So you're suppose to isolate the variable by dividing each side by factors that don't contain the variable.
Which equals or at least.. Makes x = −

I hope this helps, as always. I wish you the best of luck and have a nice day, friend..
Answer:
the first term is a1
the distance between the numbers is d
we have:
a5 = a1 + 4d = 23
a12 = a1 + 11d = 72
so we have the equation:
a1 + 4d = 23
a1 + 11d = 72
=> a1 = -5
d = 7
=> an = -5 + 7(n - 1) = 7n - 12
with an = 7n - 12
=> a2 = 2
a3 = 9
so the first three terms is -5; 2; 9
Answer:
6
Step-by-step explanation:
Remember, the mean is the average. To find the average of a data set, add the numbers together, then divide by the number of options.
Since there was 4 people here, think about this:
Add the three people's results together.
6+5+4=15
Now, what number, when divided by 4 (because 4 people), gets 4 (for the mean)?
16
16-15=1
So, Hannah blew 1 bubble.
Step-by-step explanation:
Step one:
The farmer sells his corn for $230 a metric ton
small surcharge = $25.
let the amount per metric ton be x
and let the total cost per x metric ton be y
the total cost function is
y=230x+25--------------1
The neighbor sells her corn for $230 a metric ton
he gives $15 rebate------<em>A rebate is a partial refund of the cost of an item</em>
let the amount per metric ton be x
and let the total cost per x metric ton be y
the total cost function is
y=230x-15----------------2
Step two:
Equating the two equation above
230x+25=230x-15
230x-230x=25+15
0=40
The result shows that based on the cost function of both farmer, there will never be an amount of corn that would make them have the same cost
