Answer:

Step-by-step explanation:

The question lacks appropriate diagram. Find the diagram attached.

Slope is the change in coordinate of the y coordinate to the x coordinate.

Mathematically, slope m = ∆y/∆x

From the diagram ∆y is the same as 3 (along the vertical) while ∆x is the same as 1 (along the horizontal)

m = ∆y/∆x = 3/1

∆y/∆x = 3/1

y/x = 3/1

Cross multiply

y × 1 = 3 × x

y = 3x

Hence the slope of the line is y = 3x

Nitella [24]
Hey there, Elizabeth76265!

If the owner left only 3 cans of food for 5 days, that means that we have to divide those cans of food so we can just do simple math and divide 3 by 5
\frac{3}{5} and you get 0.6

So the cat must eat 0.6 of each can everyday.

Dorian buys 2 pounds of almonds for $21.98 and 3 pounds of dried apricots for 26.25 which is less expensive per pound how much l
Anit [1.1K]

Answer:

The apricots are $2.24 less expensive per pound.

Step-by-step explanation:

To find the price per pound of each product divide the price Dorian by the number of pounds Dorian bought:

Almonds: 21.98 ÷ 2 = 10.99

Almonds cost $10.99 per pound.

Apricots: 26.25 ÷ 3 = 8.75

Apricots cost $8.75 per pound.

The apricots are less expensive per pound. To find how much less expensive they are compared to the almonds, subtract the cost of the apricots per pound from the cost of the almonds per pound:

10.99 - 8.75 = 2.24

The apricots cost $2.24 less per pound than the almonds do.
