Answer:

Step-by-step explanation:

3x+y+z= 4

3x+ y = 4 - z

y = 4-z-3x

We then make parallel

y-2 = 4−z−3x

y-2 = 4-2 -z-3x

y-2 = 2-z-3x

y = -z-3x+2

Question 4
Snowcat [4.5K]

Answer:

a is 7/25

b is 14/25

c is 24

Step-by-step explanation:

a) because there are 25 possible outcomes and 7 of them are 3 it is 7/25

b) using the same logic 14 possible outcomes are even

c) because the probability of it being 2 is 3/25, which can be made into ?/200 by multiplying the 25 by 8, which means we have to do the same to the 3, making it 24

$40,000 is invested at a rate of 5.7% that is compounded semiannually.
Misha Larkins [42]

Answer:

$$78760.00

Step-by-step explanation:

You want to calculate the interest on $40000 at 5.7% interest per year after 17 years.

The formula we'll use for this is the simple interest formula, or:

I=P*r*t

Where:

  • P is  principal amount, $40,000
  • r is the interest rate, 5.7% per year, or in decimal form, \frac{5.7}{100} =0.057
  • t is the time involved, 17 years

To find the simple interest we multiply 40000*0.057*17 to get

The interest rate is  $38,760

Usually now, the interest is added onto the principal to figure some new amount after 17 years.

or 40000.00 + 38760.00 = 78760.00

=$78,760
