Answer:
Step-by-step explanation:
To find the nth term of a geometric sequence, you have the general formula:
where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):
135 = 
135 = 
135 = 
Now, we can substitute the first term back in:
If it costs 3n+5, you have to plug 7 in for n and solve. 3(7)+5=26 so $26

Answer: 10-pound bag for $4.58
Step-by-step explanation:
A store sells potatoes in 5-pound bags for $2.29. To get the amount for a pound bag of potatoe, we divide $2.29 by 5. This will give:
$2.29 / 5 = $0.458
To get the amount equivalent goes thus:
For a 20-pound bag for $8.80, a pound will cost:
$8.80/20 = $0.44
For a 2-pound bag for $1.02, a pound bag will be:
$1.02/2 = $0.51
For a 10-pound bag for $4.58, a pound bag will cost:
$4.58/10 = $0.458
For a 7-pound bag for $3.01, a pound bag will cost:
$3.01/7 = $0.43
From the figures calculated, a 10-pound bag for $4.58 is the same as the amount calculated.
Hey there! I’m happy to help!
Let’s use the variable g to represent the girls. This ratio shows that there are twice as many boys as girls (boys=2g)We also see that there are 18 more boys that girls. Let’s set up an equation
g+18=2g
We subtract 18 from both sides
g=2g-18
We subtract 2g from both sides.
-g=-18
We divide both sides by -1
g=18
Therefore, there are eighteen girls.
I hope that this helps! Have a wonderful day!
