Answer:
-14/11
Step-by-step explanation:
when dividing a fraction, you flip the second fraction and turn the division sign into multiplication
so now you have -4/11 x 7/2
4 is divisible by 2 so you have: -2/11 x 7/1
now multiply -2 with 7 and 11 with 1: -14/11
Subtract:
(7x + 3) - (2x + 1)
Your answer should be in simplest terms.
Enter the correct answer.

An online auction charges sellers a flat fee of $1.20 and 2% of the amount of the sale. Let A be the amount of the sale in
dollars and C be the charge of the online auction. Explain whether the solutions A = -5 and C=1.1 are viable. (1 point)
O The solutions are not viable because the amount of the sale cannot be negative.
O The solutions are viable because the amount charged is positive.
O The solutions are not viable because the amount charged is not a whole number
O The solutions are viable because the amount of the sale is an integer.
Answer: The solutions are not viable because the amount of the sale cannot be negative.
Step-by-step explanation:
The solution A = -5 is not viable because A represents the amount of sale in dollars and so cannot be a negative number. The minimum amount that a person can make from sales is $0 so anything less than that is not viable.
For instance, if you are selling shoes for $4 each and make no sales in the day, your sales would be $0. It is not possible that your sales would be -$4.
Which quadratic equation has roots –2 and 1/5?
a
5x^2 + 9x – 2 = 0
b
5x^2 – 11x + 2 = 0
c
x^2 + 4x + 4 = 0
d
5x^2 – 9x – 2 = 0
Answer:
The equation [tex]5x^2\:+\:9x\:-\:2\:=\:0[/tex] has roots –2 and 1/5.
Hence, the option 'a' is the correct answer.
Step-by-step explanation:
Checking the equation
[tex]5x^2\:+\:9x\:-\:2\:=\:0[/tex]
putting x = -2 in the equation
[tex]5\left(-2\right)^2\:+\:9\left(-2\right)-\:2\:=\:0\:[/tex]
[tex]2^2\cdot \:\:5-9\cdot \:\:2-2=0[/tex]
[tex]2^2\cdot \:5-18-2=0[/tex]
[tex]20-20=0[/tex]
[tex]0=0[/tex]
L.H.S=R.H.S
putting x = 1/5 in the equation
[tex]5\left(\frac{1}{5}\right)^2\:+\:9\left(\frac{1}{5}\right)-\:2\:=\:0\:[/tex]
[tex]5\left(\frac{1}{5}\right)^2+9\cdot \:\frac{1}{5}-2=0[/tex]
[tex]\frac{1}{5}+\frac{9}{5}-2=0[/tex]
[tex]2-2=0[/tex]
[tex]0=0[/tex]
L.H.S=R.H.S
As putting x = -2 and x = 1/5 satisfy the equation.
Therefore, the equation [tex]5x^2\:+\:9x\:-\:2\:=\:0[/tex] has roots –2 and 1/5.
Hence, the option 'a' is the correct answer.

No the size of a pack cannot be represented as a function of its price.
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
It really depends, but the size of the pack can affect the pricing, if it is price by weight.
As, we know that function have have only one input value with their corresponding output.
But here the input value for rice packs 1.90 have two output values one is 850 and another 950.
Hence, the table cannot be represented as Function.

Step-by-step explanation:
Order the sides of the triangle from shortest to longest.
Answers:
Shortest Length = LNMiddle Length = LMLongest Length = MN========================================
Explanation:
Let's find the missing angle.
For any triangle, the three interior angles always add to 180
L+M+N = 180
75+50+N = 180
N+125 = 180
N = 180-125
N = 55
So we know the three angles of the triangle are
L = 75M = 50N = 55We see that M = 50 is the smallest angle, so the smallest side is the segment opposite this angle. The smallest side is LN. The smallest side is always opposite the smallest angle.
Similarly, the largest side is always opposite the largest angle. The largest angle here is L = 75, so the largest side is MN.
The middle side must therefore be LM.
The diagram below shows a visual summary.

Answer:
140
Step-by-step explanation:
AEF and DFE are opposite interior angles, so they are equal to each other
you can set the equation to 2x + 60 = 3x + 20
subtract 2x from both sides: 60 = x + 20
subtract 20 from both sides: 40 = x
plug in the value of x to the equation for AEF: 2(40) + 60
you get AEF is 140

A sale is going on at a sports store. A jersey is on sale for 20% off its original price of $250.00, plus GST of 5% what is the total cost of the jersey?
A.
$210.00
B.
$185.00
C.
$200.00
D.
$168.00
Answer:
Total cost of jersey = $210
Option A is correct option
Step-by-step explanation:
Original price of jersey = $250
Sale price is 20% of Original price i.e 20% off $250
Now finding 20% off 250
[tex]20\% \ of \ 250\\=\frac{20}{100}\times 250\\=50[/tex]
So there will be discount of $50
The Price of jersey after 20% discount is: 250-50 = 200
Sale Price of jersey = $200
Now we add 5% GST
5% off 200
[tex]5\% \ of \ 200\\=\frac{5}{100}\times 200\\=10[/tex]
So, GST amount is $10
Total cost of jersey = Sale Price + GST
Total cost of jersey = $200+$210
Total cost of jersey = $210
Option A is correct option

Answer:
largest angle measures 108°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
8x - 6 + 108 + 14 = 180, simplify left side
8x + 116 = 180 ( subtract 116 from both sides )
8x = 64 ( divide both sides by 8 )
x = 8
Thus
∠ U = 8x - 6 = 8(8) - 6 = 64 - 6 = 58°
Then the largest angle measures 108° ( ∠ B )

Shaun loves to play golf. He wants to become a member at a golf course but is unsure which one
to choose. He has narrowed it down to two golf courses:
Red Crest has an annual membership fee of $650 and charges $20 per round of golf
Cardinal Golf Club charges an annual membership fee of $450 plus $25 per round of golf
Write an equation for the total charge of each golf course
Let y represent the total charge.
Let x represent the number of rounds of golf played during the season
Answer:
Equation: (650 + 20) < (450 + 25)Sentence to answer with: Cardinal Gold Club is the better golf couse because it is cheaper when we compare to total of both prices altogether.Step-by-step explanation:
The reason why this club is better is because in Red Crest the fee is 650 and the charges per round is 20 so we add 650 + 20 to get the total of 670. Now we have to find the total of the Cardinal Golf Club and to do that we have to add their fee of 450 + the charges for each round which is 25 and 450 + 25 equals to 475. Lastly we have to compare to find the less/cheaper one ehich is Cardinal.
