Find two fracrions in between 2/7 and 3/7 whose numerator and denominator are whole numbers

Answer:

f=1

Step-by-step explanation:

Let start off with doing -f plus 4f which gives you 3f. The equation would now be 2+3f=8-3f. Add 3f so you can cancel out the -3f and add the 3f to the other 3f. Now your equation is 2+6f=8. Cancel out do by doing -2. (Don't forget to to it to the 8 also.) Now your equation is 6f=6. Divide 6 from both sides to get 1. (You divide because you want to get f alone.

Answer: 3

Step-by-step explanation:

Let the smaller number be y.

Since the difference of two numbers is 5,then the larger number will be: y+5

The sum of three times the larger number and twice the smaller number is 30. This can be written as:

3(y+5) + 2y = 30

3y + 15 + 2y = 30

5y + 15 = 30

5y = 30 - 15

5y = 15

y = 15/5

y = 3

The smaller number is 3

Answer:

Mean of this data set is 43.7857

the median of this data set is 42

Step-by-step explanation:

The complete question is:

Fifteen seventh graders were randomly selected to see how many pushups in a row they could do. Their data are shown. A. b. 45, 40, 36, 38, 42, 48, 40, 40, 70, 45, 42, 43, 48, 36

a. Determine the mean of this data set.

b. Determine the median of this data set.

Given:

Data:

45, 40, 36, 38, 42, 48, 40, 40, 70, 45, 42, 43, 48, 36

To find:

a) Mean

b) Median

Solution:

a)

The formula to find Mean is :

Mean = Sum of all the values / Total number of values

          = ∑ x / n

Here there are total 14 values so n = 14

Now lets find sum of all the values

∑ x =  45 + 40 + 36 + 38 + 42 + 48 + 40 + 40 + 70 + 45 + 42 + 43 + 48 + 36

     = 613

Now compute Mean:

Mean = ∑ x / n

          =  613 / 14

         = 43.785714

Mean = 43.7857

b)

The formula to find Median is:

Since there are 14 values in the data this means the data has even number of values. So to compute the median of even number of values:

First put the values in order.

Second, find the middle pair of values in data

Third, find the value that is half way between them i.e. by adding the two middle pair values and dividing the result by 2

45, 40, 36, 38, 42, 48, 40, 40, 70, 45, 42, 43, 48, 36

Ordering the values :

36, 36, 38, 40, 40, 40, 42, 42, 43, 45, 45, 48, 48, 70

Find the middle two numbers:

42, 42

We can see that both are same values so median value is 42 but to follow the above steps:

Now add these two numbers and divide the sum by 2:

42 + 42 = 84

84/2 = 42

So the median of this data set is 42

Well your using absolute value and everything in absolute value is positive so you get rid of the negative.

Step-by-step explanation:

So you distribute the negative into the absolute value equation . And it leaves you with

|-1+5a|=29 now you can solve

your subtract your -1 from both sides bc you are solving for a

that gives you

5a=30 then you divide 5 divided by 30 is what 6 so that’s your answer

Answer:

n = m r - r t

Step-by-step explanation:

Solve for n:

m = n/r + t

Hint: | Reverse the equality in m = n/r + t in order to isolate n to the left hand side.

m = n/r + t is equivalent to n/r + t = m:

n/r + t = m

Hint: | Isolate terms with n to the left hand side.

Subtract t from both sides:

n/r = -t + m

Hint: | Solve for n.

Multiply both sides by r:

Answer: n = m r - r t

Step-by-step explanation:

To expand the bracket, [tex](2x - 3)^{2}[/tex] we will simply be multiplying the bracket by itself.

This will be the same as having [tex](2x - 3) \times (2x - 3)[/tex]

The first step in doing this is to multiply each of the values in the second bracket by the values in the first one.

[tex]2x \times 2x =4x^2[/tex]

[tex]2x\times -3 = -6x[/tex]

[tex]-3 \times 2x = -6x[/tex]

[tex]-3 \times -3 =9[/tex]

Once this is done, the next step is to group the like terms and evaluate the result.

[tex]4x^2 -6x-6x +9[/tex]

[tex]4x^2 -12x +9[/tex]

This is algebraic expression is the result of the expansion of [tex](2x - 3)^{2}[/tex] .

Based on the descending powers of x

a = 4

b = -12

c = 9

These are the coefficients of [tex]x^2[/tex]  and [tex]x[/tex] and also the last figure.

a + b + c = 4 -12 +9 = 1

Answer:

q= -4

Step-by-step explanation:

[tex]5q + 6 = 2 q- 2 + q[/tex]

Collect like terms and simplify

[tex]5q - 2q - q = - 2 - 6 \\ 2q = - 8[/tex]

Divide both sides of the equation by 2

[tex] \frac{2q}{2} = \frac{ - 8}{2} \\ [/tex]

Simplify

[tex]q = - 4[/tex]

The requried solution to the equation 5q + 6 = 2q - 2 + q is q = -4.

To solve the equation 5q + 6 = 2q - 2 + q, we need to simplify and combine like terms. Let's proceed step by step:

First, let's combine the q terms on the right side of the equation:

5q + 6 = 2q - 2 + q

Combining the q terms on the right side, we have:

5q + 6 = 3q - 2

Next, let's isolate the q term by moving all other terms to the opposite side:

To move the 3q term to the left side, we subtract 3q from both sides:

5q - 3q + 6 = -2

Simplifying the left side:

2q + 6 = -2

Next, let's isolate the constant term by moving 6 to the right side:

Subtracting 6 from both sides:

2q = -2 - 6

2q = -8

Finally, to solve for q, divide both sides by 2:

q = -8/2

q = -4

Therefore, the solution to the equation 5q + 6 = 2q - 2 + q is q = -4.
