-4(1-6b)-5(2b-6)=8b-7b

We move all terms to the left:

-4(1-6b)-5(2b-6)-(8b-7b)=0

We add all the numbers together, and all the variables

-4(-6b+1)-5(2b-6)-(+b)=0

We multiply parentheses

24b-10b-(+b)-4+30=0

We get rid of parentheses

24b-10b-b-4+30=0

We add all the numbers together, and all the variables

13b+26=0

We move all terms containing b to the left, all other terms to the right

13b=-26

b=-26/13

b=-2

What is the volume of this rectangular prism? <br> 3ft by 6 1/4 ft by 14 ft
Liula [17]
We can find the volume of any rectangular prism by simply multiplicating its height, length and width.

Also, lets change that 6 1/4 to 6.25, or 25/4 if you like. I’m gonna use 6.25.

If we take volume as “V”, then:

V = L * W * H
V = 3ft * 6.25ft * 14ft
V = 262.5 ft^3 (Its ft cubed because we multiplied by ft three times.)

Which formula can be used to find the nth term of a geometric sequence where the fifth term is 1/16 and the common ratio is 1/4
stepladder [879]
A₅ = 1/16  and r= 1/4

Let see how to build up this formula that is going to give that term of rank n

1st term =a₁ = To be calculated

1st a₁   = a₁  x  r°
2nd a₂  = a₁  x  r¹
3rd a₃  =  a₁  x  r²
4th a₄   = a₁  x  r³
5th a₅   = a₁  x  r⁴
.......................
.......................
nth : a(n) = a₁  x r⁽ⁿ-¹)
Note when that the subscript of a is the same as the exponent mines 1

We know the ratio r =1/4 & the fifth term, a₅ =1/16 (given). Now let's apply the formula to calculate the unknown a₁.

a(n) = a₁  x r⁽ⁿ-¹) ==>a₅ = a₁ x (1/4)⁽⁵⁺¹⁾ ===> 1/16 = a₁ x (1/4)⁴
1/167 = a₁ (1/256) ==> a₁ =16 & the formula becomes
a₅ = 16(1/4)⁴
