What is the value of v? 1 / 4 (v – 7) = 2

1 answer:

6 0

1/4 (v - 7) = 2

1/4v - 1/4 (7/1) = 2

1/4v - 7/4 = 2

1/4v = 15/4

Multiply by 4/1 on both sides to get v

(4/1) 1/4v = 15/4 (4/1)

v = 60/4

v = 15

16. Find the values of x and y.<br> (2y + 5)<br> (5r - 17)<br> (3r - 11)

Alinara [238K]

(5x - 17) + (3x - 11)= 180 [ Linear Pair ]
= 8x - 28= 180
= 8x= 208
= x = 208/8
= x = 26

3x-11
= 3*26 - 11
=67

Now, we have:
(2y+5)+90+(3x-11)=180 [Linear Pair]

Substituting (3x-11),
(2y+5) + 90 + 67= 180
= (2y+5)+157= 180
= 2y + 162= 180
= 2y= 18
=y = 18/2
=y= 9

Therefore, x= 26, and y= 9

john rode 2 kilometers on his 6ike.his sister sally rode 3000 meters on her bike.who rode the farthest and how much farther did

artcher [175]

1 kilometer is 1000 meters. Therefore, 2 kilometers is 2000 meters. 2000 is greater than 3000, so Sally rode farther by 1000 meter, or 1 kilometer.

Aneli [31]

Answer:

$\huge\boxed{x=-18}$

Step-by-step explanation:

In order to solve this, we are trying to find the value of $x$ . Basically, $x$ is a placeholder for a number that is unknown. Some number minus 3 is equal to 21.
