Answer:

The value of x would be 20

Step-by-step explanation:

To solve this triangle, we need to first note that all triangles have 180 degrees. So we can add these all together and set equal to 180.

40 + 3x + 4x = 180

40 + 7x = 180

7x = 140

x = 20

Factor the following expression. 36y - 12

Hey there!

36y - 12

FIRST LOOK AT THE GCF (Greatest Common Factor)

36y: 1, 2, 3, 4, 6, 9, 12, 18, 36, and y

12: 1, 2, 3, 4, 6, and 12

GCF: 12

So, 12 would most likely be number before you make your parentheses

12(?y - 1)

The numbers in your original equation both share 3 & -1

So, therefore the factor form of your equation should be: 12(3y - 1)

Answer: 12(3y - 1)

Good luck on your assignment & enjoy your day!

How to you solve -15=y-62

sdas [7]

First move the (Y) to the other side of the equal sign,
$- y - 15 = - 62$
Then subtract add (15) on both sides
$- y = - 47$
Since a variable can't be negative just divide by (-1) on both sides,
$\frac{ - y}{ - 1} = \frac{ - 47}{ - 1}$
The answer would be,
$y = 47$
Hope this helped
