Answer & Steps:

I just left everything in fraction form unless it's equal to a whole number. Wasn't sure how you wanted it to be simplified

16) \frac{2}{3} + \frac{1}{4} = \frac{8}{12} + \frac{3}{12} = <u>11/12</u>

17) 1/2 + 2/5 = 5/10 + 4/10 = <u>9/10</u>

18) 3/10 + 4/5 = 3/10 + 8/10 = <u>11/10</u>

19) 3/4 + 3/8 = 6/8 + 3/8 = <u>9/8</u>

20) 2/7 + 1/2 = 4/14 + 7/14 = <u>11/14</u>

21) 1/6 + 3/4 = 2/12 + 9/12 = <u>11/12</u>

22) 10/15 + 2/5 = 10/15 + 6/15 = <u>16/15</u>

23) 1/2 + 4/9 = 9/18 + 8/18 = <u>17/18</u>

24) 2/3 + 3/5 = 10/15 + 9/15 = <u>19/15</u>

25) 3/4 + 3/12 = 9/12 + 3/12 = 12/12 = <u>1</u>

26) 5/6 + 1/18 = 15/18 + 1/18 = 16/18 = <u>8/9</u>

27) 1/3 + 5/6 = 2/6 + 5/6 = <u>7/6</u>

28) 3/4 + 5/6 = 9/12 + 10/12 = <u>19/12</u>

29) 1/3 + 2/7 = 7/21 + 6/21 = <u>13/21</u>

30) 5/12 + 3/8 = 10/24 + 9/24 = <u>19/24</u>

31) 3/5 + 1/6 = 18/30 + 5/30 = <u>23/30</u>

What is the solution to the system: 9x+3y=24 2y+4x=8
egoroff_w [7]

Answer:

x = 4, y = -4

Step-by-step explanation:

9x + 3y = 24

3x + y = 8                       divide both sides by 3

y = 8 - 3x                        subtract 3x from both sides

2y + 4x = 8

2(8 - 3x) + 4x = 8             replace y with 8 - 3x

16 - 6x + 4x = 8                distributive property

-6x + 4x = 8 - 16               subtract 16 from both sides

-2x = -8                            divide both sides by -2

x = 4

y = 8 - 3x

y = 8 - 3(4)                        replace x with 4

y = 8 - 12

y = -4

Please don't use just for the points I actually need help with this
Tems11 [23]

Answer:

Cost before sales tax= 16 dollars

Total cost= 17.16 dollars

Step-by-step explanation:

We know the sales tax rate is 7.25 percent.

To find the cost from the tax rate, we divide the cost of the sales tax by the rate.

1.16/0.0725 = 16 dollars

Now to find the total cost, add the cost before the tax rate by the sales tax amount.

16+1.16= 17.16 dollars
