Answer:

c = [tex]\frac{27}{40}[/tex]

Step-by-step explanation:

To eliminate the fractions, multiply all terms by the lowest common multiple of 8 and 5

The lowest common multiple of 8 and 5 is 40

5 + 40c = 32 ( subtract 5 from both sides )

40c = 27 ( divide both sides by 40 )

c = [tex]\frac{27}{40}[/tex]

Answer:

(3x^2-5x-5)/(x^2+x) <--- answer  

Step-by-step explanation:

3x/(x+1) - 5/x = (3x^2 - 5(x+1) )/[ x(x+1) ]  

= (3x^2 - 5x - 5)/(x^2 + x)

The difference between the rational expressions 3x+1/x and 5/x is 3x - 4/x.

The difference between these two rational expressions will be obtained by subtracting the second expression from the first. To do this, we first need to simplify the expressions wherever possible. The first expression, 3x + 1/x, remains as it is. The second expression, 5/x, is a simple fraction and can't be simplified any further either.

Subtracting the second from the first, you get (3x + 1/x) - (5/x) which simplifies to 3x - 4/x. The difference between these two rational expressions is hence 3x - 4/x.

Step-by-step explanation:

Orange to Apple juice = 3:1.

Work out the 'multiplier':

3 + 1 = 4.

3 parts are orange so we need 3 * the multiplier = 3*4 = 12  litres.

Part A: Scatter plot with best-fit line attached. You'll find the line to have equation (approximately)

Answer:

The values of x are x= 2i and x= -2i

Step-by-step explanation:

We need to solve the equation:

2x^2 + 8 =0

Taking 2 common

2(x^2 +4) =0

Dividing both sides by 2

x^2+4 =0

Adding -4 on both sides

x^2 +4 -4 = 0-4

x^2 = -4

Taking square root on both sides we get

√x^2 = √-4

we know √4 = 2 and √-1 = i so answer is:

x = ± 2i

The values of x are x= 2i and x= -2i

The graph is shown in figure attached.

To solve 2x² + 8 = 0 by graphing, one plots the corresponding quadratic function f(x) = 2x² - 8, which is a parabola that opens upwards. The equation has no real solutions as the function does not cross the x-axis, indicating that the original quadratic equation has no real roots.

To solve the quadratic equation 2x² + 8 = 0 by graphing the related function, we first need to rewrite the equation in the standard form of a quadratic function, which is f(x) = ax² + bx + c. In this case, the equation becomes f(x) = 2x² + 0x - 8.

The roots of the equation are the values of x where the function crosses the x-axis. To find these, we set the function equal to zero and solve for x. Subtracting 8 from both sides gives us 2x² = -8. Dividing by 2, we get x² = -4. Taking the square root of both sides, we see that x could be either positive or negative square root of -4, which does not have a real solution since you can't have a real number whose square is negative. Therefore, the graph of the function will not cross the x-axis and there are no real roots to this equation.

If we were to graph this function, we would plot the quadratic curve and notice that it is a parabola opening upwards because the coefficient of x² is positive. However, as we have established there are no real solutions, this would be confirmed by the fact that the vertex of the parabola is above the x-axis.

Find the length of a side of a square with an area of 169 in^2.

Answer:

D. 13 in

Step-by-step explanation:

A square has sides of equal length.

A = L^2 where:  A = area  and  L = side

L^2 = 169

L=√169

L=13 in^2.    

The length of a side of a square with an area of 169 in2 is calculated by taking the square root of the area, which is 13 inches. The correct answer is D. 13 in.

The student is asking to find the length of a side of a square given that the area of the square is 169 square inches. The formula to calculate the area of a square is side length squared, which can be written as:

Area = side × side

To find the side length, we need to take the square root of the area:

Side = √169

Upon calculation, the side length is:

Side = 13 {in}

Therefore, the correct answer is D. 13 in.

Answer:

[tex] \frac{4}{5} \div \frac{2}{3} = n[/tex]

[tex] \frac{4}{5} = n \times \frac{2}{3} [/tex]

[tex] \frac{3}{2} \div \frac{4}{5} = n [/tex]

[tex] \frac{4}{5} = n \times \frac{2}{3} [/tex]

[tex] \frac{2}{3} \times n = \frac{4}{5} [/tex]

x/2 + 10 = 35 - 2x

x/2 + 2x = 35 - 10

5x/2 = 25

5x = 25.2

5x = 50

x = 50/5

x = 10

The number is 10

Let's take it step by step to find the number for the given situation:
Step 1: Define the variable.
Let's denote the number we are trying to find as \( x \).
Step 2: Set up the equation based on the given information.
The problem statement says "Half a number increased by 10 is equal to 35 less than twice the number." This gives us the equation:
\[ \frac{1}{2}x + 10 = 2x - 35 \]
Step 3: Solve the equation.
Now we'll solve for \( x \). To do this, we need to get all terms involving \( x \) on one side and the constant terms on the other. Start by subtracting \( \frac{1}{2}x \) from both sides to get rid of the \( x \) term on the left-hand side:
\[ 10 = \frac{3}{2}x - 35 \]
Now, add 35 to both sides to isolate the \( x \)-related term on the right-hand side:
\[ 10 + 35 = \frac{3}{2}x \]
\[ 45 = \frac{3}{2}x \]
Next, to solve for \( x \), multiply both sides by \( \frac{2}{3} \) to cancel out the fraction:
\[ \frac{2}{3} \cdot 45 = x \]
\[ x = 30 \]
Step 4: Verify the solution.
Plugging the value of \( x \) back into the original equation to check:
\[ \frac{1}{2} \cdot 30 + 10 = 2 \cdot 30 - 35 \]
\[ 15 + 10 = 60 - 35 \]
\[ 25 = 25 \]
The equation is true, confirming that the solution \( x = 30 \) is correct.
Therefore, the number we were trying to find is 30.

Final answer:

Linda sent 8 text messages, Jim sent 15 messages, and Dale sent 60 messages during the weekend.

Explanation:

The question asks to solve a word problem to find out how many text messages Linda, Dale, and Jim sent over the weekend.

Let's denote the number of messages Linda sent as L, Jim as J, and Dale as D.

The problem states that Jim sent 7 more messages than Linda, so J = L + 7.

Dale sent 4 times as many messages as Jim, so D = 4J.

Together they sent 83 messages, which gives us the equation L + J + D = 83.

Substituting the expressions for J and D in terms of L into the equation, we get L + (L + 7) + 4(L + 7) = 83.

This simplifies to 6L + 35 = 83. Solving for L gives us L = 8.

This means Linda sent 8 messages, Jim sent 15 messages (8 + 7), and Dale sent 60 messages (4 times 15).

Answer:

4

Step-by-step explanation:

Let's call the width W and the length L.

We know the width is 3 less than the length, so:

W = L - 3

And we know the area is 28, so:

28 = WL

If we solve for L in the first equation:

L = W + 3

And substitute into the second equation:

28 = W (W + 3)

28 = W² + 3W

0 = W² + 3W - 28

0 = (W + 7) (W - 4)

W = -7, 4

Since W can't be negative, W = 4 units.

The width, in units, of the rectangle, if the area of the rectangle is 28 units, is  4 units.

The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Given:

The width of a rectangle is 3 units less than the length. The area of the rectangle is 28 units,

Write the equation as shown below,

b = l - 3   (Here, l is the length and b is the width)

l × b = 28

Solve the above equations,

l = 7 units and b = 7 - 3 = 4 units

Therefore, the width, in units, of the rectangle, if the area of the rectangle is 28 units, is  4 units.
