Fae = 8x. acd =11x +4

solve for x using
128 = (180-11x-4) + (180-8x)
128=356-19x
19x =356-128
x=228/19
x=12 sub back into

Answer:

4.5 inches

Step-by-step explanation:

We are given the formula:

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

Plug in the the radius (3) and volume (127.23):

127.23 = $3.14(3)^{2} h$

Square the 3 :

127.23 = $3.14(9)h$

Multiply the pi & volume:

127.23 = 28.26h

Divide both sides by 28.26:

127.23 ÷ 28.26 = 28.26h ÷ 28.26

h = 4.5021231...

I hope this helps!

What does x represent in the equation is -2(bx-5)=16 if b is 3

uranmaximum [27]

Answer:

x = - 1

Step-by-step explanation:

Given

- 2(bx - 5) = 16 ← substitute b = 3

- 2(3x - 5) = 16 ( divide both sides by - 2 )

3x - 5 = - 8 ( add 5 to both sides )

3x = - 3 ( divide both sides by 3 )

x = - 1

A blueprint uses a scale factor of 3 inches = 2 feet. What is the area on the blueprint of a 3,500 square foot house in inches?

lyudmila [28]

Answer:

7875 square inches

Step-by-step explanation:

4ft^2 = 2ft * 2ft

4ft^2 = 3in * 3in

4ft^2 = 9in^2

For 3,500 square foot

3,500 square foot = x

Divide bith expressions

4/3500 = 9/x

4x = 9 * 3500

4x = 31500

x = 31500/4

x = 7875 square inches

Hence the area of the house in inches is 7875 square inches
