Answer:
$345
Step-by-step explanation:
35(15)-180
345
Answer:
Step-by-step explanation:
Two sheets will cost: $27
The value of the first sheet will be $18, and since the other sheet is half off it will be half of the original value: 18 * 0.5 = 9.
Then you add the values together: 18 + 9 = 27.
Six sheets will cost: $81
For every sheet that is the original value there is a sheet that is half off. So since there are six sheets, 3 of the sheets will be $18 and three of them will be $9. We already know that 18+9=27, so just multiply that value by 3.
27*3= 81
Better deal: The second example
In the second example sheets are 30% off. 30% of 18 is $6. Subtract that value from 18 and you will get $12. In the second example one sheet is $12.
If we multiply that value by 2, we will get $24.
In the first example, two sheets costs $27, while in the second example two sheets cost $24. Since the cost is less for the second example, the second example is the better deal.
C - 0
If you put 0 into the graph (as an x value), your output would be 0.
Answer:
Step-by-step explanation:
(x+6)(x+4)(x-3)
= [(x+6)(x+4)](x-3)
= (x² + 4x + 6x + 24)(x - 3)
= (x² +10x + 24)(x - 3)
= x³ - 3x² + 10x² - 30x + 24x - 72
= x³ + 7x² - 6x - 72
Answer:
h = -1
Step-by-step explanation:
Solve for h:
16 h - 9 = -6 h - 31
Add 6 h to both sides:
16 h + 6 h - 9 = (6 h - 6 h) - 31
6 h - 6 h = 0:
16 h + 6 h - 9 = -31
16 h + 6 h = 22 h:
22 h - 9 = -31
Add 9 to both sides:
22 h + (9 - 9) = 9 - 31
9 - 9 = 0:
22 h = 9 - 31
9 - 31 = -22:
22 h = -22
Divide both sides of 22 h = -22 by 22:
(22 h)/22 = (-22)/22
22/22 = 1:
h = (-22)/22
The gcd of -22 and 22 is 22, so (-22)/22 = (22 (-1))/(22×1) = 22/22×-1 = -1:
Answer: h = -1
