Answer:

no C

(25×4)+15

because out of 25 students each students brought 4 stamps which means 25×4 and their teacher brought 15 which is added .

Answer:

C

Step-by-step explanation:

there are 25 students and they EACH brought 4. Each means you multiply. so we have 25x4. then Mr. Miller brought 15 more stamps so we need to add that to the equation. so we have (25x4) because that is separate from the 15.

(25x4)+15

Answer:

Your problem will require you setting up 2 algebraic equations. First, you should.

Let A represent the number of adult tickets

Let S represent the number of student tickets

The first equation will be:

A+S = 1,215 tickets

The number of adult tickets plus the number of student tickets equals 1,215 tickets

The second equation will be:

5.00A+1.00S=$2,591

The price and number of adult tickets plus the price and number of student tickets equals $2,591.

I hope this has made the problem easier to understand. I hope you are able to solve the problem from here. If you can not solve the problem from here, I will be more than happy to further assist you.

Step-by-step explanation:

You have two unknowns, two variables, therefore you need to have at least two equations in this word problem in order to find a solution. Let's review the info you are given:

The price of an Adult ticket: $5

The price of a Student ticket: $1

The two variables are: the number of Adult tickets sold (you can use variable "A"), and the number of Student tickets sold (use variable "S").

The other info you are given is the total number of tickets sold: 1,215 tickets. Use this to make your first equation: the number of adult tickets plus the number of student tickets equals 1,215.

You are also told how much money was collected: $2,591. That means, $5 from every Adult ticket and $1 from every student ticket. We don't know how many of each ticket, but we assigned variables A and S to stand in for this unknown info. The money made from all the adult tickets would be the price of the adult ticket times how many adult tickets sold (5 times A), and the money made from all the student tickets would be the price of the student ticket times how many student tickets sold (1 times S). Use this to make your second equation, which says that all the money collected from all the tickets (5 times A in addition to 1 times S) is (=) 2,591.

Now you have two equations, each equation has two variables. To solve, go back to the easiest equation (the first one) and isolate one of the variables. By isolate I mean get it on one side of the equation by itself. Since in this case these variables are being added together, you have to do the opposite of addition, which is of course subtraction. To do this, you will have to subtract the other variable ON BOTH SIDES of the equation. So, say we want to isolate the variable A, we will subtract S from both sides. Well, S minus S is zero, so now A is isolated, meaning the left side of the equation is just A = ...  Now you want to subtract the S on the other side. Remember that whatever you do to one side you must do to the other.

Now that you have your equation re-worked to show A = ..., you need to "plug it into" the second equation. What I mean is, you need to substitute instead of A, put in this equation. Then you will have one equation with one variable which you can solve! Remember the rules of equations, to do work in parenthesis first, the multiply or divide, then add or subtract. You will be able to solve for S.

Once you have found S (the number of student tickets sold), you can easily find A (the number of adult tickets sold) by going back to that first equation and subtracting your value of S from 1215.

Answer:

To make estimates, we usually round the numbers the nearest integer.

Since 1.9 is closest to 2 than it is to 1, the nearest integer of 1.9 is 2.

Similarly, since 4.4 is closest to 4 than it is to 5, the nearest integer of 4.4 is 4.

Now, to estimate the area of the farm, we are going to multiply our two integers:

Estimated Area of the Farm= x

Since 8 is between 4 and 10, we can conclude that the best estimate of the area of the farm is: between 4 and 10

Answer:

[tex]2\frac{7}{12}[/tex] kg of plant food

Step-by-step explanation:

The second question doesn't have choices, so I'll answer the first question only.

In order to know how much plant food Sheldon has, you have to subtract [tex]1\frac{2}{3}[/tex] kg of plant food used for the strawberry plants from [tex]4\frac{1}{2}[/tex] kg of plant food. Then, [tex]\frac{1}{4}[/tex] kg will be subtracted from the difference.

Let's convert both fractions into improper fractions first, so it will be easier to subtract.

Now, let's subtract.

Next, you have to subtract [tex]\frac{1}{4}[/tex] kg of plant food used for the tomato plants from the remaining plant food of [tex]\frac{17}{6}[/tex] kg.

Let's subtract again.

Therefore, Sheldon has [tex]2\frac{7}{12}[/tex] kg of plant food left.

Answer:

For example, the conjugate of 0 + √3 is 0 - √3, the conjugate of -√3 is √3, and the conjugate of 2 - 5√3 is 2 + 5√3.

Step-by-step explanation:

The complex conjugate of the root x = 3i will be x = -3i.

The complex conjugate of a complex number is the number that has equal real and imaginary parts that are opposite in sign but equal in magnitude.

A given complex function is x = 3i

As we know that the complex conjugate function is one in which the imaginary part of the function becomes negative.

The complex conjugate function will be:-

x = -3i

Therefore the complex conjugate of the root x = 3i will be x = -3i.

Answer: C

Step-by-step explanation:

Given

[tex]\frac{5}{4}(a-8)=\frac{2}{3}[/tex]

Multiply both sides by (4/5)

[tex]\frac{5}{4}(\frac{4}{5})(a-8)=\frac{2}{3}(\frac{4}{5})[/tex]

[tex]a-8=\frac{8}{15}[/tex]

Add 8 on both sides

[tex]a=\frac{8}{15} + \frac{120}{15}[/tex]

[tex]a=\frac{128}{15}[/tex]

[tex]a=8\frac{8}{15}[/tex]

Answer:

6 students

Step-by-step explanation:

Given data

Base charge= $40

charge per student = $30

We are told that for s number of student the tutor charged 220

The expression for the tutor's charges is given as

y= 40+30s

Therefore for y= 220, let us find s, the number of students

220=40+30s

220-40= 30s

180=30s

divide both sides by 30

s= 180/30

s= 6

Hence there are 6 students

Answer:

60

Step-by-step explanation: Simplifying

15x + 30y = 60

Solving

15x + 30y = 60

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-30y' to each side of the equation.

15x + 30y + -30y = 60 + -30y

Combine like terms: 30y + -30y = 0

15x + 0 = 60 + -30y

15x = 60 + -30y

Divide each side by '15'.

x = 4 + -2y

Simplifying

x = 4 + -2y

Answer:

15 ( x + 2y)

Step-by-step explanation:

First 15x + 30y

(3x5)x + (2 x 3 x 5)y

3 x 5 (3x5x/3x5 + 2 x 3 x 5y/3x5)

3 x 5 (x + 2y)

15 (x + 2y)

Answer:

(-4,9)

Step-by-step explanation:

substitute the given value for y into the first equation

x-5(-2x+1)=-49

distribute

x+10x-5=-49

add like terms

11x-5=-49

add 5 to both sides

11x=-44

divide both sides by 11

x=-4

now plug x into into the second equation

y=-2(-4)+1

y=8+1

Answer: x= 4.5, y=3.6, z=6.5

Step-by-step explanation:

To find : x, y and z.

First label the triangle as A,B,C and D (as in the picture below).

ΔABC , ΔACD and ΔABD both are right triangles.

In ΔABC ,

[tex]y^2=3^2+2^2[/tex]        [By Pythagoras theorem]

[tex]\Rightarrow\ y^2=13\\\\\Rightarrow\ y=\sqrt{13}\approx3.6[/tex]

In ΔACD ,

[tex]AD^2=3^2+x^2\\\\\Rightarrow\ AC^2=9+x^2 \ \ ...(i)[/tex]        [By Pythagoras theorem]

In ΔABC ,

[tex]y^2+AC^2=(2+x)^2\\\\\Rightarrow\ AC^2=(2+x)^2-y^2\ \ ...(ii)[/tex]

From (i) and (ii), we get

[tex]9+x^2=(2+x)^2-y^2\\\\\Rightarrow\ 9+x^2=4+x^2+4x-(3.6)^2\\\\\Rightarrow\ 9=4+4x-12.96\\\\\Rightarrow\ 4x=9-4+12.96\\\\\Rightarrow 4x= 17.96\\\\\Rightarrow\ x=\dfrac{17.96}{4}\\\\\Rightarrow\ x=4.49\approx4.5[/tex]

Z = 2+x= 2+4.5 =6.5

Hence, x= 4.5, y=3.6, z=6.5
