I would solve the first equation for x and then sub that value into x in the second equation. That's the easiest way. x - 2y = 3 solved for x is x = 2y+3. Now sub that in for x in the second equation: 5(2y+3)+3y=2 and 10y + 15 + 3y = 2. 13y = -13, and y = -1. Now sub that y value into either equation to solve for x: x = 2(-1) + 3 gives us an x value of x = 1. Therefore, your solution to this system is (1, -1), first choice above.
Digit 3 has a value of 3*10000
Let's solve for p.
x3xp=x5
Step 1: Divide both sides by x^2.
px2x2=x5x2
p=x3
Answer:
p=x3
Answer:
![h=\frac{6V}{\pi d^2}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B6V%7D%7B%5Cpi%20d%5E2%7D)
Step-by-step explanation:
we have
![V=\frac{\pi d^2h}{6}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B%5Cpi%20d%5E2h%7D%7B6%7D)
Solve for h
That means ----> isolate the variable h
step 1
Multiply by 6 both sides
![6V=\pi d^2h](https://tex.z-dn.net/?f=6V%3D%5Cpi%20d%5E2h)
step 2
Divide by
both sides
![h=\frac{6V}{\pi d^2}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B6V%7D%7B%5Cpi%20d%5E2%7D)
C. 01/100. .01 is in the hundredths place. So you put 2 0's on the denominator.
