What number is 70% of 200

Answers

Answer 1
Answer: 70% = 0.7
0.7 of 200 = 0.7*200
                 = 140
So, 70% of 200 is 140
Answer 2
Answer: it's 140

200/x=100/70
(200/x)*x=(100/70)*x       - we multiply both sides of the equation by x
200=1.42857142857*x       - we divide both sides of the equation by (1.42857142857) to get x
200/1.42857142857=x 
140=x 
x=140

x ^(2)  - 8x = 3solve by factoring please. I really need help I have no clue how to solve by factoring like I forgot the steps so can u work the steps out also please

Answer:

x = 4 + √(19)

Step-by-step explanation:

To solve by factoring, complete the square by dividing 8 from 8x in 2. Then square the result 4 to get 16. Add 16 to both sides.

x^2 -8x = 3\n\nx^2 - 8x + 16 = 3 + 16\n\n(x-4)^2 = 19

The equation is now factored. To solve, take the square root of both sides and solve for x.

√((x-4)^2)  = √(19)\n\nx-4 = √(19) \n\nx = 4 + √(19)
