Answer:
Cost of 1 hamburger = $1.3
Step-by-step explanation:
Assume;
Cost of 1 hamburger = a
Cost of 1 French fries = b
On first trip
3a + 4b = 7.10......eq1
On second trip
2a + b = 3.40....eq2
From eq2 x 4
8a + 4b = 13.6....eq3
From eq3 - eq1
5a = 6.5
a = 1.3
Cost of 1 hamburger = $1.3
The cost of a hamburger and an order of French pies is $1.3 and $0.8 respectively.
let
cost of hamburger = x
cost of French pies = y
The equation:
3x + 4y = 7.10 (1)
3x + 4y = 7.10 (1)2x + y = 3.40 (2)
multiply (2) by 4
8x + 4y = 13.6 (3)
3x + 4y = 7.10 (1)
subtract (3) from (1)
8x - 3x = 13.6 - 7.10
5x = 6.5
x = 6.5 / 5
x = 1.3
substitute x = 1.3 into (2)
2x + y = 3.40 (2)
2(1.3) + y = 3.40
2.6 + y = 3.40
y = 3.40 - 2.6
y = 0.8
Therefore, cost of a hamburger and an order of French pies is $1.3 and $0.8 respectively.

We know that [tex]xy = 36[/tex]
There are infinity values for [tex]x, y[/tex], but considering [tex]x, y \in \mathbb{Z}[/tex]
Below we have all the solutions for [tex]x, y[/tex]
Negative:
[tex]\\x = -36 \text{ and } y = -1\\x = -18 \text{ and } y = -2\\x = -12 \text{ and } y = -3\\x = -9 \text{ and } y = -4\\x = -6 \text{ and } y = -6\\x = -4 \text{ and } y = -9\\x = -3 \text{ and } y = -12\\x = -2 \text{ and } y = -18\\x = -1 \text{ and } y = -36\\[/tex]
Positives:
[tex]x = 36 \text{ and } y = 1\\x = 18 \text{ and } y = 2\\x = 12 \text{ and } y = 3\\x = 9 \text{ and } y = 4\\x = 6 \text{ and } y = 6\\x = 4 \text{ and } y = 9\\x = 3 \text{ and } y = 12\\x = 2 \text{ and } y = 18\\x = 1 \text{ and } y = 36\\[/tex]

Simplify FULLY 6:1.2 *
Answer:
after full simplification u will get your ratio as
5:1
The fully simplified form of the ratio 6:1.2 is 5:1.
To simplify the ratio 6:1.2, we can divide both parts of the ratio by their greatest common divisor (GCD) to obtain the simplest form.
First, let's determine the GCD of 6 and 1.2. The GCD of 6 and 1.2 is 0.6 since 0.6 is the largest number that divides both 6 and 1.2 evenly.
Next, divide both parts of the ratio by 0.6:
6 ÷ 0.6 = 10
1.2 ÷ 0.6 = 2
Thus, the simplified ratio is 10:2.
However, we can further simplify the ratio by dividing both parts by their GCD, which is 2:
10 ÷ 2 = 5
2 ÷ 2 = 1
Therefore, the fully simplified form of the ratio 6:1.2 is 5:1.
This means that for every 5 units of the first quantity, there is 1 unit of the second quantity. Simplifying ratios allows for easier comparison and interpretation of the relationship between the two quantities.

Number of Miles
Answer:
C.)Yes, because the pictures do not accurately represent the proportions of the distances for each leg of the triathlon.
No, because the height of each column corresponds to the number of miles for each leg of the triathlon. Then the correct option is A.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Can someone tell me how to find ratios and what they are please!? Don't use the web!
Answer:
Step-by-step explanation:
Suppose you are standing on a street corner. Suppose that you are counting cars. You notice that there are only black ones and white ones. For every 3 black cars there are 4 white ones. Beginning ratios always look something like this.
Black to white = 3 to 4
This is more commonly written in two ways
Black to White = 3/4 Black:White:: 3:4So what do you notice? You should see that a ratio is a fraction.
All ratios are fractions.
Now suppose you are still on the street counting cars again. Suppose you notice that after counting 70 cars, you get
Black to White = 30:40Is that still 3/4? The answer is yes. You can multiply 3/4 by the same number on the top as you did on the bottom.That's as much as I want to give you at this time.

twice the number of cats. Write a system of
equations to model this.
°{
oſ d+c= 12
Id=2e - 3
os d+c= 12
2c = d - 3
Osd+c= 12
1 c = 2d - 3
of d+c = 12
Id=3- 26
Answer:
d + c = 12
d = 2c - 3
Step-by-step explanation:
Given that :
Total number of dogs and cats = 12
Let :
Dogs = d ; Cats = c
d + c = 12
Number of dogs = 2 times the number of cats less than 3 ;
Mathematically,
d = 2c - 3
The system of equations to model the situations are,
d + c = 12 and d = 2c - 3.
What is System of Equations?System of equations are a set of two or more equations which has to be solved together, which means the solution we get after solving these equations must be satisfying for all the equations given.
System of equations will get a unique solution if the number of variables in the equation is equal to the number of equations in the system.
Let 'c' denote the number of cats and 'd' denote the number of dogs.
Total number of dogs and cats = 12
That is, d + c = 12
Number of dogs is 3 less than twice the number of cats.
So, d = 2c - 3
Hence the system of equations to model the given statements is,
d + c = 12
d = 2c - 3

Given g(x) = 2x + 4, solve for x when g(x) = -8
Answer:
The value of x = -6
Step-by-step explanation:
Step(i):-
Given that g(x) = 2 x + 4 and g (x ) = -8
⇒ Equating
2 x +4 = - 8
Subtracting '4' on both sides, we get
2 x + 4 - 4 = -8 -4
⇒ 2 x + 0 = -12
⇒ 2 x = -12
Step(ii):-
Dividing '2' on both sides, we get
x = -6
The value of x = -6
