Answer:

a =8

Step-by-step explanation:

-7 - 3a = 1 - 4a

add 3a to both sides

-7 - 3a + 3a = 1 -4a + 3a \\-7 = 1 -a

add -1 to both sides

-7 - 1 = 1 - a -1\\-8 = -a

multiply both sides by -1

-8 * (-1) = -a * (-1) \\8 = a

Dovator [93]

The number of years it would take $4000 to grow to $4616 is 2.92 years.

<h3>How many years would it take the investment to have a value of $4616?</h3>

When an amount earns compound interest compounded semi annually, it means that both the amount invested and the interest accrued increases in value twice yearly.

Number of years = (In FV / PV) / r

  • r = 9.8/2 = 4.90%
  • FV = future value = 4616
  • PV = present value = 4000

(In 4616 / 4000) / 0.049 = 2.92 years

Feliz [49]

Answer:

The greatest number of stamps that Nathan can put on each page = 16.

Step-by-step explanation:

Given:

Nathan has:

80 US stamps

64 Canadian stamps

32 Mexican stamps

The stamps need to put on a page such that each page has same number of same country stamps on each page.

To find the greatest number of stamps he can put on each page.

Solution:

In order to find the greatest number of stamps Nathan can put on each page, we will find the G.C.F. of the three numbers.

The numbers are:

80,64,32

<em>We will list down the prime factors of each number.</em>

80=2\times 2\times 2\times 2\times 5

64=2\times 2\times 2\times 2\times 2\times 2

32=2\times 2\times2\times 2\times 2

The G.C.F can be given as = 2\times 2\times 2\times 2 = 16

Thus, the greatest number of stamps that Nathan can put on each page = 16.
