A truck delivers tables and chairs for a fair. The truck can carry 1000 pounds total.
-Tables weigh 50 pounds each
-Chairs weigh 10 pounds each
Use the above information to write an equations for the number of tables, t, and the number of chairs, c, that the truck can carry.
The required expression is given as 50t + 10c = 1000.
Given that,
A truck delivers tables and chairs for a fair. The truck can carry 1000 pounds in total.
-Tables weigh 50 pounds each
-Chairs weigh 10 pounds each
The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
Let the number of tables, t, and the number of chairs, c, that the truck can carry,
Now,
Total weight of T table = 50t
Total weight of c table = 10c
Total weight truck Carry = 1000
50t + 10c = 1000
Thus, the required expression is given as 50t + 10c = 1000.

5.20/65 x 100 = 8
PERIOD!!!
Answer:
8%
Step-by-step explanation:
$65.00 + 8% = 70.2
65 x (1 + 8%) = 65 x (1 + 0.08) = 70.2
How to do it:

The car can hold up to 4 passengers. Write an inequality for the number of passengers that could be in the car at any given time.
Answer:
The equation relating the number of cars to the number of passengers is p = 4n
Step-by-step explanation:
Given that certain type of car has room for 4 passengers
To find: write an equation relating the number of cars to the number of passengers
Let "n" be the number of cars
Let "p" be the number of passengers
From given information,
Car has room for 4 passengers. Therefore, we can frame,
number of passengers = 4 ( number of cars )
p = 4 (n)
p = 4n
Thus the equation relating the number of cars to the number of passengers is p = 4n

A row of lockers has a length of 72 inches and a width of 60 inches. Gabrielle made a scale drawing of the row of lockers using a scale of 1/2 centimeters = 6 inches.
Answer:
Length- 6 centimeters. Width- 5 centimeters
Step-by-step explanation:
Ok, so 1/2 centimeter = 6 inches
let’s first take the length witch is 72 inches and divide that by 6. Then, since it half a centimeter, divide in half.
72/6 = 12 12/2 = 6 centimeters
Next is the width. Now we the same thing as the length. Take 60 and divide by 6 then divide in half.
69/6 = 10. 10/2 = 5 centimeters
In summary, The scale drawing has length of 6 centimeters and a width of 5 centimeters.
I hope this helps. Your welcome!

Answer:
Image after the rotation would be X(2, 1) Y(0,-2) and Z(-2, 1)
Step-by-step explanation: 180 clockwise or counterclockwise formula is that (x,y) becomes (-x,-y). This means that the coordinates are inverted to positive or negative.
The image after the rotation would be X(2, 1) Y(0,-2) and Z(-2, 1) according to the graph below.
What is a Graph?This is defined as a pictorial representation of numbers or variables in an organized manner.
180 clockwise or counterclockwise means that (x,y) becomes (-x,-y). This means that the coordinates are inverted to positive or negative depending on their respective signs.
This therefore means X(−2, −1), Y(0, 2), and Z(2, −1) = X(2, 1) Y(0,-2) and Z(-2, 1) .

Step-by-step explanation:
Seth's father is thinking of buying his son a six-month movie pass for $25. With the pass, movies cost $2
each.
Write a linear equation to represent the total cost spent of Seth seeing movies for the next 6 months.
x = number of movies
y = total cost
========================================================
Explanation:
The starting cost is $25, which is the amount spent even if no movies are watched.
Since x is the number of movies, and each costs $2, this means Seth spends an extra 2x dollars more on top of the $25 already spent.
In total, the cost is 2x+25 which leads to y = 2x+25
This linear equation is in slope intercept form y = mx+b
m = 2 = slope
b = 25 = y intercept
(BRAINLIEST TO THE FIRST RIGHT ANSWER) Find the area of the entire figure.
Answer:
11 cm
Step-by-step explanation:
I could be wrong since I am a bit confused.
I think that the 2cm is referring to the area of the top part of the figure, and I was told the other measures are 3cm, 3cm, and 3cm.
With that knowledge, I will multiply 3cm by 3cm to get 9cm
9cm + 2cm = 11cm

What is the area of quadrilateral DYES?
Answer:
16.97
Step-by-step explanation:
you need to find the length of DY (the hypotenuse of one of the triangles), and to do that, you need to find the length of CY, so subtract AB (which is 1) from AY (which is 5) and you are left with 4. then use the Pythagorean theorem to solve for DY. [tex]1^{2}[/tex] + [tex]4^{2}[/tex] = [tex]17^{2}[/tex]. [tex]\sqrt{17}[/tex] = 4.12 (rounded to the nearest hundredth). The last step is to solve for area, or length times height. The quadrilateral has equal side lengths, so the equation is
4.12 × 4.12 which equals 16.97
