Answer:  2 & 2/4 which is choice A

Work Shown:

1/4 = 0.25

2/4 = 0.5

3/4 = 0.75

2 & 3/4 = 2 + 3/4 = 2 + 0.75 = 2.75

5 & 1/4 = 5 + 1/4 = 5 + 0.25 = 5.25

Subtract the values:

5.25 - 2.75 = 2.5

Then convert back to a mixed number

2.5 = 2 + 0.5 = 2 + 2/4 = 2 & 2/4

Optionally you can reduce that 2/4 into 1/2, but it appears your teacher has chosen not to.

If a couple were planning to have three​ children, the sample space summarizing the gender outcomes would​ be: bbb,​ bbg, bgb,​
MaRussiya [10]
There are two choices for each child: overweight (o) or underweight (u). So if the first child is o the next can be o or u. If the first is u the second can be o or u. This gives four possibilities. Here the first child is the letter noted first and the second is the one listed second:
OO
OU
UO
UU

There are 4 outcomes and if each is equally likely then the probability of each is 1/4. Thus the probability of UU is 1/4

The probability of one underweight and one over weight is 1/2 because in two of the outcomes listed above there is one O and one U (namely OU and UO). Since there are 4 outcomes the probability is 2/4 = 1/2

9x-8(x-6)=52 what is the answer
Effectus [21]

Answer:

x = 4

Step-by-step explanation:

Step 1: Write equation

9x - 8(x - 6) = 52

Step 2: Solve for <em>x</em>

  1. Distribute -8: 9x - 8x + 48 = 52
  2. Combine like terms: x + 48 = 52
  3. Subtract 48 on both sides: x = 4

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

9(4) - 8(4 - 6) = 52

36 - 8(-2) = 52

36 + 16 = 52

52 = 52
