Ms. McDuffy bought 2 1/2 yards of fabric that cost $7.90 per yard. She also bought 3 3/4 yards of fabric that cost $9.96 per yard. What is the total cost of the fabric?
Answers
The total cost of the fabric is $57.1
What is unit rate?
A unit rate means a rate for one of something. We write this as a ratio with a denominator of one.
Given that, Ms. McDuffy bought 2 1/2 yards of fabric that cost $7.90 per yard. She also bought 3 3/4 yards of fabric that cost $9.96 per yard
Cost of fabric with unit rate = $7.90
= $7.90 × 5/2 = $19.75
And, cost of fabric with unit rate = $9.96
= $9.96 × 15/4 = $37.35
Total cost = $37.35 + $19.75 = $$57.1
Hence, the total cost of the fabric is $57.1

Answer:
1/2a = -5
a = (-5 x 2) : 1
a = -10
8 - b = 9,5
b = 8 - 9,5
b = -1,25
0,1 = -10c
c = 0,1 : -10
c = -0,01

Answer:
b. Elisondra will order first approximately 10 times.
e. Each person will order first approximately the same number of times.
Missing Problem Statement:
Elisondra is eating at a restaurant with three friends. They want to choose at random who will order first. If you model the situation with the spinner, how many equal-sized sections should the spinner have?
What is the theoretical probability of the spinner landing on Elisondra's section?
Step-by-step explanation:
Now, before we proceed to the current options in the problem statement. We need to model the situation with the spinner, how many equal sized sections should spinner have?
Since Elisondra is with her 3 friends, so we have a total of 4 people.
So the spinner should have 4 equal sized sections
Theoretical Probability of spinner landing on Elisondra's section =
In the given statement:
Spinner is used to decide who orders first during 40 visits.
The options that apply are:
B) Elisondra will order first approximately 10 times. As:
Theoretical Probability of spinner landing on Elisondra's section in 1 spin =
Theoretical Probability of spinner landing on Elisondra's section in 40 spins = =10 times
E) Each person will order first approximately the same number of times, as probability of any person ordering first is in 1 spin.
Option (A), (C) and (D) do not apply as it is not possible.
Answer:
B) Elisondra will order first approximately 10 times.
E) Each person will order first approximately the same number of times.

3. solve 3(2x-1)/4= x + 7/2
the 3(2x-1) is over the 4 and the x + 7 is over the 2 i really dont understand them

For number one, there will be an infinite number of solutions, as there are two placeholders.
3x - 2y = 6
It seems we can use the intercept method.
3x - 2(0) = 6
3x = 6
Divide both sides by 3
x = 2
This is one solution: (2,0)
3(0) - 2y = 6
-2y = 6
Divide both sidees by -2
y = -3
This is another solution: (0,-3)
You should now be able to draw the line.
If you want intercept form for this equation, just manipulate the equation in order to get the y = mx + b form.
Subtract 3x from both sides
-2y = -3x + 6
Divide both sides by -2
For the second problem, simply manipulate the equation.
Distribute
Subtract 2x from both sides
Add 6 to both sides
For the third problem, do the same thing.
We must first multiply both sides by 4.
Distribute
Subtract 4x from both sides
Add 3 to both sides
Divide both sides by 2
