \frac{0.03}{0.05}y=\frac{3}{5}y----(1)](https://tex.z-dn.net/?f=%5Cimplies%20x%20%3D%20%5Cfrac%7B0.03%7D%7B0.05%7Dy%3D%5Cfrac%7B3%7D%7B5%7Dy----%281%29)
Now, resultant mixture is z ton,
i.e. ![z=x+y](https://tex.z-dn.net/?f=z%3Dx%2By)
![\implies y = z - x](https://tex.z-dn.net/?f=%5Cimplies%20y%20%3D%20z%20-%20x)
From equation (1),
![x=\frac{3}{5}(z-x) = \frac{3}{5}z-\frac{3}{5}x](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3%7D%7B5%7D%28z-x%29%20%3D%20%5Cfrac%7B3%7D%7B5%7Dz-%5Cfrac%7B3%7D%7B5%7Dx)
![x+\frac{3}{5}x=\frac{3}{5}z](https://tex.z-dn.net/?f=x%2B%5Cfrac%7B3%7D%7B5%7Dx%3D%5Cfrac%7B3%7D%7B5%7Dz)
![\frac{8}{5}x=\frac{3}{5}z](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B5%7Dx%3D%5Cfrac%7B3%7D%7B5%7Dz)
![x=\frac{3}{8}z](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3%7D%7B8%7Dz)
Y + 2 > - 3x - 3
y > -3x - 3 - 2
y > -3x - 5
ur line will be dashed (because there is no equal sign in ur problem)...so that eliminates A and C
ur y int (where the line crosses the y axis) is at (0,-5)...the x int (where the line crosses the x axis) is at (5/3,0)...ur slope is -3
shading will occur above the line
ur graph is : graph D
Max Area:
225 cm^3
Min Area:
80.36 cm^3
i got this from socratic.. hope it helps ;)
Since the sign before the parentheses is a + , we can just remove the parentheses.
<span>5i + (-9 - i) = 5i - 9 - i = -<u>9 + 4i</u></span>
