Answer fast? What?

x + 2y = 17...Equation A

8x + 3y = 45...Equation B

Solve A for x.

x = 17 - 2y

Plug this into B to solve for y.

8(17 - 2y) + 3y = 45

136 - 16y + 3y = 45

136 - 13y = 45

-13y = 45 - 136

-13y = -91

y = -91/-13

y = 91/13

y = 7

To find y, plug x = 7 into either equation to find x.

I will use Equation A.

x + 2y = 17

x + 2(7) = 17

x + 14 = 17

x = 17 - 14

x = 3

Answer: x = 3, y = 7

The  solution to the system of equations is (x = 3) and  (y = 7).

To find the values of x and y that satisfy the given system of equations:

1.  (x + 2y = 17)

2. (8x + 3y = 45)

We can use either the substitution method or the elimination method. Let's use the elimination method to solve this system

Step 1: Multiply both sides of the first equation by 3 to make the coefficients of y in both equations the same:

(3x + 6y = 51)

Step 2: Now, subtract the modified first equation (3x + 6y = 51) from the second equation (8x + 3y = 45):

(8x + 3y) - (3x + 6y) = 45 - 51)

Simplify:

(8x + 3y - 3x - 6y = -6)

Step 3: Combine like terms:

(5x - 3y = -6)

Step 4: Now, we have two equations:

1. (x + 2y = 17)

2. (5x - 3y = -6)

Step 5: Now, you can either use the substitution method or the elimination method again to find the values of x and y. Let's use the elimination method again to eliminate y: Multiply the first equation by 3 and the second equation by 2 to make the coefficients of y the same:

1. (3(x + 2y) = 3 times 17)  =>  (3x + 6y = 51)

2. (2(5x - 3y) = 2 times -6)  =>  (10x - 6y = -12)

Step 6: Now, add the modified first equation (3x + 6y = 51) to the modified second equation (10x - 6y = -12):  (3x + 6y + 10x - 6y = 51 - 12)

Simplify: (13x = 39)

Step 7: Divide both sides by 13 to solve for x:

  (x = frac{39}{13})

    (x = 3)

Step 8: Now that we have the value of x, we can find the value of y by substituting it back into either of the original equations. Let's use the first equation:

(x + 2y = 17)

(3 + 2y = 17)

Step 9: Solve for y:

(2y = 17 - 3)

(2y = 14)

(y = frac {14}{2})

(y = 7)

Answer:

15

Step-by-step explanation:

Since 30 and 45 are relatively small numbers, it's not a big deal to list every single one of their common factors.

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

Factors of 45: 1, 3, 5, 9, 15, 45

Now that we have a list, it's easy to see which number is the highest common factor, which is, of course, 15.

Answer:

HCF of 30 and 45 is 15.

Step-by-step explanation:

Factors of 30 : 1, 2, 3, 5, 6, 10, 15, 30.

Factors of 45 : 1, 3, 5, 9, 15, 45.

Answer: the representative sample contained more adults than children

Step-by-step explanation:

The options are:

a. The representative sample contained all 200 tourists.

b. The representative sample contained more adults than children.

c. The representative sample contained more children than adults.

d. The representative sample contained an equal number of adults and children.

Number of adults = 150

Number of children = 50

Total = 150 + 50 = 200

Probability of choosing an adult = 150/200 = 0.75

Probability of choosing a child = 50/200 = 0.25

The above shows that the representative sample contained more adults than children. This can be seen in the explanation above as number of adults is thrice that of children.

Answer:

A group of tourists is determining the order in which to visit national landmarks in Washington, DC. The group contains 200 people. Of those people, 150 are adults, and 50 are children. A random sample of tourists in the group is chosen. Surveying the random sample produced a representative sample of the population. Which was most likely true of the representative sample?

the representative sample contained more adults than children

Step-by-step explanation:

The options are:

a. The representative sample contained all 200 tourists.

b. The representative sample contained more adults than children.

c. The representative sample contained more children than adults.

d. The representative sample contained an equal number of adults and children.

Number of adults = 150

Number of children = 50

Total = 150 + 50 = 200

Probability of choosing an adult = 150/200 = 0.75

Probability of choosing a child = 50/200 = 0.25

The above shows that the representative sample contained more adults than children. This can be seen in the explanation above as number of adults is thrice that of children.

Step-by-step explanation:

Answer:

The width of the door is 36 inches

Step-by-step explanation:

The given parameters are;

The given area of the door = 3024 in.²

The length of the door = 48 + The width of the door

Let W represent the width of the door

Therefore, we have;

The length of the door = 48 + W

The area of the door = The length of the door × The width of the door

∴ By substitution, the area of the door = 3024 = W × (48 + W)

3024 = W × (48 + W) = 48·W + W²

48·W + W² = 3024

∴ 48·W + W² - 3024 = 0

Rearranging, we get;

W² + 48·W - 3024 = 0

By trial and error, we have;

(W + 84)×(W - 36) = 0

Therefore, given that the width of the door is a natural number, we have;

The width of the door, W = 36 inches
