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.

Common Factors : 1, 3, 5, 15

Step-by-step explanation:

-23 = 13w + 2w + 22

Combine like terms (add 13w and 2w and subtract 22 from both sides)

-45 = 15w

Divide both sides by 15

w = -3

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:

x = 23

y = 7

z = 11

Step-by-step explanation:

Since ∆PRS ≅ ∆CFH, therefore,

m<R = m<F

13y - 1 = 90° (substitution)

Add 1 to both sides

13y - 1 + 1 = 90 + 1

13y = 91

Divide both sides by 13

13y/13 = 91/13

y = 7

Since ∆PRS ≅ ∆CFH, therefore,

PS = CH

2x - 7 = 39 (substitution)

Add 7 to both sides

2x - 7 + 7 = 39 + 7

2x = 46

Divide both sides by 2

2x/2 = 46/2

x = 23

Since ∆PRS ≅ ∆CFH, therefore,

m<S = m<H

Find m<S

m<S = 180 - (m<P + m<R) (sum of ∆)

m<S = 180 - (28 + (13y - 1)) (substitution)

Plug in the value of y

m<S = 180 - (28 + (13)(7) - 1))

m<S = 180 - (28 + 91 - 1)

m<S = 180 - 118

m<S = 62°

Therefore, since m<S = m<H,

62° = 6z - 4 (substitution)

Add 4 to both sides

62 + 4 = 6z - 4 + 4

66 = 6z

Divide both sides by 6

66/6 = 6z/6

11 = z

The values of x, y, and z are;

x = 23

x = 23y = 7

x = 23y = 7z = 11

We are told that triangle PRS is congruent to triangle CFH.

Since both triangles are congruent, by inspection we can see that;

m<R = m<F

m<F is a right angle = 90°. Thus;

13y - 1 = 90

13y = 90 + 1

13y = 91

y = 91/13

y = 7

Also by inspection;

PS = CH

2x - 7 = 39

2x = 39 + 7

2x = 46

x = 46/2

x = 23

Since m<R is 90°, then;

m<S = 180 - (90 + 28)

m<S = 62°

By inspection;

m<S = m<H

Thus;

6z - 4 = 62

6z = 66

z = 66/6

z = 11
