Answer:

z/y

Step-by-step explanation:

when dividing with exponents, you simply subtract the variables w exponents

y^5 - y^6 = y^-1 (which is equal to 1/y)

z^3 - z^2 = z^1 (which is equal to z/1)

1/y * z/1 = z/y

Mrs. Salinas bought 10 pounds of a mixture made of M&Ms and peanuts. M&Ms sell for $3 pound. Peanuts sell for $2 pound.

jek_recluse [69]

Answer:

Mrs. Salinas buys 4 ounces M&Ms and 6 ounces Peanuts.

Step-by-step explanation:

Given,

Total weight of the mixture = 10 pounds.

Total money Mrs. Salinas paid = $24.

We have to find out the weight of each M&Ms and peanuts.

Solution,

Let the weight of M&Ms be x.

And the weight of peanuts be y.

Since total weight of the mixture is 10 pounds.

So, we can frame it in equation as;

$x+y=10\ \ \ \ \ equation\ 1$

Again, Total money paid by Mrs. Salinas is the sum of weight of M&Ms multiplied by price for each ounce and weight of peanuts multiplied by price for each ounce.

So, we can frame it in equation as;

$3x+2y=24\ \ \ equation\ 2$

Now, multiplying equation 1 by 2, we get;

$2(x+y)=10\times2\\\\2x+2y=20\ \ \ \ \ equation\ 3$

Now subtract equation 3 from equation 2, we get;

$(3x+2y)-(2x+2y)=24-20\\\\3x+2y-2x-2y=4\\\\x=4$

On substituting the value of x in equation 1, we get;

$x+y=10\\\\4+y=10\\\\y=10-4\\\\y=6$

Hence Mrs. Salinas buys 4 ounces M&Ms and 6 ounces Peanuts.

A salesperson at a jewelry store earns 5% commission each week. Last week, Jarrod sold $640 worth of jewelry. How much did he

Aleksandr-060686 [28]

Answer:

$32

Step-by-step explanation:

To find the commission, multiply the rate by the sales:

commission = 5% × $640 = $32

He made $32 in commission.

Additional comment

Many calculators and all spreadsheets can work with percentages directly. If yours can't, or if you can't do this arithmetic mentally, you can use the equivalent decimal or fraction for 5%.

5% = 5/100 = 0.05 = 1/20

Then 5% × $640 = $640/20 = $64/2 = $32.
