Step-by-step explanation:

Step 1: Convert into improper fractions

Step 2: Find  least common denominator and find equivalent fractions

Step 3 : Do the required operation

[tex]3\frac{1}{2}+2\frac{1}{4}-1\frac{1}{2}=\frac{7}{2}+\frac{9}{4}-\frac{3}{2}\\[/tex]

Least common denominator of 2 , 4 = 4

Answer:

x = 10

Step-by-step explanation:

To isolate the variable (x) you would first write out x - 3 = 7. Now to make x on its own we have to get rid of the -3 so to do that we would add the reciprocal of -3 (or the opposite) which is +3. x - 3 + 3 = 7 + 3 or x = 10.

The value of the expression is 3a² + 2b² is 69.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

Expression: 3a² + 2b²

Not, put the value of a= -3 and b=6 we get

= 3a² + 2b²

= 3(-3)² + 2(4)²

= 3 x 9 + 2 x 16

= 37 + 32

That is your triangle.

Now, since its a right triangle, we can use the Pythagorean theorem to solve for x.

The equation for the Pythagorean theorem is this: [tex]A^{2} + B^{2} = C^{2}[/tex]

So we plug in the values.

[tex](x^{2} ) + (x-9)^{2} = (x + 9)^{2}[/tex]

We solve for x.

[tex]x^{2} + x^{2} -18x + 81 = x^{2} + 18x + 81[/tex]

Get everything to the left side of the equation. (x^2 + x^2 = 2x^2, - x^2 = x^2;

-18x - 18x = -36x;    81 - 81 = 0)

[tex]x^{2} -36x = 0[/tex]

Add 36x to both sides, then divide by x.

[tex]x^{2} = 36x\\\\x = 36[/tex]

Answer:

y = 32

Step-by-step explanation:

[tex]\frac{1}{2} y + 22 = 38[/tex]

Subtract 22 from both sides to isolate the y variable.

[tex]\frac{1}{2} y = 16[/tex]

Divide both sides by [tex]\frac{1}{2}[/tex], which is the same as multiplying by 2.

y = 32

1/2y + 22 = 38

         -22    -22

1/2y = 16

x2      x2   ---> This is because if 1/2y = 26, that means y times 1/2 is 26, but we                  want to know what y times 1 is because y times 1 is equal to y so we multiply by 2 because 1/2 times 2 equals 1.

y = 32

Answer: $3.50

Step-by-step explanation:

Let the cost of domestic shipping be x.

Since the cost of international shipping is $2.50 greater than the cost of domestic shipping. This will be:

= x + 2.50

Since we are further told that three of the cards will be shipped domestically, and two will be shipped internationally and that $22.50 will be spent on shipping, this will be express in an equation as:

3x + 2(x + 2.50) = 22.50

3x + 2x + 5.00 = 22.50

5x = 22.50 - 5.00

5x = 17.50

x = 17.50/5

x = $3.50

The cost if domestic shipping is $3.50

x = 2.4/20= 0.12

Step-by-step explanation:

Multiply both sides by 4 to eliminate the fraction 1/4:

1      20

--- = ------

x      2.4

Next, we cross-multiply.  This eliminates the fractions:

20x = 2.4

Dividing both sides by 20 results in an equation for x:  x = 2.4/20= 0.12

Answer:

30

Step-by-step explanation:

create a function where x is the money you insert in cents and y is the amount of gumballs you get.

y = x - 5 (meaning you get five less gumballs than the amount of cents you insert)

Therefore, when x = 35:

y = 35 - 5 = 30.

You will get 30 gumballs.

X=x−4

Step-by-step explanation:

2(x−3)+X=5x−2(x+5)

Use the distributive property to multiply 2 by x−3.

2x−6+X=5x−2(x+5)

Use the distributive property to multiply −2 by x+5.

2x−6+X=5x−2x−10

Combine 5x and −2x to get 3x.

2x−6+X=3x−10

Subtract 2x from both sides.

−6+X=3x−10−2x

Combine 3x and −2x to get x.

−6+X=x−10

Add 6 to both sides.

X=x−10+6

Add −10 and 6 to get −4.

X=x−4

Answer:

(1) [tex](x,y) = (-2,-4)[/tex]

(2) [tex]y = 4x -26[/tex]

(3) [tex]x = 1[/tex]

Step-by-step explanation:

(1):

[tex]2x - y = 0[/tex]

[tex]x + 3y = -14[/tex]

Required: Solve for x and y

Make x the subject in [tex]x + 3y = -14[/tex]

[tex]x = -3y - 14[/tex]

Substitute -3y - 14 for x in the first equation

[tex]2x - y = 0[/tex]

[tex]2(-3y-14) - y = 0[/tex]

Open bracket

[tex]-6y - 28 - y = 0[/tex]

Collect Like Terms

[tex]- y-6y = 28[/tex]

[tex]-7y = 28[/tex]

Divide both sides by -7

[tex]y = -4[/tex]

Substitute -4 for y in [tex]2x - y = 0[/tex]

[tex]2x - (-4) = 0[/tex]

[tex]2x + 4 = 0[/tex]

Collect Like Terms

[tex]2x = -4[/tex]

Divide by 2

[tex]x = -2[/tex]

Hence, the solution is:

[tex](x,y) = (-2,-4)[/tex]

(2):

[tex](x_1,y_1) = (7,2)[/tex] -- points

[tex]m = 4[/tex] --- slope

Required: Determine the line equation

This is calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = 4(x - 7) + 2[/tex]

Open bracket

[tex]y = 4x - 28 + 2[/tex]

[tex]y = 4x -26[/tex]

(3)

[tex]4 - 5x + 3 = 4x - 2[/tex]

Required: Solve for x

Collect Like Terms

[tex]- 5x -4x = - 2-3-4[/tex]

[tex]-9x = -9[/tex]

Divide both sides by -9

[tex]x = 1[/tex]

You can get a pair of shoes that normally cost $84 for only $72.

We need to find the discount percentage. So, it can be calculated as follows :

So, the required percentage is 14.28%.

Answer:

45 mph

Step-by-step explanation:

Using the equation d = rt, we can rearrange the equation to be t = d/r

Since the amount of time was the same, we can set d/r equal to each other for both speeds.

Let x represent the average speed.

[tex]\frac{d}{r}[/tex] = [tex]\frac{d}{r}[/tex]

[tex]\frac{180}{x}[/tex] = [tex]\frac{200}{x+5}[/tex]

Cross multiply and solve for x:

200x = 180x + 900

20x = 900

x = 45

So, the average speed was 45 mph

The total price for the gallons of paint will be 35.75p

The total price for the rollers will be 6r

Step-by-step explanation:

Slope = change in Y / change in x:

Slope = (5- 5) / (-1 - -9)

Slope = 0/8

Because the change in Y = 0, the slope = 0

Slope = 0

Answer:

0

Step-by-step explanation:

(-9,5) and (-1,5)

To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(5 - 5) / (-1 - 9)

Simplify the parentheses.

= (0 ) / (-10)

Simplify the fraction.

0/-10

= 0

This is your slope.

This is also a horizontal line, which will have a slope of 0.
