Answer:

Step-by-step explanation:

8x + 6y = 48.....reduces to 4x + 3y = 24

2x - 3y = -6

4x + 3y = 24

-------------------add

6x = 18

x = 18/6

x = 3

2x - 3y = -6

2(3) - 3y = -6

6 - 3y = -6

-3y = -6 - 6

-3y = -12

y = -12/-3

y = 4

solution is : (3,4)

the ordered pair (3,4) lies in quadrant I

the x coordinate of the solution is 3

the y coordinate of the solution is 4

I would like to purchase 20 products at a cost of $65 per product. What would be my total with 3.5 sales tax

alexandr402 [8]

Answer:

Answer:

The total is: $ 1345.5

Step-by-step explanation:

It is given that:

I would like to purchase 20 products at a cost 65.00 per product.

This means that the cost of 20 products will be:

Also, there is a sales tax of 3.5%

This means that a person has to pay a extra 3.5% on the total cost of the items he purchased.

i.e. he need to pay 3/5% on $ 1300

This means that the amount of tax he need to pay is: 3.5% of 1300

= 3.5%×1300

= 0.035×1300

= $ 45.5.

Hence, the total cost is: $ 1300+$ 45.5

This means that the total cost is: $ 134.5

Find the surface area of the prism. 12 in. 6 in. 5 in. The surface area is in.2.

Ber [7]

Answer:

324

Step-by-step explanation:

SA = 2 ( lw + hl + hw )

l = length

w = width

h = height

Given Dimensions

l = 6

w = 5

h = 12

* plug in to SA formula *

SA = 2 ( (6)(5) + (12)(6) + (12)(5) )

(6)(5) = 30

(12)(6) = 72

(12)(5) = 60

SA = 2 ( 30 + 72 + 60 )

30 + 72 + 60 = 162

SA = 2(162) = 324

Answer:

annex the questions of the questionnaire because it is incomplete and the answers are made below

Step-by-step explanation:

7. Value of adrian investment in 10 years =

$10000(1+0.057)^10 = $17,408

8. Value of Clemen's investment in 10 years =$10000(1+0.068)^10 = $19,306

9. Additional value of Clemen's investment

over Adrian's investment over 10 years time = $19306-$17408= $1,898

10. Value of Adrain investment in 20 years =$10000(1+0.057)^20= $30,303 Value of Clemen's investment in 20 years =$10000(1+0.068)^20= $37,275

Additional value of Clemen's investment

over Adrian's investment over 20 years time = $37275-$30303= $6,972
