Flauer [41]

Answer:

a = 16

Step-by-step explanation:

inversely proportional

y = k/x

a = k/b

Blizzard [7]

Answer:

Eric,Tony,Jeff,Gary

Step-by-step explanation:

Given the payments made by each individual below:

  • Tony paid 35% of the bill.
  • Eric paid 3/8 of the bill.
  • Jeff paid 0.175 of the bill
  • Gary paid 1/10 of the bill.

The most convenient way to order their payments is to convert each to percentage.

Eric paid 3/8 of the bill.

  • In Percentage: \frac{3}{8}X100=37.5\%

Jeff paid 0.175 of the bill

  • In percentage, 0.175 X100 =17.5%

Gary paid 1/10 of the bill.

In Percentage: \frac{1}{10}X100=10\%

Therefore, the order from most to least is:

Eric(37.5%), Tony(35%),Jeff(17.5%),Gary(10%)

Solve for x: 20x2 - 7x = 6
azamat

Answer:

if the x after the 20 means multiply then the answer is -34/7 or -4 6/7 if the x is a letter then it's 2/11

Step-by-step explanation:

20x2-7x=6

20x2=40

40-7x=6

subtract 40 from 6= 34

-7x=34

34÷-7= -34/7 if needed in a mixed fraction -4 6/7

Which ordered pair is the solution to the system of equations?<br><br><br><br> {x+2y=−8y=12x−2
sukhopar [10]

Answer:

x + 2y = -8

y = 12x - 2

x + 2(12x - 2) = -8

x + 24x -4 = -8

25x - 4 = -8

25x = -4

x = -4/25

y = 12(-4/25) - 50/25

y = -48/25 - 50/25

y = -98/25
