Let's assume –
Number of two-seat tables be "x"[tex]\qquad[/tex] According to the question :-
[tex]\qquad \pmb{\sf\longrightarrow 4 \times (28−x)+2 \times x=90}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow 112−4x+2x=90}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow 112−2x=90}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow −2x=90−112}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow −2x=−22}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow 2 x=22}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow x= \cancel{\dfrac{22}{2}}}[/tex]
[tex]\qquad \longrightarrow {\pink{\underline{\underline{\pmb{\sf{ x= 11}}}}}}[/tex]
Therefore –
Number of two-seat tables are 11.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Answer: 11
Step-by-step explanation:
This is a problem of solving word problems using systems of equations.
Let's denote 2-seat tables by x and 4-seat tables by y. Therefore, their sum will be the total number of tables, which is 28. So, x + y = 28.
Now, let's concentrate on the number of customers. It says that 'when all tables are full, there will be 90 customers in the restaurant'. Therefore if we seat 2 people on each 2-seat table(x), their total number will be 2x and if we seat 4 people on each 4-seat number(y), their total number will be 4y. Hence, 2x + 3y = 90.
Now, we have a system with two equations:
[tex]\left \{ {{x + y = 28} \atop {2x + 4y = 90}} \right.[/tex]
Multiply the first line by -4.
[tex]\left \{ {{-4x -4y = -112} \atop {2x + 4y = 90}} \right.[/tex]
Now, by adding up these two equations, we get the following:
-2x = -22
x = 11
This means that the restaurant has 11 two-seat tables.

please help me? im not understanding this question at all.
Answer:
well it looks like as each week is going by the puppy is gaining less weight cause at first 5 is added and then 4 so maybe the next week 3 is added
Answer:
Yes, the relationship is proportional.
Step-by-step explanation:
So if you don't understand what proportional means, it means corresponding, the same, equal.
So when you look at a graph like this then ask yourself this, "is x a multiple of y?"
For example: Is 2 a multiple of 4? Yes! It is! That makes it proportional.
Is 3 a multiple of 9? Yes it is! 3, 6, 9.
Is 4 a multiple of 12? It is 4, 8, 12

What scale factor would increase the
size of the rectangle so that it has an
area of 96 cm??
2cm
3cm
Answer:
4
Step-by-step explanation:
If you increase the scale factor by 4, the sides become:
L= 2×4 = 8
W= 3×4 = 12
Now to find the new area:
8 × 12 = 96cm^2
So, a scale factor of 4 would give the rectangle a scale factor of 96.
Hope this helps and have a nice day!

Name the scale of the number line shown.
The scale of the given line will be 4 which is the difference in the length between the two successive numbers.
What is Number Line?In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.
The number line is given in the question.
The scale of the number line is the difference in the length between the two successive numbers.
According to the given number line,
Here numbers are 9, 13, 17, 21, 25, 29
So the difference in the length between the two successive numbers
⇒ 13 - 9 = 17 - 13 = 21 - 17 = 25 -21 = 29 - 25 = 4
Therefore, the scale of the given line will be 4.

A high school teacher teaches three classes per day. Her first class has double the number of students as her second class, while her third class has 13 more students than her second class. In total, she teaches 53 students. The equation 2x + x + (x +13) = 53 represents this scenario, where x is the number of students
in her second class.
How many students are in her second class?
Answer: 10
Step-by-step explanation: first subtract 13 from 53 which gives you 40 then divide 40 by 4 which gives you 10 but because your first class is double more than your second class it has 20 students and your second class has 10 students and because you have to add that 13 back in your third class has 23 students

write an equation that passes through (2,4) is parallel to the line 3x-2y=-10
Answer:
y = 3x/2 + 3
Step-by-step explanation:
First let's solve for y in the given equation
Subtract 3x from both sides
3x - 2y = -10
- 3x - 3x
-2y = -3x - 10
Divde both sides by -2
-2y/-2 = (-3x - 10)/-2
y = 3x/2 + 5
The slop of the parallel equation will have to be 3/2
y = 3x/2 + b
Plug in the given coordinates
4 = 3(2)/2 + b
4 = 1 + b
Subtract 1 from both sides
4 = 1 + b
- 1. - 1
b = 3
y = 3x/2 + 3
Please find the equation of the quadratic
Answer:
y = 4(x - 3)² - 5
Step-by-step explanation:
Given the vertex, (3, -5), and the other point, (4, -1):
Substitute these values into the vertex form of the quadratic equation:
y = a(x - h)² + k
where:
(h, k) = vertex
a = determines the direction of which the graph opens (if a > 1, the graph opens up; a < 1, the graph opens down). The value of a also determines the width of the parabola. If 0 < a < 1, the graph will be wide; if a > 1, the graph will be narrow.
h = indicates a horizontal translation.
k = indicates a vertical translation.
Next, substitute the values of the vertex, (3, -5), and the other given point, (4, -1) into the vertex form and solve for the value of a:
y = a(x - h)² + k
-1 = a(4 - 3)² - 5
-1 = a( 1 )² - 5
-1 + 5 = a1 - 5 + 5
4 = a
Therefore, the equation of the given graph is: y = 4(x - 3)² - 5.
Note:
If the equation needs to be in standard form, ax² + bx + c, simply expand the binomial factors in the vertex form, and combine like terms. Doing so will result in the following standard form: y = 4x² - 24x + 31.
