Given the below sequence:

kvasek [131]

Answer:

a) The next three terms are -1,-3,-5,-7,-9,-11,-13

b) This is arithmetic sequence

C) The difference of second term and first term is -2 in given sequence so the given sequence is an arithmetic sequence.

d) The 27 th term is -53

Step-by-step explanation:

a) the given sequence is arithmetic sequence

the difference of second term and first term is -2

given sequence is -1,-3,-5,-7.....

the nth term in arithmetic sequence

$t_{n} = a+(n-1)d$

First term is a = -1 and difference is d = -2

finding fifth term is

$t_{5} = -1 +(5-1)(-2)$

$t_{5} = -1-8 =-9$

finding sixth term is

$t_{6} = -1 +(6-1)(-2)$

$t_{6} = -1-10 =-11$

finding seventh term is

$t_{7} = -1 + (7-1)(-2)$

$t_{7} = -1 -12 =-13$

The next three terms are -9,-11,-13

The given sequence is -1,-3,-5,-7,-9,-11,-13

b) This is arithmetic sequence.

C) because the difference of second term and first term is -2 so the given sequence is arithmetic sequence.

d) by using nth term formula in arithmetic sequence

$t_{n} = a+(n-1)d$

a= -1 and d =-2

find 27 t h term :-

$t_{27} = -1 + (27-1)(-2) = -1-52=-53$

Answer:

x = 0

x = 7/5

x = -2/3

Step-by-step explanation:

x2 =0

x=0

5x -7 =0

5x = 7

x = 7/5

3x+2 =0

3x = -2

x = -2/3

These are all the 3 roots of this equation

Jeff has two sticker-printing machines. Each machine can print 42 stickers per minute. On day 1, only the first machine was used

tankabanditka [31]

All you have to do is x times 42 plus y times 42 and then you have to add the first day on which is 89.This is how it should look (x*42)+(y*42)+89.

You are remodeling your kitchen. You've contacted two tiling companies who gladly told you how long it took their workers to til

Ray Of Light [21]

The answer is 7x = 6(x + 15)

x - Jim's rate
y - Pete's rate
Jim completed half the floor in 7 hours: 7x = half of the floor
Pete completed the other half of the floor in 6 hours: 6y = half of the floor
So: 7x = 6y

Pete can lay 15 more tiles per hour than Jim: y = x + 15

7x = 6y
y = x + 15

Substitute the second equation into the first one:
7x = 6(x + 15)
