V - 17 = -29
v = -29 + 17
v = -12
The 17 is now positive because it have been flipped to the other side.
For example:
2x - 14 = -20 -4x
2x + 4x = -20 + 14
6x = -6
Exterior angle sum gives 9x=5x+9+x
9x=6x+9
3x=9
x=3

<u>This means that the side length of the cube is 3 units. The volume, which we previously stated was equal to s3, must then be 33, or 27 cubic units. The answer is 27.</u></h3>
Answer:
c = ½(p + 2s)
Step-by-step explanation:
Let c = the total cost
p = cost of one shirt
2s = cost of two sweaters
p + 2s = total cost before discount
But Alana paid only half the regular price, so
c = ½(p + 2s)
Answer:
1050, 1200, 2550 and 5100.
Step-by-step explanation:
If the first number is x then the second is x + 1/7x.
The third = x + x + 1/7x + 300 and the fourth = x + x + 1/7x + x + x + 1/7x+ 300 + 300.
So our equation is:-
8x + 4 * 1/7x + 900 = 9900
60/7 = 9000
60x = 7*9000
x = 1050.
Therefore the 4 numbers are 1050, *1/7*1050 = 1200, 2550 and 5100.
