If five bags of mulch covers 32 square feet, how many square feet could 16 bags cover?

Answer:

Part 1:

The solution set of the system of equations is x = 1, y = 1

Part 2:

The solution set is x = 1, y = 1

Part 3:

The similarity of the system of equations in Parts 1 and 2 is that they have the same solution set

The difference of the system of equations in Parts 1 and 2 is that they are arranged differently

Step-by-step explanation:

Part 1:

The system of equation is given as follows;

2·x + y = 3...(1)

x = 2·y - 1...(2)

The above system of equations can be written in terms of the variable, y, as follows;

For equation (1), we have;

y = 3 - 2·x

For equation (2), we have;

y = (x + 1)/2

From the attached graph created with Microsoft Excel, we have;

The solution set (the point of intersection) of the system of equations is x = 1, y = 1

To accurately find the common solution, we have;

(x + 1)/2 = 3 - 2·x

x + 1 = 2·(3 - 2·x) = 6 - 4·x

x + 1 = 6 - 4·x

x + 4·x = 6 - 1

5·x = 5

x = 5/5 = 1

x = 1

Therefore, y = 3 - 2·x = 3 - 2× 1 = 1, at the common solution

Part 2:

y = -2x + 3

x - 2y = -1

∴ x = 2y -1

y = -2(2y -1) + 3

y = -4y + 2 + 3

5y = 5

y = 1

x = 2y - 1 = 2 - 1 = 1

x = 1

The solution set is x = 1, y = 1

Part 3

The system of equations are similar in terms of their solution

The system of equations are different in terms of their arrangement

Answer:

X = 35

Step-by-step explanation:

5 + 100 = 7x + 30

5x + 100 - 100 = 7x + 30 - 100

5x = 7x - 70

5x - 7x = 7x - 70 - 7x

-2x = -70

-2x/-2 = -70/-2

x = 35

Answer:

Smallest length side = 12 ft

Middle length side = 28 ft

Longest length side = 32 ft

Step-by-step explanation:

Perimeter of ∆ = sum of all its length sides

Thus, we are given that:

Perimeter = 72 ft

Let x represent the smallest length side. Therefore:

Smallest length side = x ft

Middle length side = (2x + 4) ft

Longest length side = (3x - 4) ft

Thus:

(2x + 4) + (3x - 4) + x = 72

Solve for x

2x + 4 + 3x - 4 + x = 72

Collect like terms

2x + 3x + x + 4 - 4 = 72

6x = 72

Divide both sides by 6

x = 72/6

x = 12

Find the length of all 3 sides by plugging in the value of x in each expression:

Smallest length side = x ft = 12 ft

Middle length side = (2x + 4) ft = (2(12) + 4) = 24 + 4 = 28 ft

Longest length side = (3x - 4) ft = (3(12) - 4) = (36 - 4) = 32 ft

Step-by-step explanation:

The * sign is a way to show multiplication so that the "x" variable isn't mistaken for you to multiply or vice versa.

-3 * -6 = 18 because a negative number times a negative number has the sum of a positive number.

Answer:

  Y = 6.5°

Step-by-step explanation:

We know that tan(x) = cot(90°-x), so we could rewrite the equation as ...

  cot(90 -(3Y+32)) = cot(Y+32)

  58 -3Y = Y +32

  26 = 4Y

  6.5 = Y

One solution is Y = 6.5°.

Answer:

A) Kaden

B)Siaem

Step-by-step explanation:

the first number or part of a ratio is the numerator, and the second is the denominator, for part A 2 is the numerator and 3 is the denominator. the 30 is also the denominator so it would go on the bottom and x would be the numerator since we didn´t know the value of it. this also applies for Part B.

Hope it helps :)

Answer:

mean is the average of the numbers (add them all up then divided by how many number there are)

mode is the number that comes out the most often

range is the largest number minus the smallest

median is the middle number when they are lined up from greatest to the least  (unless there's two)

Step-by-step explanation:

a song we learned in 5th grade XD that i still remember somehow

Answer:

This is what mean, median, and mode are-

Step-by-step explanation:

Mean is when you add all the number there are and divide by the total of numbers that you added together like this for example.

(1+2+3+4+5 = 15) THEN (15 / 5 = 3) THE MEAN IS 3.

Median is when you group the number from smallest to biggest and keep on crossing out both side of the number till you reach the middle.

(1, 2, 3, 4, 5) YOUR MEDIAN SHOULD BE 3 CAUSE IF YOU CROSS OUT 1,5 THEN 2,4 YOU WILL GET 3.

Mode are the most common number that you will see. You could have no mode or many mode too.

(1, 2, 2, 3, 4, 5) THERE IS ONLY ONE MODE HERE WHICH IS 2.

(1, 2, 3, 4, 5) THERE IS NO MODE CAUSE THERE IS NO REPEATING NUMBER.

(1, 2, 3, 4, 4, 5, 5) THERE IS TWO MODE NOW WHICH ARE 4 AND 5.

Ok What is the Question?

Answer:

The vertex of this parabola is [tex](-2,-11)[/tex]

Step-by-step explanation:

One way of finding the x-coordinate of the vertex of a parabola is by using the equation [tex]-\frac{b}{2a}[/tex]

From the function [tex]f(x)=x^2+4x-7[/tex], we can see that

[tex]a=1\\b=4\\c=-7[/tex]

This means that

[tex]-\frac{b}{2a}=-\frac{4}{2(1)} =-2[/tex]

So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.

[tex]f(x)=x^2+4x-7\\\\f(-2)=(-2)^2+4(-2)-7\\\\f(-2)= 4-8-7\\\\f(-2)=-11[/tex]

Thus, the vertex of this parabola is [tex](-2,-11)[/tex]

slope = 2

Step-by-step explanation:

-8 - -6 / -9 - -8 = 2

Answer:

[tex]\frac{2}{1}[/tex] which is just 2

Step-by-step explanation:

slope = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

So plug the numbers in, now it should look like [tex]\frac{-6 - (-8)}{-8 - (-9)}[/tex]

-6 - (-8) = 2

-8 - (-9) = 1

Answer:

A. 34in

Step-by-step explanation:

If James completely covered a square poster board using 68.2 inches with an exponent of 2, the the total perimeter of the square will be;

P = 2(68.2) = 136.4in

Since the perimeter of a square is expressed as:

P = 4L

136.4 = 4L

L = 136.4/4

L = 34.1in

Hence the measurement of one side of the square poster is closest to 34in
