Yes, it's y= 1/2x because it's 1/2 miles (y) per x weeks
Answer:
x + 6 = 33
Step-by-step explanation:
6 more than x means there's an increment in the value of x by addition of 6
x + 6 = 33
This leads to an algebraic linear equation. x is an unknown variable and can be solved for
we subtract 6 from both sides of the equation
x + 6 - 6 = 33 - 6
x = 27
Therefore, we can say 6 more than 27 is 33
There are 52 weeks in a year. The question is asking how much is the annual salary.
R = speed in still water
r + c = speed with current
r - c = speed against current
3.5(r + c) = 70
r + c = 20
c = 20 - r
4(r + c) = distance from pier to pier
5(r - c) = distance from pier to pier
4(r + c) = 5(r - c)
4(r + 20 - r) = 5(r - 20 + r)
80 = 10r - 100
180 = 10r
18 = r
The speed in still water is 18 km/hour
