Find the nth term for the sequence 6 12 22 36 54

MissTica

It’s 76 because 6+6=12 and 12+10=22 so if you add 4 to the last one and you add the last number you get the next one. So, 22+14= 36 36+18= 54 so 18+4= 22 and 22+54= 76. Hope it helps!

How many 3-digit even numbers are there that begin with either 5 or 6?

Ray Of Light [21]

Answer:

100 numbers

Step-by-step explanation:

There are 100 numbers with 5 as the hundreds digit. (500-599)

There are 100 numbers with 6 as the hundreds digit. (600-699)

There are 50 even numbers with 5 as the hundreds digit.

(500, 502, 504, ... , 598)

There are 50 even numbers with 6 as the hundreds digit.

(600, 602, 604, ... , 698)

50+50=100 numbers

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 980 square feet. The width of the basem

Serhud [2]

This problem requires a system of equations.

Let x be the length and y be the width.

xy = 980 x = 5y

Substitute 5y for x.

5y(y) = 980
5y² = 980
y² = 980/5
y² = 196
y = √196
y = 14 feet

Substitute 14 for y.

x = 5y
x = 5(14)
x = 70 feet

The length is 70 feet.

The population of Jose’s town in 1995 was 2400 and the population in 2000 was

Gnom [1K]

Answer:

$y=320x+2400$

Step-by-step explanation:

Remember, a line has the form $y=mx+b$ , where $m$ is the slope and $b$ is the y-intercept. In this cases, y represents the population when have been passed x years since 1995.

Since x represent the number of years since 1995, then in 1995, x=0 and the population is 2400. Then a point of the linear equation is (x,y)=(0,2400).

In 2000 has been passes 5 years since 1995 and the population is 4000, this means that x=5 and y=4000. Then other point in the line is (x,y)=(5,4000)

For find the equation of the line that describe the preview situation we use the points found.

Remember, if $(x_1, y_1)$ and $(x_2,y_2)$ are pointsin the plane, the slope of the line that passes through the points is
