It would be 4 because, on the right, it has 3 and 4. That is 7 and if you look at the scale it's balanced which means it would be the same on that side but it already has 3 so 4. So hold up your fingers and take 4 fingers up and add 3 fingers to that 4. How many is that? Count them all up and you'll get 7!

N+3=7. To find n, you need to have it by itself, so you can do that by subtracting 3 on both sides, so it would look like: n+3-3=7-3. Then you have n=4.

1.666666, any decimal or number that is repeating can be written in a/b format and b not equal zero is rational. Repeating decimals can be considered rational because they can be represented as a ratio of two integers.

Write the equation of a vertical line that passes through the point (–4, 4).
FinnZ [79.3K]
The question asks for a vertical line, and if it is vertical, it cannot be y = ... because that is horizontal. We also know it passes through the x-coordinate of -4, so the answer is x = -4.

What is the value of X. I will mark brainliest to the first 1 week right
Paraphin [41]

The two angles form a straight line and need to equal 180 when added together:


7x + 28 + 33 = 180

Simplify:

7x + 61 = 180

Subtract 61 from both sides

7x = 119

Divide both sides by 7

X = 17
