3. Write a simplified algebraic expression for<br> the model
ICE Princess25 [194]

The simplified algebraic expression for the model is x = -1

<h3>What are algebraic expressions?</h3>

Algebraic expressions are known as mathematical statements gotten when operations such as addition, subtraction, multiplication, division, etc. are operated or used on variables and constants

From the figure given;

We have:

  • x
  • x
  • -x
  • (- 1) ^6
  • (1) ^5

Now, let's add the variables

= x + x - x

= 2x - x

= x

For the constants

= -1^6 = -1

= 1 ^5 = 1

= 1 × -1 = -1

Thus, the simplified algebraic expression for the model is x = -1

You buy school clothes during a sale when everything in the store is 15% off. Which of the following could describe
Savatey [412]

Answer:

(29.99 + 18.65 + 32.59) 0.85 = 0

(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0

Step-by-step explanation:

The 15% off represents percentage discount. The relationship between percentage discount and total cost is given by the equation;

Actual cost - (Percentage discount) Actual cost = Total cost

The correct options are;

(29.99 + 18.65 + 32.59) 0.85 = 0

(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0

Amy has 1/2 hour to do 3 chores. She plans to spend the same fraction of an hour on each chore. She wants to use the number line
Natali5045456 [20]
Point A would be zero; Point B, the end of the 1/2-hour time interval, would be 1/2 (representing 1/2 hour).  Then Amy needs to subdivide the interval A to B into three equal time intervals and to determine the length of each of these subintervals.

I would begin with 1/2 and divide that by 3:  

1
--
2
====
   3
   --
    1

Inverting the fraction in the denom. and multiplying, we get

1      1       1
-- * ---- = -----
2      3        6

So Amy will spend 1/6 th of an hour, or 10 minutes, on each chore.

Note that 3 times 1/6 comes out to 1/2 (hour), which is were we started.
