Answer:
What
Step-by-step explanation:
What language
Is that
Let, the speed of boat = x
Speed of current = y
So, x + y = 280/7
x + y = 40 ---- first equation
x - y = 280/14
x - y = 20
x = 20 + y
Substitute this value of x in first equation,
20 + y + y = 40
2y = 40 - 20
y = 20/2
y = 10
Substitute this in first equation,
x + 10 = 40
x = 30
In short, Speed of Boat = 30 mph, & speed of current = 10 mph
Hope this helps!
Answer:
Step-by-step explanation:
Convert 2y=-3x+2 into y=mx+b form
Y intercept is 1, slope is -3/2
Graph looks like this:
The first thing you should do is do everything in parenthesis.
So lets start:
(2*4) = 8
(3*55) = 165
(2+7) = 9
Now we add and subtract the numbers:
8 + 165 - 9 = 164
So that means that the answer is 164.
Hope this helps!!! :)
