The cost of the hamburger and hot dog will be $10.4 and $7.25, respectively. Then the correct option is D.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
At the school carnival, the soccer team sold hamburgers and hot dogs. A person buying one hamburger and one hot dog will spend $17.65. The soccer team sold 22 hamburgers and 39 hot dogs and made $511.55.
Let x be the cost of hamburgers and y be the cost of hot dogs. Then the equation will be
x + y = 17.65 ...1
22x + 39y = 511.55 ...2
Solve the equations, then we have
22(17.65 - y) + 39y = 511.55
388.3 - 22y + 39y = 511.55
17y = 123.25
y = $7.25
Then the value of x will be
x + 7.25 = 17.65
x = 17.65 - 7.25
x = $10.40
The cost of the hamburger and hot dog will be $10.4 and $7.25, respectively. Then the correct option is D.

an initial fee of $50 and $13.25 per
month. The other has no initial fee
but charges $25.75 per month for
the same data package. After how
many months would Marsha have
paid the same amount for either

Answer:
2. Definition of supplementary angles
3. [tex]\angle 1 + \angle 2 = \angle 1 + \angle 3[/tex]
4. [tex]\angle 2 = \angle 3[/tex]
5. Definition of congruent angles
Step-by-step explanation:
Required
Fill in the gaps
1. Given
Supplementary angles: [tex]\angle 1[/tex] and [tex]\angle 2[/tex]
Supplementary angles: [tex]\angle 1[/tex] and [tex]\angle 3[/tex]
2. Supplementary angles add up to 180.
So:
[tex]\angle 1 + \angle 2 = 180[/tex]
[tex]\angle 1 + \angle 3 = 180[/tex]
3. Apply transitive property on (2)
[tex]\angle 1 + \angle 2 = 180[/tex] and [tex]\angle 1 + \angle 3 = 180[/tex], then
[tex]\angle 1 + \angle 2 = \angle 1 + \angle 3[/tex]
4. Subtract [tex]\angle 1[/tex] from both sides
[tex]\angle 1 - \angle 1 + \angle 2 = \angle 1 + \angle 3 - \angle 1[/tex]
[tex]\angle 1 - \angle 1 + \angle 2 = \angle 1 - \angle 1+ \angle 3[/tex]
[tex]\angle 2 = \angle 3[/tex]
This property is called the subtraction property
5. If [tex]\angle 2 = \angle 3[/tex],
Then [tex]\angle 2[/tex] and [tex]\angle 3[/tex] are congruent

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Hudson and 7 of his friends found a bag of pennies.
Total pennies= 320
So, Pennie get by each
=320 ÷ 8
= 40
Hence, Each person gets 40 pennies.

Answer:
m = 1/2
Step-by-step explanation:
To find the slope, all you have to do is find the rise and divide it by the run. Rise means how many units you move up or down from point to point. Run means how far left or right you move from point to point.
You can pick any two points on the line. Let's say I choose (10, 5) and (20, 10).
Let's look at the y coordinates first. You have 5 and 10. To get from 5 to 10, you have to go up 5 units. Your rise is 5. Let's look at the x coordinates now. To get from 10 to 20, you have to go up 10 units. Your run is 10.
As I said before, the slope is rise/run. In this case, we have 5/10, which can be simplified to 1/2. Your slope is 1/2.
Note that any two points on this would give you the same answer of 1/2 for this line. If I had picked (30, 15) and (70, 35), I would still get 1/2.

the ratio of the number of left-handed batters in a team to the number of right -handed batters was 5 : 8 there were 45 left-handed batters .
\
a) how many right-handed batters were there?
b) find the ratio of the number of left- handed batters to the total number of batters express youe=r answer in simplest form
Answer:
72 right handed batters.
Step-by-step explanation:
45/5=9
8*9=72
45:72=5:8
Hope this helps.
Answer:
a) 72 right-handed batters
b) 5:13
Step-by-step explanation:
This is the answer because:
1) For problem a, we can see that 5 x 9 = 45. In order to balance the ratio, we also have to mulitply the 8 with a 9:
8 x 9 = 72
Therefore, the answer is 72 right-handed batters.
2) For b, there are two ways to do it. Sine we know that there are 5 left-handed batters, we just add 5 + 8 = 13. Therefore, the simplest form of the ratio is 5:13. Another we can do it is by adding 45 + 72 = 117 (total batters). Then, 45 of them are left-handed batters which means the ratio is 45:117 = 5:13.
Therefore, the answer is 5:13.

do you guys mind helping me with this question
Answer:
4 and 6
Step-by-step explanation:
Judging by the table and how x = 1 and y = 2, you can estimate that y is twice as much as x.
This is supported by the equation, if you take 2 and multiply it by x (1) and take 3 and multiply it by y (2), then add the 2x1 (2) and 3x2 (6), you should get 8.

In ΔCDE, \text{m}\angle C = (5x+18)^{\circ}m∠C=(5x+18) ∘ , \text{m}\angle D = (3x+2)^{\circ}m∠D=(3x+2) ∘ , and \text{m}\angle E = (x+16)^{\circ}m∠E=(x+16) ∘ . Find \text{m}\angle D.M∠D.
Answer:
Angle D = m∠D= 50°
Step-by-step explanation:
In ΔCDE we are given: 3 angles
m∠C=(5x+18) ∘
m∠D=(3x+2) ∘
m∠E=(x+16) ∘ .
The sum of angles in a triangle = 180°
Hence:
m∠C + m∠D + m∠E = 180°
(5x+18)° + (3x+2)° + (x+16)° = 180°
5x + 18 + 3x + 2 + x + 16 = 180°
5x + 3x + x + 18 + 2 + 16 = 180°
9x +36= 180°
Subtract 36 from both sides
9x + 36 - 36 = 180° - 36°
9x = 144°
x = 144°/9
x = 16
From the above question, we are asked to find:angle D (m∠D )
Hence:
m∠D=(3x+2)°
m∠D=( 3 × 16 + 2)°
m∠D=(48 + 2)°
m∠D= 50°

Complete one inequality to support Roger's claim and one to show that he is incorrect.
PLSSSSSSSSS HELp
Answer: [tex]0.1x-0.25y<0[/tex]
Step-by-step explanation:
Let the two numbers be x and y
10% of the first number will be;
10% of x
[tex]=\frac{10}{100} of x[/tex]
[tex]=0.1x[/tex]
25% of the other number will be ;
25% of y
[tex]0.25y[/tex]
If 10% of the first number is less than 25% of the other number, this is expressed as;
[tex]0.1x<0.25y[/tex]
[tex]0.1x-0.25y<0[/tex]
Hence the required inequality is [tex]0.1x-0.25y<0[/tex]

were sold?
Plss step by steppp
Answer:
96 apple pies, 64 cherry pies, and 48 blueberry pies.
Step-by-step explanation:
6 + 4 + 3 = 13, and 208 / 13 = 16. Now multiply each number in the ratio by 16, so 6 x 16 = 96, 4 x 16 = 64, and 3 x 16 = 48. You can check your answer by adding all 3 numbers and making sure it adds up to 208. Hope that helps
