How many solutions does 8p + 1 = 4p +2 have?

Answers

Step-by-step explanation:

8p + 1 = 4p + 2

8p - 4p = 2 - 1

4p=1

4p/4p=1/4p

p=0.25

The equation 8p + 1 = 4p + 2 have one solution which is p = 0.25.

What is an Equation?

Equations are mathematical statements where we write two expressions which is equal to each other. There will be a left hand side and a right hand side on either sides of an equation.

The main classes of equations in algebra are linear equations and polynomial equations. On these include quadratic equations, cubic equations, differential equations and so on.

We have the expressions 8p + 1 and 4p + 1 equal to each other.

8p + 1 = 4p + 2

Subtracting the term 4p on both sides, we get,

8p + 1 - 4p = 4p + 2 - 4p

4p + 1 = 2

Subtracting both sides with 1,we get,

4p + 1 - 1 = 2 - 1

4p = 1

Dividing both sides by 4, we get,

p = 1/4

p = 0.25

Hence there is one solution to the equation 8p + 1 = 4p + 2 which is p = 0.25.

The Alvarado family went out for supper last week. The meal cost $65.92.
.
The sales tax is 7% of the meal.
The tip was 20% of the meal.
There are 4 people in the family.
What was the cost per person for the meal, including sales tax and tip?
A. $84.64
B. $21.16
C. $14.11
D. $16.48

Answers

The correct answer is $21.16

Explanation:

The first step to solve this mathematical problem and find the correct answer is to calculate the cost of the sales tax and the tip by using the cost of the meal. The process is shown below:

1. Calculate the sales tax (7%)

7% of $65.92

65.92 / 100 = 0.6592

0.6592 x 7 = 4.6144 (Money on the sales tax)

2. Now, add the initial cost of the meal to the taxes and calculate the tip (20%)

$65.92 + $4.6144 = $70.5344

20% of $70.5344

70.5344 / 100 = 0.705344

0.705344 x 20 = 14.10688 (Money on tip)

Now, let's add the three values to calculate the total cost of the meal

$65.92 + $4.6144 + $14.10688 = $84.64128

Finally, divide the price into 4 because 4 people will pay

$84.64128 / 4 = $21.16032 which can be simplified as $21.16

Step-by-step explanation:

In order to solve this seemingly simple problem, you need to remove the decimal from 1.92 and act like it isn't there. Once you've divided 192 by 3 to get 64, you can put the decimal place back where it belongs and get your final answer of 0.64.

After his initial reaction, Mr. Evil has some time to think. He calls you on the phone with a new plan. “OK,” he says. “I don’t need to be able to tunnel to the bank today, but I need to be able to do it within the next 30 years. I have access to a house that is much closer. I need to know if it will be close enough.” What do you need to know in order to answer him? Under what conditions would this new property be close enough to the bank????????? HELPPPPPPPPPPPPPPPPP

Answers

Answer:

um.

Step-by-step explanation:

So he is asking, abstractly, from lack of context, if his house is close enough to the bank?

This makes little sense, abstractly. I mean, does he live in a post-apocalyptic Mad Max setting where he needs explosives and men or perhaps a frozen-over world where he needs large steam-powered engines to drill through the permafrost? It makes little substantiated sense.

So you need to know how much money he has, his charisma level, and the setting of the plot.

If the property is next to the bank, then it would be, by far, close enough to the bank.

Kimberly is deciding between two cell phone plans. The first plan has a $50 sign-up
fee and costs $20 per month. The second plan has a $30 sign-up fee and costs $25 per
month. After how many months will the costs be the same for the two phone plans?

Answers

Answer:

2month and 2 weeks

Step-by-step explanation:

We are told that the first plan has a $50 sign-up

fee and costs $20 per month.

let the number of months be x, and the total cost be y

y=20x+50---------1

The second plan has a $30 sign-up fee and costs $25 per

let the number of months be x, and the total cost be y

y=30x+25---------2

Equate the two equations we have

20x+50=30x+25

solve for x, collect like terms

50-25=30x-20x

25=10x

divide both sides by 10

x= 25/10

x=2.5 months

x= 2month and 2 weeks

Step-by-step explanation:

Craig multiplies 2x + 4y = 16 by 2 and then subtracts the equations. He finds the result is a contradiction, so there is no solution. The correct option is B.

What is system of equations?

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between two or more variables.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

Given equations are 2x+4y=16 and 4x+8y=−16. The equations will be solved as below,

2x+4y=16

4x+8y=−16

Multiply the first equation by 2 and solve,

4x+8y=16

4x+8y=−16

Therefore, Craig multiplies 2x + 4y = 16 by 2 and then subtracts the equations. He finds the result is a contradiction, so there is no solution. The correct option is B.

Q4a) yes, the equation is a linear function as it is a straight line; it has a slope of 2 and a y intercept of (0,2).
b) no, the equation isn't a linear function as it takes the form of a parabola (x^2-bx).

Q5) y=x+6, y= x^2+6 and y=2x+6 go through the point of (0,6). This is because, if you substitute 0 for x in all the three equations, y is always equal to 6.

Q6) the line is a linear function because it is a straight line that has a slope and a y intercept. To figure out the equation of the line, you have two points, (-2,0) and (0,3). To no the gradient, you do 3-0 divided by 0+2, which is 3/2. Then, you choose on random point and substitute it in y=mx+b

3= 3/2*0+b

So you get 3=b

So, the equation of the line is y= 3/2x+3

Add 9 to both sides of the equation, and divide by the coefficient of B.
