PLEASE HELP!!!!
This year, the Nature Club made 3 exhibits per month for its annual fair. This year's fair has twice as many exhibits as last year's. How many exhibits were there in last year's fair?

Answer:

x=5

Step-by-step explanation:

Step 1: you want to have x alone on one side so I will subtract one x from both sides (to remove the 1 x on the right side). Now we're left with 3x=15.

Step 2: Divide both sides by 3 (to remove the 3 in front of 3x). Now we have x=5.

Answer:

30

Step-by-step explanation:

Multiples of 6 are 6,12,18,24,30.

Multiples of 10 are 10,20,30.

30 is the number they both have in common first. 30 is the LCM.

Hope this helps!

The least common multiple (LCM) of 6 and 10 is 20

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Complete question :

Roger built a model car of a station wagon he actually owns. Based on the ratio on the box, he knows that every inch in the length of his model car represents 25 inches of length in his actual station wagon. The station wagon's car manual shows that the length of the actual car is 193.75 inches.

Complete the following equation so that it can be used to find the length, m, of the model car, then find the length of the model car.

The length of the model car is _ inches

Answer:

7.75 inches

Step-by-step explanation:

Scale factor from the question is :

1 inch : 25 inches

Length of actual car = 193.75

The length of the model car = m

If :

1 = 25

m = 193.75

Using cross multiplication :

25m = 193.75

Divide both sides by 25

25m/25 = 193.75 / 25

m = 7.75 inches

Answer:

The area is 15 units squared

Answer:

6 units

Step-by-step explanation:

use imagination to separate the triangle from the square.

2*2 is 4 which is the volume of the square part

2*2/2 is the volume of the triangle which divides out to be 2

2+4=6

Answer:

yes

Step-by-step explanation:

For the lengths to form a triangle, the sum of any 2 must be greater than the third, that is

3 + 9 = 12 > 8

3 + 8 = 11 > 9

9 + 8 = 17 > 3

Thus the 3 lengths can form a triangle

Answer: El número es 4.

Step-by-step explanation:

Sea X un número.

Acá tenemos:

"Si un número se multiplica por 7"

Esto se escribe como 7*X

"... El resultado es igual al número aumentado en 24"

Esto lo podemos escribir como:

7*X = X + 24

Ahora debemos resolver esta ecuación para X.

7*X = X + 24

Primero, debemos llevar todos los términos con X al mismo lado de la ecuación, para hacer esto, podemos restar X en ambos lados:

7*X - X = (X + 24) - X

6*X = 24

Ahora debemos dividir ambos lados por 6.

6*X/6 = 24/6

X = 4

El número es 4.

Answer:

x = 24

Step-by-step explanation:

Because this shape is a parallelogram, the line segment measuring 6x must be equal to the line segment on the other side of E, which measures 144 units. 144 ÷ 6 = 24

Answer:Cross multiply and solve for x.

x/6 = 5/1.25

let the height of building be h ft

h/6 = 60/15

h = 6(60/15) = 24

the building is 24 ft high

Step-by-step explanation:

Well first let’s covert the ft to in- 5ft is 60 in and 6ft is 72 in. Then we want to set up 2 fractions based on height and shadow, so we have 60/15=x/72 (we put x because that’s what we’re trying to find). Then we do cross multiplication so now we have 15x=4320. We divide 15, so now we have 4320/15=288. So the building is 288 in tall or 24ft tall! Glad to help! :)

Answer:

8 Pigs.

Step-by-step explanation:

~ P = the number of pig

~ D = the number of ducks

p + d = 10

  4p + 2d = 36

4(10 - d) + 2d = 36

40 - 4d + 2d = 36

40 - 2d = 36

-40       = -40

    -2d = -4

    -2      -2

        d = 2 ducks

p + d = 10

p + 2 = 10

   Therefore, 8 pigs. :)) hope this helped you :))

The minimum number of sets of knives Isabella should buy will be 14 sets

Given the least number of knives needed = 439 knives

Amount currently available on ground = 230knives

The remaining amount of knives needed = 439 - 230

The remaining amount of knives needed = 209 knives

If each set on sale contains 15 knives, the number of sets Isabella will need will be:

[tex]Total \ number \ of \ set \ needed = \dfrac{209}{15}\\ Total \ number \ of \ set \ needed = 13.93[/tex]

This shows that the minimum number of sets of knives Isabella should buy will be 14 (approximately)

A

Step-by-step explanation:

Answer:

D. (4,-1)

Step-by-step explanation:

So, we have these two equations:

2x + y = 7

x - 2y = 6

Isolate x in the second equation:

x = 2y + 6

Substitute it into the first equation:

2(2y + 6) + y = 7

4y + 12 + y = 7

5y + 12 = 7

5y = -5

y = -1

Plug y back into the second equation:

x - 2(-1) = 6

x + 2 = 6

x = 4

So, the correct answer is D. (4,-1)

Answer:

#1: 146 degrees #2: 111 degrees

Step-by-step explanation:

The angles of a heptagon (a shape with 7 sides) are supposed to add up to 900 degrees, so just add up all the sides that you know and subtract it from 900 and you will have x! Do the same thing with the second one, except is is a hexagon and all the angles should add up to 720 degrees. (Don't forget to add the right angle, which is 90 degrees) So add up all the sides you know and subtract from 720 to get x.

P.S. If correct, please give Brainliest?

Answer:

N = number of sides

The sum of the interior angles of a polygon is equal to (N x 180)-360.

The first problem has 7 sides so the interior angle total = 900 degrees.

Add up all the known interior angles:

96+105+161+123+155+114+x = 900

x = 900-754 = 146 degrees

The second problem has 6 sides so the interior angle total = 720 degrees.

Add up all the known interior angles:

127+40+202+90+150+x = 720

x = 720-609 = 111 degrees

Respuesta: 0.5

Explicación paso a paso:

El posible resultado es 2:

1.) que cae un águila

2.) que un águila no cae

Cada resultado posible con igual probabilidad:

Probabilidad = resultado requerido / resultados posibles totales

P (cae un águila) = 1/2

P (el águila no cae) = 1 - 1/2 = 1/2

Por lo tanto, la probabilidad de que un águila caiga en la décima mosca es la misma que las probabilidades previas de que un águila caiga o no y es independiente. El hecho de que el águila haya caído en siete moscas consecutivas no aumenta la probabilidad de que el águila haya caído en la décima mosca.

L = 3.5                                    Given

W = 5/7  *  3.5                        Divide by 7

W = 5 * 0.5                             Combine

W = 2.5

H = 4/5 * w

H = 4/5 * 2.5

H = 4 * 0.5

H = 2

V = L * w * h

V = 3.5 * 2.5 * 2

V = 17.5
