3x+50+6x-10=180
I combined the two equations and now you can solve for x
start by adding 3x plus 6x and subtracting 10 from 50 and you get a new equation
9x +40 =180
now from here you should be able to do the rest
just subtract 40 from 180 to get 9x=140
and what is 140 divided by 9

Given:
Natalie buys a cooper wire that is 3 feet long.
The cost of the wire is $1.25 per foot.
Question asked:
What is the total cost, in dollars, of Natalie's wire?
Solution:
<u>By unitary method:</u>

Each foot of wire cost = $1.25
3 feet of wire cost = $1.25
3 = $3.75
Thus, total cost of wire is $3.75
Just take the number of blocks there are and divide them amongst the number of people sharing the blocks.
For 5 people sharing 2 blocks:
