Answer:

64 nickels and 24 dimes

Step-by-step explanation:

Let there be x nickels and y dimes

The number of nickels is 8 less than 3 times the dimes

i.e. x = 3y-8

Value of the coins = 5x+10y

= 560 cents (given)

Substitute x value in the second equation

5(3y-8)+10y = 560\\25y = 600\\y =24\\

Substitute in

x = 3y-8\\=64

There are 64 nickels and 24 dimes.

m_a_m_a [10]
To get how many customers Sam has, write an equation that will relate to the gross profit. Let n be the customers. Since for 52 weeks, Sam charges $25 per week per person, multiply n by the number of weeks and the charge. The equation is written as $88,400 = 52 weeks x $25 per week x n persons. Divide $88,400 by the product of 52 weeks and the $25 charge. The answer will be 68. The annual operating expense $48,000 is just there to make confusion.

Bond [772]

Answer:

Part 1) \frac{a^4}{4b^2}

Part 2) -\frac{v^9}{w^6}

Step-by-step explanation:

we know that

When divide exponents (or powers) with the same base, subtract the exponents

Part 1) we have

\frac{3a^{2}b^{-4}}{12a^{-2}b^{-2}}=(\frac{3}{12})(a^{2+2})(b^{-4+2} )=\frac{1}{4}a^{4}b^{-2}=\frac{a^4}{4b^2}

Part 2) we have

\frac{v^3w^{-3}}{-v^{-6} w^3} =-v^{3+6}w^{-3-3}=-v^9w^{-6}=-\frac{v^9}{w^6}
