Answer: s(s+4)=7, 7 shelves

Step-by-step explanation:

I think it's easiest to find these type of answers by finding the common factors of a number. First 77, they are 1×77 & 7×11.so you can have 11 rocks on 7 shelves or 7 rocks on 11 shelves. The question states the number or rocks on the shelf is more than the number of shelves, so you must have 11 rocks on 7 shelves. You know you have 77 rocks, so the equation must equal 77. I plugged 7 in for s in the equations to determine the correct answer. 7(7+4)=77.

After paying 8.5% sales tax and leaving a 20% tip, Gwyn paid $57.29. What was the cost of the meal before tax and tip? Round you
olga nikolaevna [1]

Answer:$33.41

Step-by-step explanation:

I converted the percentages to decimals and subtracted them from 1.

(Btw x stands for the cost before tip and tax)

This was the equation I came up with based on what was given to me;

57.29 = (1-0.085)x + (1-0.2)x

57.29=0.915x + 0.8x

57.29=1.715x

Divide both sides by 1.715 and should get 33.40524781

Since we are rounding to the nearest cent, the answer would be $33.41

If a number is divisible by 2 and 3 then it is divisible by 6
IrinaVladis [17]
Yes it is it is because So for a number to be divisible by 6, it must also be divisible by 2 and 3. Therefore, we need to check if a number is even and then check if the sum of the digits is divisible by 3.
