Answer:
5 1/2
Step-by-step explanation:
add -2 and 7 bc negative and negative makes positive making it 5
then add 1/6 and 1/3 but they have to have the same denominator so u multiply 2 to 1/3 which makes it 2/6 and 2/6 + 1/6= 3/6 which simplify to 1/2
Answer: 5 1/6
Step-by-step explanation:
-2 1/6 we can write as - 13/6
-7 1/3 we can write as - 22/3
lets get the common denominator, which is 6
-13/6+44/6= 31/6= 5 1/6

Tickets to a rock concert cost $32.50 each. The school choir bought 54 tickets for the Saturday concert and 33 tickets for the Sunday concert. How much did the choir pay in all for the tickets?
Answer:
$2827.5
Step-by-step explanation:
Cost of each ticket = $32.50
The school choir bought 54 tickets for the Saturday concert and 33 tickets for the Sunday concert.
Cost for Saturday concert = 32.50 × 54
= $1755
Cost for sunday concert = 32.50 × 33
= $1072.5
Total cost = Cost for Saturday concert + Cost for Sunday concert
= $1755 + $1072.5
= $2827.5
Hence, he will pay $2827.5 in all for the tickets.

When Aiden left his house in the morning, his cell phone battery was partially charged. The charge remaining in Aiden's battery, as a percentage, can be modeled by the equation B = -2t + 26, where t is the number of hours since Aiden left his house. What is the slope of the equation and what is its interpretation in the context of the problem?
Answer:
The slope is -2
It means that the battery decreases by 2% each hour since Aiden left his house
Step-by-step explanation:
In the equation y = mx + b, m is the slope.
This equation's slope is -2, since it is the coefficient for t.
In the context of this problem, this means that the battery will decrease by 2% each hour since Aiden has left his house.

What is the zero of function f?
A. x= 1
B. x= -3
C. x= 9
D. x= -1
The zero of the given function f(x) is x = 1. The correct answer is an option (A).
To find the zero of the function f(x) = 3√(x + 3) - 6, we set the function equal to zero and solve for x:
3√(x + 3) - 6 = 0
Adding 6 to both sides:
3√(x + 3) = 6
Dividing both sides by 3:
√(x + 3) = 2
Squaring both sides to eliminate the square root:
x + 3 = 4
Subtracting 3 from both sides:
x = 1
Therefore, the zero of the function f(x) is x = 1.
Thus, the correct answer is A.

Coupon A:
Coupon B:
$40 rebate on a $83 phone
45% off of a $83 phone
Choose the coupon that gives the lower price.
Then fill in the blank with the correct value.
Coupon A gives the lower price.
The price with coupon A is $
$] less than the price with coupon B.
Coupon B gives the lower price.
The price with coupon B is $] less than the price with coupon A.
Answer:
A= 45% off $85 is $45.65, which is a $37.35 price difference on the item.
B= simple you are taking 40 dollars off the price, so it's $43 for the 83 dollar phone.
The correct answer is B.
The Coupon A gives a lower price, The price with coupon A is $2.65 less than the price with coupon B.
What is a percentage?The percentage is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one-hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
Given:
Coupon A: $40 rebate on a $83 phone and Coupon B: 45% off of a $83 phone,
Calculate the prize after applying Coupon A as shown below,
The prizes after applying Coupon A = 83 - 40
The prizes after applying Coupon A = 43
Calculate the prize after applying Coupon B as shown below,
The prizes after applying Coupon B = 83 - 45% of 83
The prizes after applying Coupon B = 83 - 37.35
The prizes after applying Coupon B = 45.65
Thus, Coupon A gives a lower price.

Sandra has a $20 itunes gift card and spends $3 each month. Which equation can be
used to find how much money Sandra has on her giftcard after x months?
Answer:
y=20-3x
Step-by-step explanation:
The equation that can be used will be y = 20 - 3x
Amount of gift card that Sandra has = $20
Amount spent each month = $3
Let the remaining amount be represented by y
Therefore, the amount that will remain after x months will be deducted from the original amount that she has which will be:
y = 20 - (3 × x)
y = 20 - 3x

x²-4x+3=0, then what is the value of (x-2)²=?
Answer:
We conclude that:
[tex]\left(x-2\right)^2=1[/tex]
Step-by-step explanation:
Given the expression
[tex]x^2-4x+3=0[/tex]
subtract 3 from both sides
[tex]x^2-4x+3-3=0-3[/tex]
[tex]x^2-4x=-3[/tex]
Add -2² to both sides
[tex]x^2-4x+\left(-2\right)^2=-3+\left(-2\right)^2[/tex]
simplify
[tex]x^2-4x+\left(-2\right)^2=1[/tex]
Applying the perfect square formula: (a-b)² = a²-2ab+b²
so
[tex]\left(x-2\right)^2=1[/tex] ∵ [tex]x^2-4x+\left(-2\right)^2=\left(x-2\right)^2[/tex]
Therefore, we conclude that:
[tex]\left(x-2\right)^2=1[/tex]
Enter the equation of the line which passes through the points (0,−3) and (2, 1)
Answer:
y = 2x -3
Step-by-step explanation:
The formula for the equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept of the line. I will be calculating the slope of the line using the points (0, 3) and (2, 1)
Slope = [tex]\frac{rise}{run}[/tex]
= [tex]\frac{1-(-3)}{2-0}[/tex]
= [tex]\frac{1+3}{2-0}[/tex]
= [tex]\frac{4}{2}[/tex]
= 2
The y-intercept is the point on the y-axis when the point on the x-axis is 0. Based on the point (0, -3), you can see that the point on the y-axis, while the point on the x-axis is 0, is -3. Thus, the y-intercept is (-3).
Overall, the equation of the line is: y = 2x-3
20% of the time Tucker eats out twice a month, 30% of the time he eats out once a month, and 50% of the time he doesn't eat out at all in a given month. What is the expected value for the number of times Tucker eats out during a month?
Answer:
0.7
Step-by-step explanation:
Given that :
20% of the time Tucker eats out twice a month, 30% of the time he eats out once a month, and 50% of the time he doesn't eat out at all in a given month.
THIS CAN be expressed in terms of probability distribution thus :
X : _____ 2 _____ 1 _______0
P(X) : __ 0.2 ____ 0.3 ____ 0.5
Hence, expected value for the number of times Tucker eats out during a month
E(x) = Σ(X)*p(x)
E(x) = (2 * 0.2) + (1 * 0.3) + (0 * 0.5)
E(x) = 0.4 + 0.3 + 0
E(x) = 0.7

Answer:
D
Step-by-step explanation:
imagen the inequality sign is a normal equal sign so you would just do it as a normal problem solving for the variable.
so first get n by its self so you start by gettting rid of 8.7, so to cancle it out you minus it by its self and what you do to one side you do to the other.
now you have -2.5n > -3.25
divide it by its self by both sides and you get 1.3
and because you divided by a negative your sign switches to the other side. It’s called the negative division rule

Answers to choose from:
A 22 5/6 square feet
B 120 1/6 square feet
C 120 1/3 square feet
D 129 1/6 square feet
Answer:
D. 129 1/6 square feet
Step-by-step explanation:
L x W = A is the equation used to solve for the area of quadrilaterals
When we substitute the values of L and W for what the length and width actually are, we end up with the equation 12 1/2 x 10 1/3 = A.
Now you just need to multiply the length and width which will give you 129 1/6 square feet.

The sum of three numbers is 26. The second number is twice the first and the third number is 6 more than the second. Find the numbers.
Answer:
The numbers are 4, 8 and 14
Step-by-step explanation:
Required
Determine the three numbers
We start by declaring the variables
Let the three numbers be [tex]x,\ y\ and\ z\ respectively[/tex]
Next, we write the relationships between the numbers
[tex]y = 2 * x[/tex] --- Second = Twice the first
[tex]z = 6 + y[/tex] --- Third = 6 more than second
[tex]x + y + z = 26[/tex] --- Sum of the three numbers
Then, we solve for each number
[tex]y = 2 * x[/tex]
[tex]z = 6 + y[/tex]
[tex]x + y + z = 26[/tex]
Substitute 6 + y for x in [tex]x + y + z = 26[/tex]
[tex]x + y + 6 + y =26[/tex]
Collect Like Terms
[tex]x + y + y = 26 - 6[/tex]
[tex]x + 2y = 20[/tex]
Substitute 2 * x for y in [tex]x + 2y = 20[/tex]
[tex]x + 2(2*x) = 20[/tex]
[tex]x + 4*x = 20[/tex]
[tex]x + 4x = 20[/tex]
[tex]5x = 20[/tex]
Solve for x
[tex]x = \frac{20}{5}[/tex]
[tex]x = 4[/tex]
Recall that:
[tex]y = 2 * x[/tex]
[tex]y = 2 * 4[/tex]
[tex]y = 8[/tex]
Recall that:
[tex]z = 6 + y[/tex]
[tex]z = 6 + 8[/tex]
[tex]z = 14[/tex]
Hence, the numbers are 4, 8 and 14
To test the result:
[tex]x + y + z = 26[/tex]
[tex]4 + 8 + 14 = 26[/tex]
[tex]26= 26[/tex]
