How Is Adding Two Negative Fractions Like Adding Two Positive Fractions.ples Help Me

Answers

Answer 1

Answer:

A negative fraction subtracted from another is the same thing as adding the positive complement of that fraction. Make the denominators (the bottom of the fraction) the same, if they are not already. You can only add halves to halves or quarters to quarters or tenths to tenths and so on.

Each day, a bakery makes 50 loaves of
wheat bread. If that amount is 20%
of all the bread that they bake, how
many loaves do they bake each day?

Answers

If 20% is 50 loaves, we would first write it like this: 20/100 = 50/x. We would then use the butterfly method to get 20x = 5,000. To isolate the variable, we would divide both sides by 20. This gets our answer of 250 loaves a day.
50=20%
x =100%
50*100=5,000
20*x=20x
5,000/20=250

Answer: 250 loaves of bread

Step-by-step explanation:

Fx equals 4x-6

Answers

the answer is A because the angle AHD is not 30 degrees it is a 90 degrees angle

Answer:

He knows this because if the angles are added together the have to equal 180 degrees because a line equals 180 and lines make up a triangle

Step-by-step explanation:

But the answer is A because x cannot equal 30  because it askes the angles not x so AHD is 30 also you can tell by looking that its not that big.

here are some numbers 2 9 14 36 40 what number is a multiple of 12 which number is a prime number which number is a factor of 64

Answers

Answer:  36 is a multiple of 12

2 is a prime number.

2 is a factor of 64

Step-by-step explanation:

12 × 3 =36, so 12 is one of the factors.

2 is the only even prime number. All other even numbers are multiples of 2.

9 is not a prime number. 3 × 3 = 9

2 is a factor of 64.  2 × 32 = 64  None of the other numbers given can divide evenly into 64, so they are not factors of 64.

Two groups performed an experiment separately by tossing a coin in the air. Group P performed 50 trials and group Q performed 100 trials. Each group recorded the results in the table below:

Group Heads Tails
P 35 15
Q 53 47
What conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails? (5 points)

Group of answer choices

The experimental probability is closer to the theoretical probability for group Q than group P.

The experimental probability and the theoretical probability for group Q is the same.

The experimental probability and the theoretical probability for group P is the same.

The experimental probability is closer to the theoretical probability for group P than group Q.

Answers

Answer:

Are you still in the test? If so I am guessing (not 100% sure) the answer is A.

Step-by-step explanation:

A. The experimental probability is closer to the theoretical probability for group Q than group P.

This may be the answer because, 100 trials is twice the amount of trials in the experiment of p. Theoretically people would think 100 trials is better because more results concludes to an more accurate average. The probability  is better for p because the smaller amount of trials means no changes within a project. You can control the variables.

Hopefully this is right!
