Answer:

Step-by-step explanation:

hello : let An = 2n - 6

1) the first three terms are :

the first term is : when n= 1 A1 =2(1)-6 = 2-6 = -4

the second term is : when n= 2 A2 = 2(2)-6 = 4-6 = -2

the third term is : when n= 3 A3 = 2(3)-6 = 6-6=0

2) the tenth term is : when n= 10 A10=2(10)-6 =20-6=14

Answer:

Step-by-step explanation:

2n - 6

a) n = 1 ; 2n - 6 = 2*1 - 6 = 2 - 6 = -4

n = 2 ; 2n - 6 = 2*2 - 6 = 4 - 6 = -2

n = 3 ; 2n - 6 = 2*3 - 6 = 6 - 6 = 0

b) n=10; 2n - 6 = 2*10 - 6 = 20 - 6 = 14

I would assume that you would subtract the 2 integrals from each other, the 13 and -3, which will give you 16, and the integral in between 2 to 6, the integral on the right, and then add 2 to 16 which would be 18, I believe that would be the answer.

Answer:

-1/11

Step-by-step explanation:

$\frac{11x}{12} -\frac{1}{6} =\frac{-1}{4}$ add 1/6 to both sides

$\frac{11x}{12} =\frac{1}{6} -\frac{1}{4}$ make the same denominator 12 on the right side

$\frac{11x}{12} =\frac{1}{6}*\frac{2}{2} -\frac{1}{4}*\frac{3}{3}$ solve

$\frac{11x}{12} =\frac{2}{12} -\frac{3}{12} =\frac{2-3}{12} = \frac{-1}{12}$

$\frac{11x}{12}*12 =\frac{-1}{12} *12$ multiply by 12 both sides

11x= -1 divide by 11

x= -1/11

In large cities people out and take taxis to get from one place to another the cost is $25.20 every 36 miles how much is a 47 mi

Kay [80]

47 miles taxi ride will cost $32.9

Step-by-step explanation:

Given,

Cost every 36 miles = $25.20

Cost of one mile = $\frac{Cost\ for\ 36\ miles}{36}$

Cost of one mile = $\frac{25.20}{36}\\$

Cost of one mile = $0.7

Cost of 47 miles = Cost of one mile * 47

$Cost\ of\ 47\ miles = 0.7*47\\Cost\ of\ 47\ miles = \$32.9$

47 miles taxi ride will cost $32.9
