Value x as the weight of the large box, y as the weight of the small box

7x + 9y = 157 (1)
5x + 3y = 89 -> 15x + 9y = 267 (2)

(2) - (1) => 8x = 110

=> x = 13.75 kg
=> (1) => 5x13.75 + 3y = 89 => 3y = 20.25 => y = 6.75 kg

So, large box weigh 13.75 kg, and small box weigh 6.75 kg

Find the accumulated value of an investment of $7000 at 12% compounded semiannually for 12 years.
Mashcka [7]

Answer:

  $28,342.54

Step-by-step explanation:

The value of an account earning compound interest is found using the formula ...

  A = P(1 +r/n)^(nt)

where P is the principal invested at annual rate r compounded n times per year for t years.

__

You have P=7000, r=0.12, n=2, t=12.

Using these values in the formula, we find the accumulated value of the investment to be ...

  A = 7000(1 +0.12/2)^(2·12) = 7000(1.06^24) ≈ 28,342.54

The value after 12 years is $28,342.54.

-11 minus 5b = -6b minus 3
LiRa [457]

Answer:

b = 8

Step-by-step explanation:

-11 - 5b = -6b - 3

add 11 to both sides:

-5b = -6b + 8

add 6b to both sides:

-5b + 6b = 8

simplify:

b = 8
