Remember to do the same thing to both sides

use distributive prpoerty which is
a(b+c)=ab+ac so
pemdas
multiplication
8(x+1/4)=8x+8/4=8x+2
3(6x-9)=18x-27

now we have7x+8x+2=18x-27-8
add like terms
15x+2=18x-35
subtract 15x from both sides
2=3x-35
add 35 to both sides
37=3x
divide both sides by 3
37/3=x
12 and 1/3=x

Answer:

Option D. 50 ft

Step-by-step explanation:

we know that

The area of the figure is equal to the area of three rectangles

so

A=18x+(48-36)(32-11)+(18)(32)

A=18x+(12)(21)+(18)(32)\\A=18x+828

Remember that the area is given

A= 1,728\ ft^2

so

18x+828=1,728

solve for x

18x=1,728-828\\18x=900\\x=50\ ft

A manufacture inspects 800 light bulbs and finds that 796 of them have no defects. What is the experimental probability that a l
BartSMP [9]

Answer:

The experimental probability that a light build chosen at random has no defects is 99.5 % or P(A)=0.995.

Step-by-step explanation:

let S be the sample space for the inspection of the light bulbs.

Therefore, n(s) = 800

let ' A ' be the event of no defects bulbs.

Therefore, n(A) = 796

Now the Experiment probability for a light bulb chosen has no defects will be given by,

P(A)=\dfrac{n(A)}{n(S)}

Substituting the values we get

P(A)=\dfrac{796}{800}=0.995

The experimental probability that a light build chosen at random has no defects is 99.5 % or P(A)=0.995.
