7x+8y=−46 2y − 6=0 What is the solution (x,y) to the system of equations above?

Mathematics
1 answer:
yarga [219]2 years ago
8 0

Answer:

(-10, 3)

Step-by-step explanation:

You can do it algebraically (substitution or elimination) or graphically. I will be using substitution to solve this.

Step 1: Rewrite 2nd equation

2y = 6

y = 3

Step 2: Plug in <em>y</em>

7x + 8(3) = -46

7x + 24 = -46

7x = -70

x = -10

Put it in coordinates and we have our final answer!

Nicole can buy 3 pounds of Luce suppose an orchard for $4.95 or she can buy a 25 ounce bag of apples from the store for $3.79 w

Answer:

  orchard apples are lower-cost

Step-by-step explanation:

3 pounds is 48 ounces, so the equivalent to the store offering might be about 24 ounces for $4.95/2 ≈ $2.48.

This is substantially less cost per ounce than 25 ounces for $3.79. (24 and 25 are very near, but $2.48 and $3.79 are not.)

Orchard apples are the better deal.

A basketball was originally priced at $25, but Tucker waited to buy it until the basketball was on sale for 20% off. If he paid
kotegsom [21]

Answer:

The answer to your question is $21.0

Step-by-step explanation:

Data

Original price = $25

Discount = 20%

Taxes = 5%

Process

1.- Calculate the price with the discount

                     $25 ------------------- 100%

                        x   -------------------   20%

                        x = (20 x 25) / 100

                        x = 500 / 100

                        x = $5

Price after the discount = $25 - $5

                                       = $20

2.- Calculate the price after taxes

                     $20 ---------------------- 100%

                         x  -----------------------   5%

                       x = (5 x 20) / 100

                       x = 100 / 100

                       x = $1

Final price = $20 + $1

                = $21
