Friend = -12°C
you = -54°C

difference = 54 - 12
= 42 degrees.

12 degrees below zero tells you we have a negative number, -12. The word "Difference" means we are subtracting. So your equation will be 54 - (-12). Two minuses/negatives back-to-back turn into a plus so the equation is now 54 + 12 = 66.

There is a 66 degree difference in temperatures assuming the temperatures given are using the same units (I mean one is not Celsius and the other Fahrenheit).

Anna starts a fixed deposit with $178000, the bank offers 9.5% per year simple interest for 8 months. she has the option of rest
soldier1979 [14.2K]

Using simple interest, we have that:

A) The interest due after 8 months is $11,272.33.

B) The total value of the investment will be of $189,986.24.

The amount of interest earning using <em>simple interest</em>, after <u>t years</u>, with an <u>yearly interest rate of i</u> and an <u>initial investment of P</u> is given by:

E = Pit

In this problem:

  • Deposit of $178,000, hence P = 178000.
  • Interest rate of 9.5% per year, hence i = 0.095.
  • 8 months, the time is in years, hence t = \frac{8}{12} = \frac{2}{3}

Item a:

E = Pit

E = 178000(0.095)\frac{2}{3} = 11272.33

The interest due after 8 months is $11,272.33.

Item b:

For the second interest, we consider P = 11272.33, hence:

E_2 = Pit

E_2 = 11272.33(0.095)\frac{2}{3} = 713.91

The total value will be composed by:

  • The initial deposit of $178,000.
  • The first interest of $11,272.33.
  • The second interest of $713,91.

Hence, it will be:

T = 178000 + 11272.33 + 713.91 = 189986.24

The total value of the investment will be of $189,986.24.

Use substitution to solve the system<br><br> 2y - 8 = x<br><br> 2x + 3y = -2
devlian [24]

Answer:

x=2y-8

We use the substitution of x in the second equation

2*(2y-8)+3y= -2

4y-16+3y=-2

7y-16= -2

7y= -2 +16

7y=14

y=14Ș7

y=2

so x= 2*2 -8

    x=4-8

    x=-4

the solution is  (x,y)=(-4, 2)
