Answer:

17/56

7/8 - 4/7 = 17/56

Answer:

17/56

Step-by-step explanation:

Multiply 7 by 7 and get 49

Then Multiply 4 by 8 and get 32

Then we Multiply the Denominators 8×7= 56

that's how u get /56

now u look at the numerators 49/56 32/56

49-32= 17

thats how u Get 17/56

Answer:

x = 1, x = -19

Step-by-step explanation:

1) factorise

(x−1)(x+19)=0

2) equal to 0

x−1=0 or x+19=0

x=1 or x=−19

Answer:

[tex]x = 1[/tex]

[tex]x = 19[/tex]

Step-by-step explanation:

Set up equation

[tex] {x}^{2} + 18x - 19 = 0[/tex]

Add 19 on both sides

[tex] {x}^{2} + 18x = 19[/tex]

Divide 18 by 2 and sqr it.

[tex]( \frac{18}{2}) {}^{2} [/tex]

[tex] {9}^{2} = 81[/tex]

Add 81 on both sides

[tex] {x}^{2} + 18x + 81 = 100[/tex]

Using the AC method, isolate the left side into a binomial.

[tex](x + a)(x + b)[/tex]

that a and b can be added to equal 18 and be multiplied to equal 81.

Only number that does that is 9. 9+9=18, 9×9=81

[tex](x + 9)(x + 9)[/tex]

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

Set up equation

[tex](x + 9) {}^{2} = 100[/tex]

Take sqr root of both sides

[tex]x + 9 = 10[/tex]

Since sqr root of a positve number can be negative, set up this equation also

[tex]x - 9 = 10[/tex]

[tex]x = 1[/tex]

OR

[tex]x = 19[/tex]

Answer:

trees

Step-by-step explanation:

Trees are renewable resources. Trees can be planted, grown up, and harvested for timber. Forests are a different thing, however. A forest is a mature ecosystem.

Trees are renewable resource.

Option D is correct.

A renewable resource is one that can replace itself spontaneously over time. As a result, despite human usage, it is sustainable.

Renewable resources are particularly important because of their potential to replace non-renewable, or finite, resources in energy production. Furthermore, renewable resources can provide cleaner energy solutions than nonrenewable resources such as coal and fossil fuels.

Coal, gemstones, and metals are considered as non-renewable resources since they can be exhausted and are not available for lengthy periods of time. They are used as time goes on.

Thus, Trees are Renewable resources.

Answer:

226 1/8

Step-by-step explanation:

Substitute the measurements of the container into the formula.

The amount of cardboard Rajek can fit in the container at one time is  cubic feet.

The total surface area of the container is 9L + 9W + 50 1/4

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

To find the total amount of cardboard that can fit in the container at one time, we need to find the surface area of the container.

The container has a rectangular base with an area of 50 1/4 square feet.

Let's assume the length of the base is L and the width is W.

We know that:

L x W = 50 1/4

We also know that the height of the container is 4(1/2) feet, which is equivalent to 9/2 feet.

The container has two identical sides, which are rectangles with a length of L and a height of 9/2 feet.

The surface area of one side is:

L x (9/2) = (9/2)L

The container also has two identical ends, which are rectangles with a width of W and a height of 9/2 feet.

The surface area of one end is:

W x (9/2) = (9/2)W

Finally, the container has a top, which is a rectangle with a length of L and a width of W.

The surface area of the top is:

L x W

To find the total surface area of the container, we add up the surface area of each of these parts:

Total surface area = 2(L x (9/2)) + 2(W x (9/2)) + (L x W)

Simplifying this expression, we get:

Total surface area = 9L + 9W + LW

We know that L x W = 50 1/4, so we can substitute this into the equation:

Thus,

The total surface area of the container is 9L + 9W + 50 1/4

Answer:

[tex]\boxed {\boxed {\sf 3 \ pounds \ of \$4 \ candy}}[/tex]

[tex]\boxed {\boxed {\sf 2.5 \ pounds \ of \$3.50 \ candy}}[/tex]

Step-by-step explanation:

Let's create a system of equation. First, define the variables. One type of candy is x and the other is y.

Now, create 2 equations, one for the weight and one for the price.

[tex]x+y=5.5[/tex]

[tex]4x+3.5y=20.75[/tex]

The first equation represents the mixture of both types of candy that weighs 5.5 pounds. The second represents the prices of the candy and the mixture.

Next. solve for the variables using substitution. Isolate a variable in the first equation. Let's isolate y by subtracting x.

[tex]x-x+y=5.5-x\\y= 5.5-x[/tex]

Now, we know what y is equal to, so we can substitute it into the second equation.

[tex]4x+ 3.5 (5.5-x)= 20.75[/tex]

Distribute the 3.5. Multiply each term by 3.5

[tex]4x+(3.5*5.5)+(3.5*-x)[/tex]

[tex]4x+19.25-3.5x= 20.75[/tex]

Combine like terms on the right side.

[tex]0.5x+19.25=20.75[/tex]

Subtract 19.25 from both sides of the equation to isolate the variable.

[tex]0.5x+19.25-19.25=20.75-19.25[/tex]

[tex]0.5x= 1.5[/tex]

Divide both sides by 0.5.

[tex]\frac {0.5x}{0.5}= \frac{1.5}{0.5}\\x=3[/tex]

Now we can substitute x back into the first equation and solve for y.

[tex]x+y=5.5\\3+y=5.5[/tex]

Subtract 3 from both sides to isolate the variable.

[tex]3-3+y=5.5-3\\y=2.5[/tex]

There was 3 pounds of the $4 candy and 2.5 pounds of the $3.50 candy.

Answer:

x = 8

Step-by-step explanation:

Apply the exterior angle theorem.

Thus:

45 + 6x + 7 = 13x - 4

Add like terms

52 + 6x = 13x - 4

52 + 6x - 13x = 13x - 4 - 13x

52 - 7x = -4

52 - 7x - 52 = -4 - 52

-7x = -56

-7x/-7 = -56/-7

x = 8

Step-by-step explanation:

Part A: Let see what number we can multiply by 3 to get 13.5

[tex]3x = 13.5[/tex]

[tex]x = 4.5[/tex]

so our answer is 4.5

Part B : Set up the proportion

3 and 13.5 correspond with each other and the question mark side corresponds with the 9 cm side.

let x = the side we are trying to find

[tex] \frac{3}{x} = \frac{13.5}{9} [/tex]

Cross multiply

[tex]27 = 13.5x[/tex]

[tex]x = 2[/tex]

Answer:

1.02n

Step-by-step explanation:

A simplified version of this expression would be the following

1.02n

This is basically adding the n variables together. We do this by adding a 1 to the number being multiplied to n. This would basically add the 2% on top of what the original pay per hour is. We can prove that these two expressions are the same by substituting n for 10 in both expressions and solving them.

1.02n

1.02 * 10 = 10.2

n + 0.02n

10 + 0.02*10

10 + 0.2 = 10.2
