y + 5 = -3/4 x
Subtract 5
from each side: y = -3/4 x - 5
In this form, we can read the slope and y-intercept directly.
Slope = -3/4
y-intercept = -5
Answer
Option C : 2214(5)
Solution
The given number is 465 in base 8. To convert this number to base 5,we need to convert this number to base 10, then only we can compute the number in base 5
Step1 : Convert 465 to the base 8 to base 10
4 x 82=256
6 x 81=48
5 x 80=5
Adding 256 + 48+ 5 = 309(10)
Step2 : Convert 309(10) to base 5
5 | 309
5 | 61 |4
5 | 12 | 1
5 | 2 | 2
5 | 0 | 2
Therefore Answer = 2214(5 )
So she walked during this time with <span>4 miles per hour (x*4)
during
the rest of the way (which is 0.7-x, as the whole way took her 42
minutes, so the rest is 0.7-x) she walked with 5 miles per hour - the
distance was (0..7-x)*5 m/h
the total distance was 3 miles, so if we sum the two distances, we will get 3 miles:
x*4+ (0.7-x)*5=3
let's remove the bracket:
4x+0.7*5-5x=3
</span>
<span>4x+3.5-5x=3
subtract 3.5 from both sides:
4x-5x=3-3.5
-x=-0.5
multiply both sides by (-1)
x=0.5:
so she walked for half an hour alone, that is for 30 minutes!</span>
Whoah that's complicated i don't think i can help srry <span />
