Answer:

Step-by-step explanation:

The perimeter means the sum of all sides. A square has four equal sides, and we know each side is "y".

y + y + y + y

Then simplify that expression. Collect like terms, which are numbers with the same variables. All of them are "y", so combine them by adding.

y + y + y + y

4y Simplified expression

Remember an expression means there is no equal sign.

P = 4y is an incorrect answer.

That would be an equation.

two pounds of grapes cost $6 . complete the table showing the price of different amounts of grapes at this rate

Degger [83]

Answer:

Table shown below

Step-by-step explanation:

To solve this problem let's use proportions.

If 2 pounds of grapes cost $6, half the amount will cost half the dollars, so the last row will have $3 in the price

For the second row, we know the price is $1, that is, one-sixth of the original given price. It should correspond to one-sixth of the amount of grapes or 2/6 pounds.

Simplifying the fraction, we get 1/3 or 0.33 pounds

Donna takes classes at both Westside community college and pinewood community college. at westside , class fees are $98 per cred

Alex777 [14]

Answer:

Expression for the combined total dollar amount she paid for her class fees is (2185 - 17 w)

Step-by-step explanation:

Let Donna is taking w credit hours at Westside.

Total combined credit hours at two schools = 19 hours

So, the number of credit hours at Pinewood = 19 - w

The per hour fees credit of Westside community college = $98

So, the total fees paid for w hours = w x Fees per hour

= w ( $98) = $(98w)

⇒The fees Donna pays at Westside community college = $ (98 w)

The per hour fees credit of Pinewood community college = $115

So, the total fees paid for (19 -w) hours = (19 -w) x Fees per hour

= (19 -w) ( $115) = $(2185 - 115 w)

⇒The fees Donna pays at Pinewood community college =$(2185 - 115 w)

Hence, the total fees paid by Donna

= Fees at Westside + Fees at Pinewood

= $ (98 w) + $(2185 - 115 w)

= $(2185 - 17 w)

Hence, expression for the combined total dollar amount she paid for her class fees is $(2185 - 17 w)

Please help with these two math problems 1. 7^x ÷ 7^y = 2. z^10x^y ÷ z^5 =

IceJOKER [234]

Answer:

1. 7^(x-y)

2. z^5x^y

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)/(a^c) = a^(b-c)

$\dfrac{7^x}{7^y}=\boxed{7^{x-y}}$

$\dfrac{z^{10}x^y}{z^5}=x^yz^{10-5}=\boxed{z^5x^y}$
