Answer:
c=120x+200y
Step-by-step explanation:
La expresión algebraica debería indicar que el valor total que debe cobrar Flor es igual a 10 que representa el número de bolsas por el resultado de la suma del precio de cada item por la cantidad, lo que se puede expresar de la siguiente forma:
c=10(12x+20y)
c=120x+200y
De acuerdo a esto, la expresión algebraica que permite saber cuánto debe cobrar Flor por 10 bolsas que contengan x cantidad de lápices y "y" cantidad de bolígrafos es c=120x+200y.
Answer:
The answer is B.
Step-by-step explanation:
You have to use area of trapezoid formula, A = 1/2×(a+b)×h where a, b are the side lengths and h is height :
A. Your Choice
B. Green (Your Choice, but the other answers are only applicable if you use 1 color.)
C. Same color
D. The walls are 8 * 20 ft and 8 * 25 ft, and there are 2 of each of those.
That means you are painting 720 ft^2
There is 1 gallon per 400 ft^2, so you need 2 gallons of paint.
It costs $13.98 per gallon, so you need $13.98 * 2 = $27.96
(2, 4) is the correct answer
Answer:
I guess that you want to calculate the difference between the annual healt care costs in 1950 and today.
The equation is:
C(x) = $620*(1.082)^x
in 1950, we have x = 0 (because is the initial year)
then the cost is:
C(0) = $620*1 = $620.
Now, today, in 2020, we have:
x = 2020 - 1950 = 70
then we have:
C(70) = $620*(1.082)^70 = $154,276.7
So, according to this equation, te difference is:
$154,276.7 - $620 = $153,656.6
