Solve the following equation, answer as a reduced, mixed number. Then place the correct number in the box provided. 4(2x -3) + 8(x - 4) = 2(2x + 6

Answers

Answer 1
Answer:

Answer:

4 2/3

Step-by-step explanation:

4(2x -3) + 8(x - 4) = 2(2x + 6)

Distribute

8x -12 + 8x -32 = 4x +12

Combine like terms

16x - 44 = 4x+12

Subtract 4x from each side

16x-4x-44 =4x-4x+12

12x-44 = 12

Add 44 to each side

12x-44+44 = 12+44

12x = 56

Divide each side by 12

12x/12 = 56/12

x = 14 / 3

Changing to a mixed number

x = 4 2/3

from 40 bulbs tested by a quality controller, 3 are faulty calculate the expected number of faulty bulbs in a box of 500

Answers

Out of 40 bulbs, 3 were faulty.

3/40 were faulty

out of 500 bulbs, 'x' were faulty.

x/500 were faulty

(3)/(40) = (x)/(500)
cross multiply
40x=1500
Divide both sides by 40
x=37.5
Since you can't have .5 of a bulb, lets round up to 38
Answer=38 bulbs
