It is a good thing to remember. Of course, not all, but some basic numbers that appear all the time such as the numbers from 2 to 13 should be remembered as they appear in numerous assignments and tests.
Hey! The answer is in the attachment.

The answer is b and c
because they are both parallel to the y-axis
<span>A) 3x+4y=17
B) -4x-3y=-18 Multiplying B) by .75
</span><span>B) -3x -2.25y= -13.5 then adding this to A
</span><span><span>A) 3x + 4y = 17</span>
1.75y = 3.5
y = 2
</span><span>
A) 3x + 4*2 = 17</span>
3x + 8 = 17
3x = 9
x = 3
(3,2)
So first you need to find out how much one water bottle cost.
6/24= 0.25
Okay now you need to find how much it would cost for 10.
so you would times 10 by $0.25:
10*0.25= $2.50
So $2.50 would be you answer.
Hope that helps!!
Have a wonderful day!!
