Answer:
x = 2/9 (or = 0.222)
Step-by-step explanation:
1/x + 1/(3x) =6 (multiply both sides by 3x)
(1/x) (3x) + [1/(3x)](3x) =6 (3x)
3 + 1 = 18x
4 = 18x
x = 4/18
x = 2/9 (or = 0.222)
Answer:
Well you can try to use a calculator, like the one on google. I can try to help if you really need it.
Step-by-step explanation:
Answer:
9.233 ft, 23.233 ft
Step-by-step explanation:
If the shorter leg is x, then the longer leg is x+14 and the Pythagorean theorem tells you ...
x^2 + (x +14)^2 = 25^2
2x^2 +28x +196 = 625
x^2 +14x = 214.5
x^2 +14x +49 = 263.5
(x +7)^2 = 263.5
x = -7 +√263.5 ≈ 9.23268
The two leg lengths are √263.5 ± 7 feet, {9.23 ft, 23.23 ft}.
The correct equation would be Y=1/2x+4 :)
This is true because both equations have the same slope therefore they are parallel and the equation above also includes point (-6,1).
First, start off by listing a few of the numbers that follow the first three clues to see if you can narrow it down.
7,111,111
7,333,333
7,555,555
etc.
Then, start adding up digits to see if you're getting close.
7+1+1+1+1+1+1 = 13
7+3+3+3+3+3+3 = 25
7+5+5+5+5+5+5 = 37
Since 7,555,555 is too high, we step it down to 7,555,333
7+5+5+5+3+3+3 = 31
7,555,333 will work as an answer, as well as 7,333,555, since it's the same amount when the digits are added together.
