You need to know sum of inner angles of a triangle. Then you can write the equation relating with X
Accuracy is how close a measured item is to the actual or true value and precision is how close the measured items are to being the same. So you could weight 5 apples. If each apple weights 2 lbs and you said that the 5 apples weight a total of 10lbs you are determining the precision. Precision is independent of accuracy. Accuracy would be if you put all 5 apples on the scale at one time and knew a exact amount.
Answer: Y = -2
Step-by-step explanation:
y + 4 = -y + 3
subtract 4 from both sides and add y to both sides
2y = -1
y = -2
Answer:

Step-by-step explanation:
You multiply 0.75 into everything in the parenthesis. 0.75 * 3.5a = 2.625a and 0.75 * -6b = -4.5b. Then you would add the two answers: 2.625a + (- 4.5b ). Since there are two different variables, you cannot add the two. However, if the variables were the same, you could add them and get -1.875 (a or b).
