Answer:

x=\frac{9}{157} \\y=-\frac{105}{157}

Step-by-step explanation:

-6x-5y=64x+y=3

-6x-5y=64x+y

-6x-64x=y+5y

-70x=6y

divide by 2

-35x=3y

y=-(35/3)x

y+64x=3

-(35/3)x+64x=3

-35x+192x=9

157x=9

x=9/157

y=-35/3x

y=-\frac{35}{3} \times\frac{9}{157} \\y=-\frac{105}{157}

A sum of money invested at 8% per annum for simple interests amounts to $12122 in 2 years.What ill it amounts to in 2 years 8 mo
Jobisdone [24]

Answer:

  $12,958

Step-by-step explanation:

The total amount of the account, principal plus interest, is given by ...

  A = P(1 +rt)

The given information tells us ...

  12,122 = P(1 + .08×2) = 1.16P

Then the principal amount is ...

  12,122/1.16 = 10,450

__

When that same amount is invested using a different rate and time period, it becomes ...

  A = 10,450(1 + .09×(2 2/3)) = 10,450×1.24 = 12,958

It will amount to $12,958 in 2 years 8 months at 9%.

75 - 3.5x - 4x = 4x + 6
stepladder [879]

Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

75 - 3.5x - 4x = 4x + 6

Step 2: Solve for <em>x</em>

  1. Combine like terms: 75 - 7.5x = 4x + 6
  2. Add 7.5x on both sides: 75 = 11.5x + 6
  3. Subtract 6 on both sides: 69 = 11.5x
  4. Divide both sides by 11.5: 6 = x
  5. Rewrite x = 6

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

75 - 3.5(6) - 4(6) = 4(6) + 6

75 - 21 - 24 = 24 + 6

54 - 24 = 30

30 = 30
