Answer:

x = 8

Step-by-step explanation:

3x - 5 = 2.5x + 3 - (x - 4)

open parentheis

3x - 5 = 2.5x + 3 - x + 4

3x - 5 = 1.5x + 7

subtract 1.5x from both sides of the equation

3x - 1.5x - 5 = 7

1.5x - 5 = 7

add 5 to both sides of the equation

1.5x = 7 + 5

1.5x = 12

divide both sides of the equation by 1.5

1.5x/1.5 = 12/1.5

x = 12/1.5

x = 8

V=pir^2h solve this equation for h

Nady [450]

Since we are solving for h, the equation:

V = πr²h

...divides πr² to the other side. Thus, it becomes....

$\frac{V}{ \pi r^2}$ = h

Which can be rewritten as....

h = $\frac{V}{ \pi r^2}$

Use this picture to solve for X

Zepler [3.9K]

Answer:

x=2

Step-by-step explanation:

i would set up a system of equation using the pythagorean theorem:

1^2+x^2=z^2

4^2+x^2=y^2

Add up these equations to get:

17+2x^2=y^2+z^2

But notice that

y^2+z^2=5^2

So you can substitute

17+2x^2=25

2x^2=8

x^2=4

x=2
