Answer:
176800 per year
Step-by-step explanation:
There are 52 weeks in 1 year
3400 per week * 52 weeks per year
176800 per year
5n+10d=595
n=nickels, d=dimes
101 nickels, 9 dimes
99 nickels, 10 dimes
117 nickels, 1 dime
(8x+12)+(3y-9)= 8x+3y+3=78
subtract 3 from both sides
8x+3y=78
subtract 8x from both sides
3y=-8x+78
divide both sides by 3
y=-8/3x+26 or y=-2.666666666x+26
substitute for y
8x+3(-8/3)+26=78
subtract the 26 from both sides
8x+3(-8/3)=52
distribute the 3
8x- 7.99999999998=52
add the -7.999999999998 to bother sides
8x=60
divide both sides by 8
x=7.5
substitute for x
8(7.5)+3y=78
60+3y=78
subtract 60 from both sides
3y=18
divide both sides by 3
y=6
so x=7.5 and y=6
Can you tell me a specific name and what grade this is, Cause I have multiple ways of doing this
Let the speed of the current be x and the speed of the canoe in still water be y, then

Adding the two equations, we have:

From any of the equations, we have that x = 2
Therefore, the speed of the current is 2 miles per hour while the speed of the canoe in still water is 5 miles per hour.
