Find the common difference of the sequence shown.1/2,1/4 , 0, ...
a.-1/8
b.-1/4
c.-1/2

Answers

Answer 1

Answer: 1/2 , 1/4, 0

Find the common difference:

Rules in subtracting fraction
1) make sure the each fraction has a common denominator
2) if they have different denominators, find each least common multiple.
3) multiply the fraction by the lcm. apply the lcm to both numerator and denominator

1/4 - 1/2
1/4 - (1/2 * 2/2)
1/4 - 2/4 = 1-2/4 = -1/4

0 - 1/4 = -1/4

The common difference is B. -1/4

Answer 2

Answer: $(1)/(2) -(1)/(4) =(2)/(4) -(1)/(4) =(1)/(4)\n\n(1)/(4) -0 =(1)/(4)$

The common difference of the sequence is b. -1/4.

PLEASE HELP I WILL GIVE BRAINLIEST TO SAMPLE RESPONSE OR BEST ANSWER!The equation that represents the canned goods order is
24x + 4y = 384, where x = number of minutes spent
producing fruit cans, and y = number of minutes
producing vegetable cans.
If the vegetable assembly line runs for 3 minutes, how
many minutes would the fruit assembly line need to run to
complete the order of 384 cans? Explain

Answers

Answer:

8 minutes.

Step-by-step explanation:

24x + 64y = 384, that represents the canned goods order .

where x = number of minutes spent producing fruit cans,

and y = number of minutes producing vegetable cans.

If the vegetable assembly line runs for 3 minutes, then put y=3 in equation we get

Therefore, the fruit assembly line need to run to complete the order of 384 cans in 18 minutes.

Answer:

Substitute 3 into the equation for y. Solve for x and find that x = 8. So if cans of vegetables are processed for 3 minutes, fruit needs to be processed for 8 minutes to complete the 384-can order.

Step-by-step explanation:

How do you do this and what’s the solution?
