If x is the smallest of the three, then the next two integers are x + 2 and x + 4.

"Twice the largest is 20 less than the sum of all three" translates to

2 (x + 4) = (x + (x + 4) + (x + 6)) - 20

Solve for x :

2x + 8 = 3x - 10

x = 18

Then the three numbers are {18, 20, 22}.

Answer:look below

Step-by-step explanation:Let x, x+2 & x+4 be the 3 integers.

x+2(x+2)=(x+4)+20

x+2x+4=x+4+20

3x+4=x+24

3x-x=24-4

2x=20

Can someone write an explicit formula for the following sequence for me?:

Phoenix [80]

Answer:

$a_n=10-7n$

Step-by-step explanation:

The explicit form for an arithmetic sequence is:

$a_n=a_1+d(n-1)$

where $a_1$ is the first term and [ted]d[/tex] is the common difference.

The given sequence is arithmetic because term-previous term is the same per each pair of term and previous term.

That is the following holds:

-4-3=-11-(-4)=-18-(-11)

All of these differences are equal to -7, the common difference.

So let's fill in the explicit form:

$a_n=3+-7(n-1)$

$a_n=3-7(n-1)$

$a_n=3-7n+7$

$a_n=10-7n$

Nana76 [90]

Subtract the part from the total:

102.50 - 15 = 87.50

Now divide the remainder by rate:

87.50 / 25 = 3.5 hours

Malik collects rare stamps and has a total of 212 stamps. He has 34 more domestic stamps than foreign stamps. Let x represent th

cluponka [151]

Answer:

foreign: 89
domestic: 123

Step-by-step explanation:

Add the two equations together:

(x -y) +(x +y) = (34) +(212)

2x = 246

x = 123

y = x-34 = 89

Malik has 89 foreign stamps and 123 domestic stamps.
