5 ^6 − 5 ^11 = 5 x ( 1 − 5 y ) what is the value of x and y
Eva8 [605]
Is it 5^6 - 5^11 = 5x × (1-5y)?
5^6 - 5^11 = 5^(6-11) = 5^(-5) = 1/(5^5)
So 1/3125 = 5x - 5(5y)
1/3125 = 5(x-5y)
1/3125/5 = x-5y
0.000064 = x - 5y

muminat

A store is giving away a $10 dollar coupon to every 7th person to enter the store and a $25 coupon to every 18th person to enter the store.

To find the first person to get both coupons, you have to find the LCM of 7 and 18. First list the multiples of each number.

7 - 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119, 126, 133

18 - 18, 36, 54, 72, 90, 108, 126, 144

The common multiples are bold. The <u>126th person</u> will be the first to get both coupons.

wlad13 [49]

Long piece:  5x + 3

Short piece: x

Long   + Short = Total

5x + 3 +    x     = 45

6x + 3 = 45

6x = 42

x = 7

Long piece:  5x + 3   = 5(7) + 3   = 35 + 3   = 38

Answer: short = 7 ft, long = 38 ft
