Answer:
X = 3
Step-by-step explanation:
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:
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

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
The movie would be 1 hour 45 minutes long
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.
