Answer:
Option a. $300
Step-by-step explanation:
Let
x ----> the cost of the rent monthly per person
we know that
The number of persons is 3 (Sal and two friends)
The cost of the security deposit per person is equal to
If Sal paid a total of $1,000 to move in
then
That means that the cost per person of two months of rent (first and last month) plus $400 (security deposit per person) must be equal to $1,000
solve for x

Answer:
5/10 or 1/2
Step-by-step explanation:
Beth ate 2/10 so 2/10+3/10+2/10=5/10=1/2
If you would like to solve 2x + 5y = -13 and 3x - 4y = -8, you can do this using the following steps:
2x + 5y = -13 /*4
3x - 4y = -8 /*5
_______________
8x + 20y = -52
15x - 20y = -40
_______________
8x + 15x + 20y - 20y = -52 - 40
23x = -92
x = -92 / 23
x = -4
<span>3x - 4y = -8
</span>3 * (-4) - 4y = -8
-12 - 4y = -8
12 + 4y = 8
4y = 8 -12
4y = -4
y = -1
The correct result would be x = -4 and y = -1.
