help me please and thanks!

Answer:

the correct answer is B 2x + 1 = 7

Answer:

x = 2

is not a solution for (B)

as 2(2) = 4

4 + 1 = 5

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:

option- A

Step-by-step explanation:

the typical value is greater in set B . The spread is greater is set A.

Answer: If t would be the number of days, d the distance they built and x the total they built, then the relationship would be x = td.

Step-by-step explanation: If they build a certain amount of road every day, then in two days, they're gonna build twice that much road, in three days triple, etcetera. Therefore you just need to multiply the amount of days they work with the amount of road they build in a day.

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.

Answer:

Hence, 70 people out of 100 who had attained the previous year

Step-by-step explanation:

If this is completely proportional, you'd make the formula

[tex] \frac{420}{600} = \frac{x}{100} [/tex]

Cross multiply

[tex]42000 = 600x[/tex]

Then we just divide by 600

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.

Answer:

30/38 = 15/n

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

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

volume= (2.5)(4)(6)

volume= 60

The amount of glass used is equivalent to the surface area of the glass surfaces.

As the problem is specifying the top of the aquarium is open, we'll assume that it is not included for the surface area calculations.

[tex]A=2 (2.5 \times 4) +2(6\times4)+(6\times2.5)[/tex]

The first term represents the area of two 2.4 x 4 faces of the aquarium. The second term is the area for the two 6 x 4 faces. The last term is for the 6 x 2.5 base of the aquarium, and it is not multiplied by 2 as we are not including the top of the aquarium.

[tex]=2 \times 10 + 2\times24 + 15[/tex]

[tex]=83 \text{ ft}^2[/tex]

The aquarium has a surface area of 83 square feet. Hence, 83 square feet of glass was used to build the tank.

Answer:

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
