Answer:

3 child tickets and 2 adult tickets

Step-by-step explanation:

5t = 26

2c + 10a = 26

c = 3  a = 2

(2 * 3) + (10 * 2) = 26

6 + 20 = 26

The equations are c + a = 5 and 2c + 10a = 26. Then the number of children and adults will be 2 and 3, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Mr. Frankel bought 5 tickets to a puppet show and spent $26. He bought a combination of child tickets for $2 and adult tickets for $10 each.

Let 'c' be the number of children and 'a' be the number of adults. Then we have

a + c = 5                     ...1

2c + 10a = 26            ...2

From equations 1 and 2, then we have

2(5 - a) + 10a = 26

10 - 2a + 10a = 26

8a = 16

a = 2

Then the value of the variable 'c' is calculated as,

2 + c = 5

c = 3

The equations are c + a = 5 and 2c + 10a = 26. Then the number of children and adults will be 2 and 3, respectively.

Answer:

It is 1/2

Step-by-step explanation:

the rise is 2

the run is 4

2 over four simplifies to one half

Answer:

it should be D thx

Step-by-step explanation:

Step-by-step explanation:

16. d-4 = -7

or, d = -7+4

or, d = -3

therefore, d = -3.

17. c-34 = 20

or, c = 20+34

or, c = 54

therefore, c = 54

18. a-4 = -18

or, a = -18 + 4

or, a = -14

therefore, a = -14

19. r-3 = 8

or, r = 8+3

or, r = 11

therefore, r = 11

20. z-100 = 100

or, z = 100+100

or, z = 200

therefore, z = 100

21. 5 = d - 1

or, 5+1 = d

or, 6 = d

or, d = 6

therefore, d = 6

Answer:

since angle a and b are vertical angles

therefore we can say that,

i) <A=<B

or,20x+10=30x-10

or,10+10=30x-20x

or,20=10x

.°. x=10.

Answer:

9

Step-by-step explanation:

Answer:

1. y² = 169

taking a square root of both sides

y = √169

we know that 13 * 13 = 169

since when squaring a number, the signs on the numbers do not matter

(i.e - 2* 2 = 4 and (-2)*(-2) = 4)

So (-13) * (-13) = 169 as well

Hence we can say that √169 = ±13      OR      √169 = +13   and   -13

2. Volume of a cube-shaped crate = side*side*side

Volume = side³

(We are given that volume = 27)

27 = side³

side = ∛27

Since 3*3*3 = 27     and (-3)*(-3)*(-3) = 27

So, we can say that ∛27  = ± 3

BUT

the side of a crate cannot be negative, so the side will NOT be -3 and hence,

side = 3

3. b³ = 1000

we know that 10*10*10 = 1000    and     (-10)*(-10)*(-10) = 1000

So, ∛1000 =  ∛(10*10*10)= ±10

4. Area of a square(Patio)  = Side²

Area = Side²

196 = Side² (Since we are given the area of the patio)

Side = √196 = √(14*14) or √(-14*-14)

Hence,

Side = + 14 or -14

but the side of a patio cannot be negative

Side = +14 ft

It will cost $412.50 for equipment for all stations.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Dan orders supplies for the science lab. Each of the 30 stations in the chemistry lab needs 5 feet of rubber tubing. If rubber tubing sells for $8.25 per yard.

The cost will be calculated as below,

3 feet = 1 yard

5 x 30 = 150 feet

8.25 per yard = cost

150/ 3 = 50 yards (total tubing needed)

50 x 8.25 = $ 412.50

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Notice:  The literal factors are all the combinations of a and b where the sum of the exponents is 4:  a4,  a3b,  a2b2,  ab3,  b4.

The degree of each term is 4.

The first term is actually a4b0, which is a4 · 1.

Thus to "expand" (a + b)5, we would anticipate the following terms, in which the sum of all the exponents is 5:

(a + b)5 =  ? a5 +  ? a4b +  ? a3b2 +  ? a2b3 +  ? ab4 +  ? b5

The question is, What are the coefficients?

They are called the binomial coefficients.  In the expansion of

(a + b)4, the binomial coefficients are

1  4  6  4  1

The coefficients in the expansion are 1, 4, 6, 4, 1.

The sum of exponents of x and y is always n. The binomial coefficients which are equidistant from the beginning and from the ending are equal i.e. [tex]^nC_0[/tex]= [tex]^nC_n[/tex], [tex]^nC_1[/tex]= [tex]^nC_{n-1}[/tex], [tex]^nC_2[/tex]= [tex]^nC_{n-2}[/tex] ,….. etc.

The expansion of [tex](x+ y)^4[/tex]

= [tex]x^4[/tex] + 4x³y + 6x²y² + 4xy³ + [tex]y^4[/tex]

So, the highest degree is 4.

and, The literal factors are all the combinations are  [tex]x^4[/tex], 4x³y, 6x²y², 4xy³,[tex]y^4[/tex]

Hence, the coefficients in the expansion are 1, 4, 6, 4, 1.

The direct variation equation is y = 6x

Step-by-step explanation:

The direct variation equation is y = kx, where

To find the value of k, use the initial values of x and y

∵ y = 5, y = 30

∵ y = k x

→ Substitute the values of x and y to find k

∵ x = 5 and y = 30

∴ 30 = k (5)

∴ 30 = 5k

→ Divide both sides by 5

∴ [tex]\frac{30}{5}=\frac{5k}{5}[/tex]

∴ 6 = k

→ Substitute it in the form of the equation

∴ y = 6x

The direct variation equation is y = 6x

Answer:

Mitchell's dog is 3 years old

Step-by-step explanation:

9 x 1/3 = 3

9 + 3 = 12

To solve this I just thought of the multiples of three under 12 that if added to 3 are equal to 12 to find Katie's cat age. The multiples of three under 12 are 3, 6 and 9. It couldn't be 3 and 6+3=9 so it had to be 9. So if Katie's cat is 9, you just multiply 9 by 1/3 or divide it by 3 to find Mitchell's dog age.

The required number of employees being laid off is 90.

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

Given that,

The number of employees laid off last year was 75.

The percentage increase in laid off  for present year is 20%.

The number of employees laid off can be calculated as follows,

75 + 20% of 75

= 75 + 20/100 × 75

= 75 + 15

= 90

Hence, the number of employees laid off in the present year is 90.
