Molodets [167]3 years ago
4 0

Answer:

The solution is x=2 and y=-1

Step-by-step explanation:

(step 1)

4x + 2y = 6

x - y = 3 - then multiply by 2

4x +2y = 6

<u>2x -2y = 6</u> then add

6x  x   = 12 x = 12/6 = 2

Substitue back in (step 1)

4 x 2 + 2y = 6

   8 + 2y = 6

Answer is = 2y = -2  y= -1

Solution: x= 2

               y= -1

Assume that a 30-month CD purchased for $2500pays simple interest at an annual rate of 5.5%. How much total interest does it ear
otez555 [7]

Answer:

Interest earned: 343.75

Balance at maturity: 2843.75

Step-by-step explanation:

simple interest formula

P(1+it)

interest earned:

(interest earned is the ending balance minus the beginning balance)

2500(1+.055*(30/12))-2500= 343.75

Balance at maturity

2500(1+.055*(30/12))= 2843.75

(another way to solve this part is to just add 343.75 (the interest earned) to the beginning balance)

Australia is 2.97 x 106 square
Arlecino [84]

Answer:1.7

Step-by-step explanation:

First you want to multiply 2.97 by 106

2.97 x 106 = 314.82

Now you want to multiply 1.72 by 107

1.72 x 107 = 184.04

Now you want to divide them

314.82 / 184.04 = 1.71

Now you want to round it to the nearest tenth... if a number is 5 or above you round it up but if it is 4 or below your number stays the same

Since 1 is lower than 5 you keep your number the same

<u>1.7</u>
