Let x = Mrs. D's salary last year
13% = 13/100 = 0.13
6500 is 13 percent of Mrs. D's salary, so:
0.13(x) = 6500
0.13(x)/0.13 = 6500/0.13
x = 50,000
Mrs. D's salary last year was 50,000 dollars.
The correct answer for solving for x is: x ≤ 9
Answer:
Mean is 18
Step-by-step explanation:
We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. ... And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18
A) y = 5/3x - 9
B) y = -x + 3
C) y = -2/7x + 1
D) y = 5x + 4
Answer:
x= 6
Step-by-step explanation:
by using Pythagoras theorem
(30)={(9x^2+ 16x^2)}1/2
30= 5x
x= 30/5
x= 6
