Answer:
a) 1. Equivalent expression
b) 3. (wx)yz
c) 2. wx(yz)
Step-by-step explanation:
1. According to the associative property, the result of the addition or the multiplication of three or more numbers are the same irrespective of the order of the grouping of the numbers.
(a + b) + c = a + (b + c)
That is the result of the equation is not affected by the rearrangement of the parenthesis to group the numbers
In the given question
w(xy)z = (wx)yz
w(xy)z = wx(yz).
Answer:
Simplifying the expression: we get
Step-by-step explanation:
We need to simplify the expression:
First we will solve terms inside the bracket
Converting mixed fraction into improper fraction, we get:
Replacing the term:
Now, taking LCM of: 5,3,4,2 we get 60
Now multiply 60 with each term inside the bracket
Now, combine like terms
Now, multiply all terms with 2
So, Simplifying the expression: we get
Supplier A: 5.25 per bushel and deliver fee of 3 per bushel
Supplier B: 6.50 per busher and flat delivery fee of $1500 each week
500 bushels of grain each week.
Supplier A: 5.25x + 3x = 5.25(500) + 3(500) = 2,625 + 1,500 = 4,125
Supplier B: 6.50x + 1500 = 6.50(500) + 1500 = 3,250 + 1,500 = 4,750
Supplier B would cost more if the company buys 500 bushels of grain per week.
Answer:
To start this question we multiply both sides of (n + 5)/-16 = -1 by -16. We get
n+5=16, because of this. Now we can solve for n by subtracting 5 on both sides. We get n=11 so the answer is your first choice or 11.
Step-by-step explanation: Since the equation of this line is written in
slope-intercept or y = mx + b form, its slope or m is represented by the
coefficient of the x term which in this case is 8/5.
It's y-intercept or b is represented by
the constant term which in this is -5.
To graph the line, start with the y-intercept of -5.
So go down 3 units on the y-axis, plot a point at (0, -3).
From there, take your slope of 8/5, so rise 8 units
and run 5 units the right which should leave you at (5, 3).
Graph the line through those points.
