Answer: x = 12

Step-by-step explanation:

We know that the whole angle is 90°. Therefore, we can set up our equation like this:

90 = 50 + 3x + 4

Lets combine like terms:

90 = 54 + 3x

Now, let’s isolate the variable. To do this, we have to move 54 to the other side, making it negative.

90 - 54 = 3x

36 = 3x

Now, you divide, the leave the variable by itself.

\frac{36}{3} = \frac{3x}{3}

Therefore, x = 12.

We can see that there is a right angle in the figure and that both the 50° and (3x + 4)° angle make a complementary angle (90°).

We can write an equation:

90 = 50 + 3x + 4

Solve for x.

90 = 50 + 3x + 4

~Combine like terms

90 = 54 + 3x

~Subtract 54 to both sides

90 - 54 = 54 - 54 + 3x

~Simplify

36 = 3x

~Divide 3 to both sides

36/3 = 3x/3

~Simplify

12 = x

Therefore, x = 12

Best of Luck!

2. 3/4(-4 + 4x) = -3 + 3x   3/4 times 4 is 3, so if you distribute 3/4 (-4 + 4x), you will get -3 + 3x. 

3. -0.113(-4x - 4) = 0.452x + 0.452   0.113 times 4 is 0.452, but you need to make sure to have the correct signs. Since the product is positive and -0.113 is negative, you would have to multiply it by a negative to get the product.

If you're having trouble with multiplying by fractions, just use repeated addition in your head. For example, for the first problem, instead of trying to tackle 3/4 times 4, think 3/4 + 3/4 + 3/4 + 3/4.

3/4 + 3/4 = 6/4
6/4 + 3/4 = 9/4
9/4 + 3/4 = 12/4
12/4 = 3

For the second problem, when multiplying by a decimal, just do what you'd normally do for multiplication. When you get to the end, count how many digits you had behind the decimal before, and put the decimal in the corresponding space for the answer.

0.113
x    4
0452

There are 3 digits behind the 0 in 0.113, so there should be 3 digits behind the decimal in the answer. So, the answer should be 0.452.

Hope this helps!

Here I'll Simplify it to show the work.
You need PEMDAS

9(2*2+4÷2)
9(4+4÷2)
9(8÷2)
9(4)
9(4) = 9 × 4 = 36

The Answer is 36.
