Answer:

a. y= -5/2x -4

Therefore, the only answer possible is a.

If pie-0 =3.14159265359 what is pie time 160=
Zepler [3.9K]

Answer:

Hey!

To start this problem, we'll most likely need a calculator. Handling \pi can get a little messy, and tricky.

(also note that "pie" is a food, the mathematical term \pi, is pronounced "pie", but spelled "pi.")

Anyway, multiplying 3.14159265359..... (\pi) \cdot 160 = 502.654824574...... going on and on.

In general, these types of problems are better for a calculator if you want an exact answer. Otherwise, just resort to estimation. \pi is pretty close to 3.14.

160 \cdot 3.14 = 502.4, which is decently close to our other answer.

Hope this helps!

Marina spent $13.50 at the grocery store. She bought pears, kiwis, and pineapples. Pears cost $0.50 each, pineapples cost $1.50
MArishka [77]

Answer:

Number of pineapples= 10

number of pears = 19

number of kiwis = 10 -2 = 8

Step-by-step explanation:

Cost of a pear = $ 0.50

Cost of a pineapple = $ 1.5

cost of a kiwi = $ 0.3

Let the pineapples = p

Number of pears = 9 + p

Number of kiwis = p - 2

The cost is

0.15 p + 0.5 (9 + p) + 0.3 (p - 2) = 13.50

0.15 p + 4.5 + 0.5p + 0.3 p - 0.6 = 13.50

0.95 p = 9.6

p = 10
