24x−6y=18 Step 1: Add 6y to both sides. 24x−6y+6y=18+6y24x=6y+18
Step 2: Divide both sides by 24.24x24=6y+1824x=14y+34
Answer: x=14y+34

Answer:
Step-by-step explanation:
so from the silly drawing, you can see that the triangle is 4 feet off the ground, and that we want to find the Opp side from our angle of 15 °
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
use TOA to find the Opp side of the triangle .. which is labeled X
Tan(15) = X / 15
15* Tan(15) = X
4.019 = X
so the bird is up 4 feet in the tree.. not very high up, plus the 4 feet that the apple is already off the ground, soo
the tree... to where the bird is, at least, is 8.019 feet..
did this make sense? :/
hope the drawing helped :P
Answer:
The value of "a" in the given system of equations is 16
Therefore a=16
Therefore substitute a=16 then equation (2) becomes
12x-8y=2(16)
12x-8y=32
Step-by-step explanation:
Given system of equations are ![3x-2y=8\hfill (1)](https://tex.z-dn.net/?f=3x-2y%3D8%5Chfill%20%281%29)
and
have infinite number of solutions
To find the value of a in the given system of equations :
From given the equations have infinite number of solutions and so they refers the same line
Therefore the equation (2) becomes
![4(3x-2y)=2a](https://tex.z-dn.net/?f=4%283x-2y%29%3D2a)
( by
)
![32=2a](https://tex.z-dn.net/?f=32%3D2a)
![\frac{32}{32}=\frac{2a}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B32%7D%7B32%7D%3D%5Cfrac%7B2a%7D%7B32%7D)
![1=\frac{a}{16}](https://tex.z-dn.net/?f=1%3D%5Cfrac%7Ba%7D%7B16%7D)
![1\times 16=\frac{a}{16}\times 16](https://tex.z-dn.net/?f=1%5Ctimes%2016%3D%5Cfrac%7Ba%7D%7B16%7D%5Ctimes%2016)
![16=a](https://tex.z-dn.net/?f=16%3Da)
Rewritting the above equation we get
![a=16](https://tex.z-dn.net/?f=a%3D16)
The value of "a" in the given system of equations is 16
Therefore a=16
Therefore equation (2) becomes
12x-8y=2(16)
12x-8y=32
