At a student bake sale cakes sold for $4 each and pies sold for $5 each. The students sold a total of 75 cakes and pies

and made $340. Which pair of equations would determine

the number of each ticket sold?

а.

x - y = 75

4x - 5y = 340

B)4x - y = 75

5y - x = 340

Oь

Ос

x + y = 75

4x + 5y = 340

Od

x - y = 340

4x - 5y = 75

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

you would need to also lose 1 point for each of the other outcomes for it to be fair.

step-by-step explanation:

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
