Answer: x= 5
Step-by-step explanation: If angles 1 and 2 are supplementary, that means they add up to 180. So if angle 1 is 87, angle 2 has to be 180-87=93. Then the equation would be 15x+18=93. Subtract 18 on both sides. 15x=75. Divide by 15 and your answer is 5.
Answer:
0.6 or ![\frac{3}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D)
Step-by-step explanation:
Using the Pythagorean theorem (
) we get that the hypotenuse is 5.
so the cos V is adjacent over the hypotenuse. so if adjacent is 3 and hypotenuse is 5, the answer is
which equals 0.6 in decimal form.
Step-by-step explanation:
![3x + \frac{2}{4} x + 1 = 5x + \frac{1}{3} x + 2 \\ 1.833 x+ 1 = 0 \\ 1.833x = - 1 \\ x = 0.545](https://tex.z-dn.net/?f=3x%20%2B%20%20%5Cfrac%7B2%7D%7B4%7D%20x%20%2B%201%20%3D%205x%20%2B%20%20%5Cfrac%7B1%7D%7B3%7D%20x%20%2B%202%20%5C%5C%201.833%20x%2B%20%201%20%3D%200%20%5C%5C%201.833x%20%3D%20%20-%201%20%5C%5C%20x%20%3D%200.545)
0 is the starting pointing for equations that are for positive numbers. 0 sets an easy way to figure out problems that have negatives. 0 is important to solve any problem with integers, and decimals!
