Answer:
$110
Step-by-step explanation:
The computation is shown below:
Provided that
Number of desk purchased Fund Left $
0 700
1 590
2 480
3 370
4 260
5 150
6 40
Now the Fund decreased while purchasing is
= 5 desks - 2 desks
= 3 desks
i.e
= $480 - $150
= $330
Now the amount of money left for decreased the desk fund is
= $110
Answer:
3. [1, −2]
2. [−3, 3]
1. [−7, 10]
Step-by-step explanation:
3.
{7⁄2x - ½y = 9⁄2
{3x - y = 5
-6⁄7[7⁄2x - ½y = 9⁄2]
{−3x + 3⁄7y = −3 6⁄7 >> New Equation
{3x - y = 5
_________________
-4⁄7y = 1 1⁄7
-2 = y [Plug this back into both equations above to get the x-coordinate of 1]; 1 = x
__________________________________________________________
2.
{−3x + 9y = 36
{4x + 12y = 24
¾[4x + 12y = 24]
{−3x + 9y = 36
{3x + 9y = 18
______________
18y = 54
___ ___
18 18
y = 3 [Plug this back into both equations above to get the x-coordinate of −3]; −3 = x
__________________________________________________________
1.
{4x − y = −38
{x + y = 3
_____________
5x = -35
___ ____
5 5
x = -7 [Plug this back into both equations above to get the y-coordinate of 10]; 10 = y
I am joyous to assist you anytime.
Well you are trying to find x, so you would divide 5/8 by itself and on the other side.
(5/8x / 5/8) = (10 / 5/8)
x=16
Hope this helps!
Find the LCD = 18
5/6 = 15/18
3/9 = 6/18
15/18 + 6/18 = 21/18 = 7/5 or 1 2/5
So 6+3 is 9 right? So let's just say it's 9:37 with a 45 min ride. 60 minutes are in a hour. 60 - 37 = 23. We have 23 minutes left until 10:00. 45- 23 = 22. Therefore it'd be 10:22 p.m.
