For this problem, we can move all the X's to one side and all the regular numbers to the other. 

7x comes over and become -7x 

10 goes over and becomes -10.

5x+7x-7x=-3-10+13+12.

-3-10=-13, which cancels out the positive 13.

-7x+7x=0 which cancels each other out. 

Now, 5x=12

Divide each side by 5.

x=2.4  <--- final answer.

Hey there! :) 

5x + 10 + 7x = -3 + 13 + 7x + 12

Add like terms.

(5x + 7x) + 10 = (-3 + 13 + 12) + 7x

Simplify.

12x + 10 = 22 + 7x

Now, we have to isolate x. To do that, we must start out by subtracting 10 from both sides.

12x = 22 + 7x - 10

Then, subtract 7x from both sides.

12x - 7x = 22 - 10

Simplify.

5x = 12

Divide both sides by 5.

x = 12/5 OR as a decimal, x = 2.4

Answer:

About 5.5% decrease

Step-by-step explanation:

Here, we want to calculate the percentage increase or decrease and its value.

The first thing to do here is to check if we are going to have a decrease or an increase.

since the value before the change is higher than the value after the change, then what we have is a decrease.

Mathematically, the percentage decrease is calculated as follows;

% decrease = (old value - new value)/old value * 100%

old value = 163 feet

new value = 154 feet

% decrease = (154-163)/163 * 100%

% decrease = -9/163 * 100%

% decrease = -5.52%

Thus the best answer is about 5.5% decrease

eimsori [14]

1. use sin

inverse of sin(44/57) = 50.5 ---> 51°

2. use tan

inverse of tan(6/8) = 36.8 ---> 37°

3. use cos

inverse of cos(20/31) = 49.8 ---> 50°

4. use sin

inverse of sin(37/58) = 39.6 ---> 40°
