Answer:

6.4

Step-by-step explanation:

#1. 3x+1.5=2.5x+4.7

#2. subtract by 1.5 on both sides

#3. 3x=2.5x +3.2

#4. then subtract 2.5x on both sides because you need all the x'x on one side

#5. .5x= 3.2

#6. then you divide but you should bring the decimal to the right once on both sides

#7. x=6.4

Blababa [14]

Answer: V = $100\pi$ $in^{3}$ (third option)

Given Information:

V = $\frac{1}{3}\pi r^{2} h$ <-- volume formula.
r = 5
y = 13
<em>h = ?</em>

To find h...

h, r, and y make a right triangle.
h and r are the two legs, y is the hyptenuse.
$h^{2} + r^{2} = y^{2}$
$h^{2} + 5^{2} = 13^{2}$
$h^{2} + 25 = 169$
$h^{2} = 144$
h = 12

Use formula:

V = $\frac{1}{3}\pi r^{2} h$
V = $\frac{1}{3} \pi (5)^{2} (12)$
V = $\frac{1}{3} \pi (25)(12)$
V = $\frac{1}{3} \pi (300)$
V = $100\pi$

Having a problem solving for h in this algebra problem. A=1/2h(B+b); A=35, B=6, b=1 <br> So h=?

ivann1987 [24]

35 = 1/2h (6+1)
35 = 1/2 h + 7
28 = 1/2h
14 = 1h
14 = h
