The expression representing the cost of food for one person is $x + $7.
For the expression that represents the cost of food for one person if two friends bought a $14 pizza, and each person bought their own drink at $2x (where x is the number of drinks).
To find the cost for one person, we start with the total cost expression $2x + $14. Since there are two friends, we divide this total cost by 2. The expression for the cost of food for one person is $x + $7. This represents the individual cost of one person's drink at $2x, divided by 2, plus half of the pizza cost, which is $14 divided by 2, resulting in $7.
How to solve ×+6y=13. 2×+y=15
Answer:
x, y = 7, 1
Step-by-step explanation:
x+6y=13 ............ (i)
2x+y=15 ........... (ii)
We will apply substitute method.
From equation (i), we can get,
x+6y=13
or, x = 13 - 6y .......... (iii)
Putting the value of x in equation (ii), we can get,
2x+y=15
or, 2 × (13 - 6y) + y = 15
or, 26 - 12 y + y = 15 [multiplying]
or, -11 y = 15 - 26 [Subtracting 26 from both the sides]
or, -11 y = -11
or, [(-11 y) ÷ (-11)] = [(-11) ÷ (-11)] [Dividing both the sides by -11]
or, y = 1
Therefore, the value of y = 1
Putting y = 1 in equation (iii), we get,
x = 13 - 6y
or, x = 13 - 6 × 1
or, x = 13 - 6
or, x = 7
Therefore, the value of x = 7.
Answer: x, y = 7, 1

4. Why does Miss Maudie only have two small cakes instead of three
small cakes for the children? *
O
A. She only likes two of the children.
O
B. She only purchased two cakes.
C. She cuts a slice from the big cake for Jem.
Answer:
B
Step-by-step explanation:
She only has two cakes because that's all she bought.
Final answer:
The provided text does not contain information about Miss Maudie or the distribution of cakes, leading to the inability to answer why only two small cakes were provided instead of three.
Explanation:
The question refers to a situation within a piece of literature where Miss Maudie provides only two small cakes to the children instead of three. According to the provided context, there is no explicit mention of Miss Maudie or the exact circumstance of the cake distribution in the passages. Moreover, the excerpts provided do not contain information about a character named Miss Maudie.
They discuss Miss Sydney and her interactions with street beggars and a candy vendor, as well as the narrator's mother's childhood experiences with poverty. Since the textual evidence does not support any conclusions about Miss Maudie and her cakes, I cannot confidently provide an answer to the question about why Miss Maudie only has two small cakes instead of three for the children.

What is the area of the figure?
Enter your answer in the box.
The area of the figure is 112 square inches.
Step-by-step explanation:
Step 1:
To calculate the value of the composite shape we first divide it into shapes that we know.
In this case, the composite shape consists of a triangle and a square attached below it.
If we can calculate the individual areas of the two shapes we should be able to calculate the area of the composite shape.
Step 2:
The triangle has a base length [tex]=10-6=4[/tex] inches and the height is [tex]16-10=6[/tex] inches.
The area of the triangle [tex]= \frac{1}{2} (b)(h) = \frac{1}{2} (4)(6) = 12.[/tex]
The area of the triangle is 12 square inches.
Step 3:
The area of a square is the square of its side length. The given square has a side length of 10 inches.
The area of the square [tex]= a^{2} = 10^{2} = 100.[/tex]
The area of the square is 100 square inches.
Step 4:
Now we calculate the area of the entire figure by adding the areas of the triangle and the square.
Area of the figure [tex]= 100 + 12 = 112.[/tex]
So the area of the figure is 112 square inches.

solve the system
-4x+8y=20
2x+2y=-30
Answer:
x = -13 and y = -4
Step-by-step explanation:
-4x + 8y = 20 ................... eqn 1
2x + 2y = -30 ................... eqn 2
Step 1: Multiply eqn 1 by 2 and eqn 2 by 4
(-4x + 8y = 20) × 2
(2x + 2y = -30) × 4
we will have
-8x + 16y = 40 ....................eqn 3
8x + 4y = - 120 .................. eqn 4
Step 2: Add eqn 3 and 4 together
20y = - 80
Step 3: divide all through by 20
y = -80/20
y = -4
Step 4: Substitute -4 for y in eqn 1
-4x + 8(-4) = 20
-4x - 32 = 20
-4x = 20 + 32
-4x = 52
Step 5: Divide both sides by -4
x = 52/-4
x = -13
Answer:
{x,y} = {-35/3,-10/3}
Step-by-step explanation:
-4x+8y=20;2x+2-30
System of Linear Equations entered :
[1] -4x + 8y = 20
[2] 2x + 2y = -30
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 2y = -2x - 30
[2] y = -x - 15
// Plug this in for variable y in equation [1]
[1] -4x + 8•(-x -15) = 20
[1] -12x = 140
// Solve equation [1] for the variable x
[1] 12x = - 140
[1] x = - 35/3
// By now we know this much :
x = -35/3
y = -x-15
// Use the x value to solve for y
y = -(-35/3)-15 = -10/3
Solution :
{x,y} = {-35/3,-10/3}
A circle passes through point (-2, -1) and its center is at (2, -1). Which equation represents the circle?
Answer:
[tex]\text{A)}\qquad (x-2)^2+(y+1)^2=16[/tex]
Step-by-step explanation:
The formula for a circle of radius r centered at (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
Both of the given points are on the line y=-1. The distance between them is the difference of their x-coordinates, 2 -(-2) = 4. So, the radius of the circle is 4 and the equation becomes ...
(x -2)^2 +(y -(-1))^2 = 4^2
(x -2)^2 +(y +1)^2 = 16 . . . . . . . . . matches choice A

A local hamburger shop sold a combined total of 518 hamburgers and cheeseburgers on Tuesday. There were 68 more cheeseburgers sold than hamburgers.
How many hamburgers were sold on Tuesday?
hamburgers
Final answer:
To find the number of hamburgers sold, we set x as the number of hamburgers and x + 68 as the number of cheeseburgers, given that the total sold was 518. The equation x + (x + 68) = 518 is solved to find that 225 hamburgers were sold.
Explanation:
To solve this problem, let's use algebra. Let x be the number of hamburgers, then the number of cheeseburgers would be x + 68 since there were 68 more cheeseburgers sold than hamburgers. Given that the total number of hamburgers and cheeseburgers sold is 518, we can set up the following equation:
x + (x + 68) = 518
Solving for x we get:
2x + 68 = 518
2x = 518 - 68
2x = 450
x = 225
So, the hamburger shop sold 225 hamburgers on Tuesday.

• (1) Which of the following are AP’s ? If they form an AP, find the common difference d and write 3 more terms.
• (a) 2,4,8,16……
• (b) -1.2, -3.2,-5.2,-7.2,…..
• ©2, 5/2 ,3, 7/2…..
• (d)-10,-6,-2.2, ……
Answer:
Option (b) -1.2, -3.2,-5.2,-7.2,….. is AP
The common difference = -2
3 more terms are ⇒ -9.2 , -11.2 , -13.2
Option (c) 2, 5/2 ,3, 7/2….. is AP
the common difference = 1/2
3 more terms are ⇒ 4 , 9/2 , 5
Step-by-step explanation:
AP ⇒ arithmetic progression is a sequence of numbers provide that the difference of any two successive members is a constant.
So, we will check the options:
• (a) 2,4,8,16……
The difference between 2 , 4 = 4 - 2 = 2
The difference between 4 , 8 = 8 - 4 = 4
So, option a is not AP
• (b) -1.2, -3.2,-5.2,-7.2,…..
The difference between -1.2 , -3.2 = -3.2 - (-1.2) = -3.2 + 1.2 = -2
The difference between -3.2 , -5.2 = -5.2 - (-3.2) = -5.2 + 3.2 = -2
So, option b is AP
The common difference = -2
3 more terms are ⇒ -9.2 , -11.2 , -13.2
• (c) 2, 5/2 ,3, 7/2…..
The difference between 2 , 5/2 = 5/2 - 2 = 1/2
The difference between 5/2 , 3 = 3 - 5/2 = 1/2
So, option c is AP
The common difference = 1/2
3 more terms are ⇒ 4 , 9/2 , 5
• (d) -10,-6,-2.2, ……
The difference between -10 , -6 = -6 - (-10) = -6+10 = 4
The difference between -6 , -2.2 = -2.2 - (-6) = -2.2 + 6 = 3.8
So, option d is not AP
So, the options that form an AP are b and c

A group of 10 people is choosing a chairperson and vice-chairperson. They put all 10 people's names into a hat. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and vice-chair are there?
a.19
b.90
c.100
d.10! (10 factorial)
Answer:
B.90
Step-by-step explanation:
As there are 10 people and choosing chairperson occurs first as an independent event
=> The number of possible chairperson is 10.
After the chairperson is chosen, the number of names left in the hat is 9
=> There are 9 possible vice-chair.
However, the names left in the hat depends on which name is elected as chairperson
=> Choosing vice-chair is a an event dependent on the first event.
=> The number of possible combinations of chair and vice chair would be:
9x10 = 90
None of this makes sense

Answer:
-10, -8, -6, -4
Step-by-step explanation:
Perhaps you want to know what they are.
__
The odd number between the middle two is their average value: -28/4 = -7.
The integers are -10, -8, -6, -4.
Answer: The even integers are -10, -8, -6 and -4
Step-by-step explanation:
Let the smallest of the even integers be represented by x, the other three will therefore be x +2, x +4 and x+6
Thus, x + (x+2) + (x+4) + (x+6) = -28
4x + 12= -28
Make x the subject of the equation
4x= -28 - 12
4x= -40
x = -10,
since the x = -10,
x + 2= -10 + 2= -8
x + 4= -10 +4 = -6
x + 6= -10 + 6= -4
I hope this helps.
Find x please:
6x degrees + 5 degrees = 149 degrees
(6x+5)=149
Answer:
x = 24
Step-by-step explanation:
(6x + 5) = 149
6x + 5 = 149
6x = 149 - 5
6x = 144
x = 144 / 6
x = 24
Answer:
x=24
Step-by-step explanation:
This is a linear equation.
(6x+5)=149
Collect like terms by placing the +5 after the equality sign, which will make it become -5
6x=149-5
6x=144
Divide both sides by 6
6x/6=144/6
x=144/6
x=24
We can go further to check, if we are correct by substituting x with 24 in the equation. And then both sides of the equation must be the same
(6x+5)=149
6(24)+5=149
144+5=149
149=149

Answer:
Angle QPU = 110
Step-by-step explanation:
Since angle QPU & RPQ are supplementary angles, they add up to 180 degrees. So take 180 - 70 which gives you 110.
Answer:
Step-by-step explanation:
Note, line UPR is a straight line
Also, angle on a straight line is 180
Therefore,
<QPU and <QPR are supplementary
<QPU+<QPR=180
Given that <QPR=70°
<QPU+70=180
Subtract 70° from both sides of the equation
<QPU=180 -70
<QPU=110
Given: 2x + 3y = 6. When x has a value of zero, the y value is 2.
The statement is true. When x has a value of zero, the y value is 2. So option (a) is correct.
To determine whether the statement is true or false, let's first analyze the given equation:
2x + 3y = 6
We're given that when x = 0, y = 2. We can use this information to solve for y:
2(0) + 3y = 6
0 + 3y = 6
3y = 6
y = 6/3
y = 2
This confirms that when x = 0, y does indeed equal 2. So, the given information is consistent with the equation. Therefore, the statement "When x has a value of zero, the y value is 2" is true.
To summarize:
Given the equation 2x + 3y = 6, when x = 0, y = 2.
Proof:
2(0) + 3(2) = 6
0 + 6 = 6
6 = 6
Thus, when x is 0, y is indeed 2, verifying the statement as true.
Complete Question:
Given: 2x+3y=6. When x has a value of zero, the y value is 2.
(a) True
(b) False
