I’ll give brainliest please help!! A canoe travels 9 miles per hour downstream and 1 mile per hour upstream.

Let x represent the canoe's speed with no water current in still water) and y

represent the speed of the water current, in miles per hour. Then the situation

can be represented by this system of equations:

x + y = 9

x- y = 1

Choose the two correct options.

A. The speed of the canoe in still water is 4 miles per hour.

B. The speed of the water current is 5 miles per hour.

C. The speed of the water current is 4 miles per hour.

D. The speed of the canoe in still water is 5 miles per hour.

step-by-step explanation:

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

a.for lorena 14 hours makes $126   for 16 hours she makes 144

for julie 6 hours makes $72 for 21 hours its $252

b. julie makes more money than lorena julie makes $12 an hour and lorena makes $9
