First, we need to set up an equation.
6x + 8.75 = 40.55
Then, we use the equation to solve for how much a pound of BBQ costs.
To move 8.75 to the other side, we have to subtract 8.75 from both sides of the equation.
6x = 40.55 - 8.75
6x = 31.8
Next, we divide both sides by 6 to get the value of x.
6x/6 = x
31.8/6 = 5.3
Lastly, add the correct unit.
$5.3.
Therefore, the price per pound of BBQ is $5.30

Answer:
25%
Step-by-step explanation:
John went to the bakery and bought
several dozen donuts and several
dozen bagels. The donuts cost $9
per dozen and the bagels were $8
per dozen. If he spent a total of
$101 for 12 dozen items, how many
donuts did he buy?
Answer:
5 dozen Donuts
7 dozen bagels
Step-by-step explanation:
5 * 9 = 45
7 * 8 = 56
56 + 45 = 101
Answer: He bought 5 dozen donuts
Step-by-step explanation:
d + b = 12 where d is the number of donuts and b is the number of bagels.
9d + 8b= 101 now solve the two equations using the elimination method
-9d - 9b =-108
9d + 8b = 101
-1b = -7
b = 7
9d + 8(7)= 101
9d + 57 = 101
9d = 45
d= 5

Solve the following: 3r+18=6+5r What is 'r' equal to?
Answer:
r = 6
Step-by-step explanation:
The equation is 3r + 18=6 + 5r. First, you have to get the coefficient on one side because it will be easier to solve. In order to do so, I subtract 3r from both sides. The equation is now 18=6 + 2r. The next step is to get the constant which is 6 to the left side. You subtract 6 from both sides. You are left with 12=2r. All you have to do now is to get r alone. In order to do that you have to divide both sides by 2. The answer would be 6. Hope you find this helpful!

The three angles of a triangle form an A.P. If the largest angle is twice than the smallest angle find theee angles of that triangle
Answer:
Let the angles be (a-d), a , (a+d)
a-d + a + a + d = 180 (angle sum property)
3a = 180
a = 60
Given:
a+d = 2(a-d)
60 + d = 2(60 - d)
60 + d = 120 - 2d
3d = 120 - 60
d = 20
Angles are : 40 , 60 , 80

Use a ratio box to solve this problem. The cost of a 10-minute call to Boise decreased by 20%. If the cost before the decrease was $3.40, what was the cost after the decrease?
Answer:
$2.72
Step-by-step explanation:
If the price decreased by 20%, the final price will be 100% - 20% = 80% of the inicial price.
So, we can write the ratio box:
Old value New value
Percent value: 100% 80%
Value: $3.40 X
Then we can solve with a rule of three:
100% -> $3.40
80% -> X
X = 0.8 * 3.4 = $2.72
Answer:
The cost after the 20% decrease is $2.72
Step-by-step explanation:
Here, we are trying to calculate the cost of a 10-minute call before there was a decrease in the amount charged for the call.
We proceed mathematically as follows,
To calculate percentage decrease, we can employ the formula;
(old value- new value)/old value * 100%
Here our old value or cost was $3.40 and the percentage decrease is 20%
we plug these values;
Let the new cost it value be x
(3.4-x)/3.4 * 100 = 20
100(3.4-x) = 20 * 3.4
340 - 100x = 68
100x = 340 -68
100x = 272
x = 272/100
x = $2.72
I am thinking of a positive integer that is 3 less than 3 times another number. The product
of my number and Ihe other number is 90. What is my number?
Answer:
15
Step-by-step explanation:
Write an equation expressing the given relationship. Solve it to find the numbers.
__
setupLet x represent "another number." Then the number I'm thinking of is ...
(3x -3)
and the product of that and "the other number" is 90:
x(3x -3) = 90
solutionx(x -1) = 30 . . . . . . divide by 3
We know the factors of 30 are ...
30 = 30·1 = 15·2 = 10·3 = 6·5
Of these factor pairs, the numbers that differ by 1 are 6 and 5. "The other number" is 6, and "my number" is 90/6 = 15.
My number is 15.

Answer:
(32, 16)
Step-by-step explanation:
Since the scale factor is 4, you always multiply both coordinate places (x and y) by this number.
The coordinates of one of the new vertices is (32, 16). Therefore, option D is the correct answer.
What is a dilation?Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.
Given that, rectangle with vertices A(-6, 4), B(8, 4), C(8, -2) and D(-6, -2).
Here, the scale factor is 4
So,
(-6,4) by a scale factor of 4(-6, 4)=(-24, 16)
(8, 4) by a scale factor of 4(8, 4)= (32, 16)
(-6, -2) by a scale factor of 4(-6, -2)= (-24, -8)
(8, -2) by a scale factor of 4(8, -2)= (32, -8)
Therefore, option D is the correct answer.

Your friend can eat a lot! Cheeseburgers from In-N-Out are his favorite, so he gets happy
when he eats them, that is, until he eats too many! If you measured his happiness, h(x),
based on how many cheeseburgers from In-N-Out he eats, x, you would get a curve modeled
by the function: ℎ() = −12 + 6 + 16....................................................................
Answer:
There are needed 3 burgers to reach the maximum measure of happiness of 25.Step-by-step explanation:
The given function is
[tex]h(x)=-x^{2} +6x+16[/tex]
Where [tex]x[/tex] is the number of burgers and [tex]h[/tex] the measure of happiness.
To find the maximum burgers needed to reach the maximum happiness, we just need to find the vertex of this function, which is defined as
[tex]V(h,k)[/tex] where [tex]h=-\frac{b}{2a}[/tex], and [tex]b=6[/tex], [tex]a=-1[/tex], replacing these values, we have
[tex]h=-\frac{6}{2(-1)}=3[/tex]
[tex]k=f(3)=-(3)^{2} +6(3)+16=-9+18+16=25[/tex]
Therefore, there are needed 3 burgers to reach the maximum measure of happiness of 25.
Using the maximum function relation, the maximum number of cheeseburgers to be consumed would be 25
Given the function :
h(x) = - x² + 6x + 16The function is maximum at [tex] \frac-{b}{2a}[/tex]
b = 6 ; a = - 1
Hence, we have :
[tex] x = \frac-{6}{2(-1)} = 3 [/tex]
Substitute x = - 3 into the function :
h(-3) = - (3)² + 6(3) + 16
h = - 9 + 18 + 16
h = 25
Therefore, the maximum number of cheeseburgers to be tanken would be 25

Emma substitutes 3 for x in a one-variable linear equation and finds that it makes the equation true. She then substitutes 5 for x then in the same linear equation true. What can you conclude about the number of solutions of the equation
Answer:
The equation has infinite solutions
Step-by-step explanation:
Linear equations can have zero, one or infinite solutions.
If Emma tested two values (3 and 5) for the same equation and they were both true solutions, this means that the equation has more than one solution.
If a linear equation has more than one solution, than the equation has infinite solutions.

6 times a number is 27 less than the square of that number. Find the
positive solution.
Answer:
x = 9
Step-by-step explanation:
To solve these problems, you first set up an equation representing the information given.
6x = x² - 27
This turns into a quadratic equation which you need to factor out.
0 = x² - 6x - 27
You want to choose two numbers that multiply to -27, and add up to -6
0 = (x - 9)(x + 3)
If you're unfamiliar with factoring, you take the opposite sign of the number in the parentheses because it's a shortcut when setting it equal to 0.
x = 9, -3
Since it asks for the positive solution only, the answer is x = 9.

Answer:
C) (negative 1, one-half), (0, 1), (1, 2), (2, 4)Step-by-step explanation:
The set C could be generated by an exponential function. The main reason is that exponential functions hava a restricted range, it can't have negative numbers or the number zero, because power can only be equal or greater than 1.
Additionally, for all exponentials, a null exponent gives 1 as an answer, so point (0, 1) is always present in an exponential function.
Therefore, the right answer is C.
The set of ordered pairs could be generated by an exponential function is C. (negative 1, one-half), (0, 1), (1, 2), (2, 4)

If the legs of an isosceles right triangle have a length of 15 StartRoot 2 EndRoot ft, what is the length of the hypotenuse? 7.5 feet feet feet 30 feet
Answer:
The length of the hypotenuse is 30 feet
Step-by-step explanation:
Here, we are to calculate the length of the hypotenuse of an iscosceles right triangle.
For the triangle to be isosceles, it means that the opposite and the adjacent are equal in length.
Now, to calculate the value of the hypotenuse, we make use of the Pythagoras’ theorem which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Mathematically;
let’s say the hypotenuse is length h feet
h^2 = {15√(2)}^2 + {15√(2)}^2
h^2 = (225 * 2) + (225 * 2)
h^2 = 450 + 450
