ladessa [460]

Answer

Explanation: To solve this question we will just need to consider some rules as represented below

\begin{gathered} -a(-b)=+ab \\ x^a*x^b=x^{a+b} \end{gathered}

Step 1: Once we understand both rules above we can use them to simplify our equation as follows

\begin{gathered} -w^3(-2w^3) \\ +2*w^3*w^3 \\ 2*w^{3+3} \\ 2w^6 \end{gathered}

Final answer: So the final answer is

2w^{6}

Answer:

The better buy is 2 ice cream cones for $3.00

Step-by-step explanation:

Step one:

given

You can buy 2 ice cream cones for $3.00

let us solve for the unit cost

3/2= $1.5 per  ice cream cone

Step two:

You can buy 4 ice cream cones for $7.00

let us solve for the unit cost

7/4= $1.75 per  ice cream cone

The better buy is 2 ice cream cones for $3.00 because a cone is $0.25 less expensive than  4 ice cream cones for $7.00.

Ms.Gibson made an initial deposit of $500 when opening a bank account. After the initial deposit, she deposited the same amount
Zigmanuir [339]
Let say the number of the months is t, the total amount of depo is a and a0 is the initial amount of money deposited. You can put it like this:
a= f(t) = a0 + x*t

You can solve the equation by inserting two of any t value. If you use f(8)-f(4) it will be
a0+ x(8)= 2500 
a0+ x(4)= 1500
___________-
8x- 4x= 1000
4x= 1000
x=250

Then the new equation would be:
a= a0 + 250*t
Putting f(4) value you can find a0
1500= a0+ 250*4
a0=1500-1000=500

The final equation would be
a= 1000+ 250*t
