Therefor, the answer is 35 + 9m.

Answer:

first we fisson in three regtangles. and we gain 6 cm to 3cm regtangles. they have the same width and length.

and we find their area. we multiplay 6cm and 3cm. the result is 18 cm square. and they have the same area.

lastly we find the value of the picture by find the sum of three regtangels.18cm square+18cm square+18cm square=

54cm square. fainally the answer is 54cm square.

Answer:

5 days

Step-by-step explanation:

Given

Damian

[tex]Base\ Items = 5[/tex]

[tex]Rate = 3[/tex] daily

Andrea

[tex]Rate =4[/tex] daily

Required [Missing from the question]

How long will they get the same number of items

Represent the number of items with x and the days with y.

So:

For Damian

[tex]y = Base\ Items + Rate * x[/tex]

[tex]y = 5 + 3 * x[/tex]

[tex]y = 5 + 3 x[/tex]

For Andrea

[tex]y = Rate * x[/tex]

[tex]y = 4* x[/tex]

[tex]y = 4x[/tex]

Equate both expressions.

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

Collect like terms

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

[tex]x = 5[/tex]

Hence, they will have equal amount of items after 5 days

Answer:

Let 3x and 2x are divided into 250.

Step-by-step explanation:

3x + 2x = 250

⇒ 5x = 250

⇒ x =  = 50

∴ 3x = 3 × 50 = 150 and

2x = 2 × 50 = 100

Thus, the required numbers are 150 and 100.

The value of x in the hexagon is 17.

A hexagon is a polygon with six sides. The sum of angles in a hexagon is 720 degrees.

Therefore, x can be found in the hexagon as follows:

we have to sum the whole angles to get x.

110 + 8x - 1 + 5x + 36 + 116 7x + 19 + 6x - 2 + 110 = 720

combine like terms

110 + 116 - 2 + 36 - 1 + 19 + 8x + 5x + 7x + 6x  = 720

278 + 26x = 720

subtract 278 from both sides of the equation

278 + 26x = 720

278 - 278 + 26x = 720 - 278

26x = 442

divide both sides by 26

x = 442 / 26

x = 17

Answer:

A

Step-by-step explanation:

A is the answer, as you can see for every rise in 1 unit of x, there is an equivalent rise of 1 unit of y.

Answer:

-79.78 (really stinking cold)

Step-by-step explanation:

Solving the equation will go like this:

5/9(F - 32) = -62.1

multiply both sides by 9 to get rid of the fraction

5 (F - 32) = -558.9

divide both sides by 5

F - 32 = -111.78

add 32 to both sides

F = -79.78

Answer:

8x - 5  ≤ 25

Step-by-step explanation:

Given that the unknown number is x

product of 8 and a number is expressed as 8x

five substracted from the product of 8 and a number is expressed as 8x - 5

Since this expression is at most 25, the inequality sign that you are to use will be ≤ (less than or equal to) since it cannot be greater than 25. Hence the required inequality expression is 8x - 5  ≤ 25

Answer:

1.50x + 1.25y = 375

Step-by-step explanation:

x = beverages

y = candy

1.50x + 1.25y = 375

The equation that can be used to model the different numbers of beverages and candy that can be sold to meet the goal is 1.50x+1.25y=375.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of beverages sold be x, while the number of candies sold is y.

Given that the selling price of a beverage is $1.50, while the selling price of candy is $1.25. Also, the total amount that is needed to be raised is $375. Therefore, the total cost can be written as,

[tex](\$1.50 \times x)+ (\$1.25 \times y) = \$375\\\\1.50x+1.25y=375[/tex]

Hence, the equation that can be used to model the different numbers of beverages and candy that can be sold to meet the goal is 1.50x+1.25y=375.

Answer:

40.8 minutes

Step-by-step explanation:

Element X decays radioactively with a half life of 8 minutes. If there are 480 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 14 grams?

The formula to find how long it would take which is the time elapsed is given as:

t = t½ × In(Nt/No)/-In2

t = ?

t½ = 8 minutes

Nt = Amount after the time of decay = 14 grams

No = Original Amount of substances = 480 grams

t = 8 × In(14/480)/-In2

t = 40.796285388407 minutes

Approximately to the nearest tenth = 40.8 minutes

Therefore, it would take the element X, 40.8 minutes to decay to 14 grams
