Twice the difference between 5 times a number and 6 equals 18:

2(5x-6)=18

We need to solve for x:

5x - 6 = 2(difference) = 18

The difference must equal 9.
In order for the difference to equal 9, x must equal 3.

5(3) - 6 = 2(difference) = 18

Let's solve:

15 - 6 = 2(9) = 18

Therefore, in this equation, x = 3.

Answer:

Step-by-step explanation:

2y-5 and 95 are vertical angles so they are equal

$2y - 5 = 95$

$2y = 100$

$y = 50$

3x and 144 form a linear pair angle so

$3x + 144 = 180$

$3x = 36$

$x = 12$

x=12 and y=50 so

$12 + 50 = 62$

Answer:

When y=276, x= 23

Step-by-step explanation:

Since they're directly proportional, when divided they have to equal the same.

180/15= 12 and 276/23= 12

Dot got a 75% on her test. She missed 12 questions. how many questions were on the test

AleksAgata [21]

Well, if it was out of 50, it would be 76%.

So the answer might be 50 questions total, but maybe there was 49 questions total.

I would probably go with 50 questions total.
