Answer:

$0.21\ m$

Step-by-step explanation:

Let's set up a unit converter:

(Please note that 1 m = 100 cm OR 1 cm = $10^{-2}$ m)

$21\ cm(\frac{10^-2\ m}{1\ cm})$

The "cm" cancel out leaving us with:

$21*10^{-2}\ m=0.21\ m$

Identify each pair of angles as corresponding, Alternate interior, alternate exterior, or consecutive interior and solve for X

-BARSIC- [3]

Answer:

Step-by-step explanation:

19). Angles measuring 90° and (21x + 6)° are Alternate exterior angles.

Therefore, 21x + 6 = 90

2x = 90 - 6

2x = 84

x = 42

21). Angles measuring 60° and (8x - 4)° are Alternate interior angles,

8x - 4 = 60

8x = 60 + 4

x = $\frac{64}{8}$

x = 8

23). Since, angles measuring (-1 + 14x)° and (12x + 17)° are Alternate exterior angles

Therefore, (-1 + 14x) = (12x + 17)

14x - 12x = 17 + 1

2x = 18

x = 9

25). Both the angles (x + 96)° and (x + 96)° are consecutive interior angles.

Therefore, (x + 96)° + (x + 96)° = 180° [Property of consecutive interior angles]

2x + 192 = 180

2x = 180 - 192

2x = -12

x = -6

Now measure of (x + 96)° = -6 + 96

= 90°

26). Both the angles (20x + 5)° and (24x - 1)° are consecutive interior angles.

Therefore, (20x + 5)° + (24x - 1)° = 180°

44x + 4 = 180

44x = 176

x = 4

Twice the larger of two consecutive integers is equal to fifteen less than three times the smaller. Find the integers.

Alexxandr [17]

Answer:

17,18

Step-by-step explanation:

let the smaller integer be "a" and the larger be "b"

Then 2b = 3a -15 ........................equ 1

but they are consecutive integers, b= a+1 ; substitute b into equ 1,thus,

2(a+1) = 3a - 15

2a + 2 = 3a-15

collect like terms,

2+15 =3a-2a

17 = a

b= a+1

b = 17+1

b=18.

The integers are 17,18

The sum of two numbers is 18. 5 times the first number subtracted from 4/7 of the second number is 14. Find the number.

Sergeu [11.5K]

Answer:

The sum of two numbers is 18.

5 times the first number subtracted from 4/7 of the second number is 14.

First number --> x

Second number --> y

x + y = 18 --> x = 18-y

5x - (4/7)y = 14

5 (18-y) - (4/7)y = 14

90 - 5y - 4/7 y = 14

-5.57 y = 14-90

y = 13.64

x = 18 - 13.64

x = 4.36
