A chair rental company charges $100 for delivery plus $3 per chair.
You have $410 to spend on chairs. How many can you rent?
Answers
Answer:
103 chairs
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
410 = 100 + 3*c
Subtract 100 from each side
410-100 = 100+3c-100
310 = 3c
Divide by 3
310/3 = 3c/3
103.3=c
We cannot rent part of a chair so we round down

B (7, 12)
C (-5, 4)
D(-5, -12)
Answers
Answer:
A(7,4)
Step-by-step explanation:
-2/3 is the slope and the slope is the rise over the run, and we know it passes through the point (1,8).
Next, we can create a chart/table

Find the speed of the train if the the train travels 360 miles in 4 hours.
Answers
Answer:
90 mph
Step-by-step explanation:
To get miles per hour ([tex]m/h[/tex]), we just need to divide. [tex]360/4[/tex] gives us [tex]90/1[/tex], meaning the train travelled 90 miles in one hour. This is the same as going 90 mph. Hope that explained things :)
It takes 6 kg of wheat to obtain 8 kg of flour and 12 kg of flour to obtain 9 kg of bread.
How much wheat do you need to make 84 kg of bread?
Answers
Answer:
56 kg of wheat.
Step-by-step explanation:
84 kg of bread is 9 1/3 greater than 9 kg of bread meaning we can multiply the ingredients by 9 1/3 to find the amount of wheat needed to make 84 kg of bread.
6 kg of wheat · 9 1/3 = 56 kg of wheat
Write an equation for the nth term of the arithmetic sequence. -6,-9,-12,-15
Answers
Answer:
[tex]a_{n}[/tex] = - 3n - 3
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 6 and d = a₂ - a₁ = - 9 - (- 6) = - 9 + 6 = - 3 , then
[tex]a_{n}[/tex] = - 6 - 3(n - 1) = - 6 - 3n + 3 = - 3n - 3

36 / 12 = x / 9 where x is the model door height
Cross-multiply

324 = 12 *x divide both sides by 12
27 = x and that's the model height in centimeters
What is the domain of the function graphed below?
Answers
Answer:
x < 7
Step-by-step explanation:
the domain is the number range or interval of x the function is defined for to generate a y-value.
the graph shows that the y-values continue with x-values to the right up to but not including 7 (the empty dot says "excluding"). and with x- values to the left to negative infinity.
x=-1 is not a problem, because while for the left part of the function it is not included, but for the right part it is.
so, it is fully defined for all x < 7.

Answer:
(x, y) = (12, -12)
Step-by-step explanation:
The two equations can be added to solve for x.
(-5x -5y) +(6x +5y) = (0) +(12)
x = 12 . . . . . . . . simplify
-5(12) -5(y) = 0 . . . substitute into the first equation

12- 1/5r = 2r + 1
R=??
Answers
Answer:
r = 5
Step-by-step explanation:
12 - 1/5r = 2r + 1
12 - 0.2r = 2r + 1
12 - 0.2r + 0.2r = 2r + 0.2r + 1
12 = 2.2r + 1
12 - 1 = 2.2r + 1 - 1
2.2r = 11
2.2r ÷ 2.2 = 11 ÷ 2.2
r = 5
Answer:
r = 5
Step-by-step explanation:
12- 1/5r = 2r + 1
12 = 11/5r + 1
5(11) = (11/5r)5
55 = 11r
r = 5

Un tubo puede contener 35 l de agua por metro si mide 97 metros ¿Cuanto pesara el agua que contiene al es lleno
Answers
Respuesta:
3395 L
Explicación paso a paso:
Dado que el tubo contiene 35 L de agua por metro.
Esto significa que el volumen por metro del tubo es de 35 litros.
Longitud total del tubo = 97 metros
Volumen de agua en toda la longitud del tubo:
Volumen por metro * 97
35 L * 97
= 3395 litros
Por lo tanto, peso cuando está lleno = 3395 L
