The correct answer is x=3.5
Volgvan3 years ago
5 0

Answer: x = 3.5

Step-by-step explanation:

We can start by subtracting 5 from both sides:

2x - 5 = 12 - 5      Which will come out to: 2x = 7

Then we divide both sides by 2 so that we can isolate the variable:

2x/2 = 7/2       Which will come out to: x = 3.5

Find the fifth term of a sequence whose first term is 8 and common ratio is 3/2
Arlecino [84]

Answer:

Option c. 81/2

Step-by-step explanation:

Fifth term: a5=?

First term: a1=8

Common ratio: r=3/2

an=a1*r^(n-1)

with n=5

a5=a1*r^(5-1)

a5=a1*r^4

Replacing the known values:

a5=8*(3/2)^4

a5=8*(3)^4/(2)^4

a5=8*81/16

Simplifying: Dividing the numerator and denominator by 8:

a5=(8*81/8)/(16/8)

a5=81/2

Answer: Option c. 81/2

babunello [35]
If x is the amount that Tanya paid for each item, then Tony's items would be x-2.25. So:
3x=4(x-2.25)

3x=4x-9
x=9
x-2.25=6.75
Tanya spent $9 on each item; Tony spent $6.75 on each of his items
