Answer:
x = 0
y = -3
Step-by-step explanation:
-5x + y = -3 --------------(I)
3x - 8y = 24 ------------(II)
Multiply the equation (I) by 8
(I)*8 - 40x + 8y = -24
(II) <u> 3x - 8y = 24</u><u> </u> {Add and y will be eliminated}
-37x = 0
x = 0
Plugin x = 0 in equation(I)
-5*0 + y = -3
0 + y = -3
y = -3
Answer:
269
Step-by-step explanation:
6(3)+23+(7)(33)-3

18 + 23 + 231 - 3 = 269
Find the area of the room by multiplying the length by the width:
Area of room = 20 x 12 = 240 square feet.
Find the area of the tile: 2x 2 = 4 square feet.
To find the number of tiles divide the area of the room by the area of a tile:
240/4 = 60
They will need 60 tiles.
Answer:
The answer is y = -1/3x - 1
Step-by-step explanation:
In order to find this we first must note that parallel lines have the same slope. Therefore, since the slope in the original line is -1/3, then we know the slope in our line will be the same. Now we can use point slope form with that slope and the given point to find the equation by solving for y.
y - y1 = m(x - x1)
y + 3 = -1/3(x - 6)
y + 3 = -1/3x + 2
y = -1/3x - 1
<span>2 3/4 divided by 1 1/4 is.......
2.2
Steps:
Follow the rule KCF (keep) (change)(flip)
1) keep the first number ( don't do anything to it) (just change it to improper which is 11/4
2) change the division sign into multiplication
3) Change 1 1/4 into improper which will be 5/4 and then flip it
4) Multiply 11/4 and 5/4 which gives you..... </span>
