8 5/12 - 6 3/4 (be sure to simplify if necessary)

Answer:

Im very confused

1) 9 (whole)

2) 8 (whole)

3) 38.08 (part)

4) 24 (whole)

A = part

B = whole

C = part

D = whole

Answer: B=$3.75×3

Explanation: we want the full price of the Big Dipper so the equation will equal to B, there were 3 friends that split the bill $3.75 each so if we multiple 3.75 by 3 we will get the total cost of the Big Dipper which is $11.25

The solution is: b=$3.75×3, the equation models the problem, when b represent the total cost of a Big Dipper sundae.

Here, we have,

given that,

Regan and her friends shared a Big Dipper sundae at Skylight Ice Cream Shop.

The 3 of them split the bill, and each person paid $3.75.

Explanation:

we want the full price of the Big Dipper so the equation will equal to b, there were 3 friends that split the bill $3.75 each

so if we multiple 3.75 by 3

we will get the total cost of the Big Dipper which is $11.25

i.e. 3.75 × 3

    = 11.25

So,  b=$3.75×3, the equation models the problem, when b represent the total cost of a Big Dipper sundae.

Answer:

A) X = 4 - 7Y

B) Independent Variable: Y, Dependent Variable: X

Step-by-step explanation:

Explanation for A:

We form a simple equation, knowing that if he drinks y liters each day after one week it would be 7Y. Then, we'd subtract it from 4

So equation would be X = 4 - 7Y

Explanation for B:

The independent is Y because doesn't change or get affected by another variable, and the dependent variable is X because depending on the value of Y, X will change accordingly.

Answer:

30/38 = 15/n

30/15 = 2, so n = 38/2 = 19

Answer16⋅x+4

Step-by-step explanation:

i can not use parentheses so the sum of 4 +4 and the product of 16 and x

so 16 and x would be 16⋅x and sum of 4 would be +4 so 16⋅x+4

Answer:4+16x

Answer:

3 x 3/5 = 9/5 or 1 4/5

Step-by-step explanation:

First convert 3 to a fraction

3/1 x 3/5

Then multiply the denomenators and the numerators

3 x 3 = 9

1 x 5 = 5

9/5 is the answer

Answer:

n = 24

Step-by-step explanation:

first put the equation into fraction form and cross multiply:

12/18 = n/36

12(36) = n(18)

432 = 18n

now isolate the variable:

432/18 = 18n/18

24 = n

Answer: 70%

Step-by-step explanation:

The total answers count 30 - it's 100%, so to get a 1% value, divide 30 by 100 to get 0.30. Next, calculate the percentage of 21: divide 21 by 1% value (0.30), and you get 70.00%

Answer: k - 15 = 33

Step-by-step explanation:

So basically you just translate the problem into math form. 33 is a #, is is an = sign so, 33 = so far. Then 15 is less than k, which is not 15 - k but k - 15. There's a difference. Say k is 30, so 30 - 15 and not 15 - 30. So then you have 33 = k - 15, then I just switched it around to look better and done.

k-15=33

Step-by-step explanation:

#18 complementary

3x +45 = 90

3x + 45-45 = 90 -45

3x = 45

Divide both sides by 3

3x/3 = 45/3

x = 15

#20 supplementary

2x + 3x + 25 = 180

5x + 25 = 180

5x + 25 - 25 = 180 -25

5x = 155

Divide both sides by 5

5x/5 = 155/5

x = 31

#15 - vertical

4x - 25 = 75

4x - 25 + 25 = 75 + 25

4x = 100

Divide both sides by 4

4x/4 = 100/4

x = 25

#16 - complementary

4x + 2x = 90

6x = 90

divide by 6 each side

x = 15

#19 complementary

x -20 + x = 90

2x -20 = 90

2x -20 + 20 =90 +20

2x = 110

Divide both sides by 2

2x / 2 = 110/2

x = 55

Step-by-step explanation:

The solution of for the system of linear equations shown in the graph is x = -1/2 and y = 3/2.

Given points of two lines:-

Line 1 : (0,0) , (1,-3)

Line 2 : (0,2) , (-1,1)

Let the Equation of Line 1 : y = mx + c

m = (-3-0)/(1-0) = -3/1 = -3

Putting (0,0) in  y = mx + c, we get

0 = -3*0 + c

0 = 0 + c

c = 0

Hence,

Equation of Line 1 : y = -3x or y + 3x = 0  ...(1)

Similarly, we can find,

Equation of Line 2 : y = x + 2 or y - x = 2  ...(2)

(1) - (2),

4x = -2

x = -2/4 = -1/2

Putting the value of x in (2), we get,

y - (-1/2) = 2

y + 1/2 = 2

y = 2-(1/2)

y = 3/2

9 the rolls will result in a sum greater than 10 if the experiment is repeated 108 times.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36.

As, Expected number of outcomes = theoretical probability * number of trials

Expected number of outcomes = 3/36 x 108

                                                    = 9

Thus, the required value is 9.
