Answer: 200 bulbs will not be defective.
Step-by-step explanation:
The ratio of defective bulbs to good bulbs produced each day is 2 to 10. This ratio can also be expressed as 1 to 5 by reducing to lowest terms.
The total ratio is the sum of the proportions.
Total ratio = 1 + 5 = 6
This means that if n bulbs is produced, the number of defective bulbs would be
1/6 × n
The number of non defective would be
5/6 × n
Since n = 240, then the number of bulbs that will not be defective is
5/6 × 240 = 200 bulbs
Answer:
Refer to the picture above.
Answer:
a = −bx+7x−4 over x
Step-by-step explanation:
solve for a:
7+ax−5x=3+2x−bx
add 5x to both sides:
ax−5x+7+5x=−bx+2x+3+5x
ax+7=−bx+7x+3
add -7 to both sides:
ax+7+−7=−bx+7x+3+−7
−bx+7x−4
lastly divide both sides by x.
