Let the 'something' be 'x' Hence x - 8 = 41 Add '8' to both sides x - 8 + 8 = 41 + 8 x - 0 = 49 x = 49 THR answer.
We will do this in steps. -4 x -2 = 8. -7 x 7 = -49. 8 + (-49) = -41.
(x - 8)2 + (y - 4)2 = 49
Call your number "x", write an equation, and solve it: 8x = x + 49 7x = 49 x = 7
To find a percent of a number, follow this rule. Suppose you have a number X, and you want to know what is P percent of X. Then P percent of X is (P/100) * X So in this case, you want to find (49/100) * 8, which is 3.92. For another example, what is 75 percent of 8? Then you have (75/100) * 8, which is 6. What is 100% of 8? It is (100/100) * 8, which is 8.
