I think you are trying to say,
x5=5x
That is the commutative property.
It states that a*b= b*a
In other words, it doesn't matter when you multiply which order it is in.
I hope this helped!

Well this is actually quite a difficult one.
Simplify each
1. y = -4/3x + 5
2. y = 3/4x - 2
3. y = x - 7
4. y = -5
I actually don’t see one that would work for a parallel line. Are you sure that this is everything because number 4 wouldn’t work for anything considering it doesn’t have a slope. So I would say either B or C but I don’t see either working unless I’m just missing something.
Answer:
there are 400 meters in a track
400 times 12 = 4800
4800 divided by 1600 =3

Step-by-step explanation:
Answer:
At the end of the year, Marc will have 1.10 times the amount invested
Step-by-step explanation:
Let
x -----> the amount that Marc wishes to invested
Remember that
At the end of the year the amount of money will be the amount invested multiplied by 1.10
so
1.10x
therefore
At the end of the year, Marc will have 1.10 times the amount invested
<em>Alternative Method</em>
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula
Let us calculate the area of the walk.
Since the width of the walk is 3 feet, and the walk will be placed all the 4 sides,
Length of the plot including walk = 20 + (2 × 3) = 20 + 6 = 26 feet.
Breadth of the plot including walk = 30 + (2 × 3) = 36 feet.
Area of the plot including walk = 26 × 36 square feet.
Area of the plot = 20 × 30 square feet.
Area of the walk = (26 × 36) - (20 × 30)
= 936 - 600
= 336 square feet.
= square yards
= 37.3 square yards
Cost of the walk per square yard = $12.25.
Therefore, total cost of the walk = 12.25 × 37.3 = $456.92.
