1 answer:
yuradex [85]3 years ago
6 0

Step-by-step explanation:

y = 2x - 24 \\ 4x = 3y \\ 2x = 1.5y \\ y = 1.5y - 24 \\ y - 1.5y =  - 24 \\ 0.5y = 24 \\ y = 48 \\ x =  \frac{3y}{4}  =  \frac{3 \times 48}{4}  = 36

x= apples =36 cents

y= pears =48 cents

kompoz [17]

Answer:

Distance between the two planes after 1 hour = 410 miles

Step-by-step explanation:

Given - A plane leaves and flies due north at 280 miles per hour. At

            the same time another plane takes off from the same airport

            and flies due east at a speed of 300 miles per hour.

To find - What is the distance between the two planes after 1 hour ?

Proof -

Given that , Plane 1 flies due north at a speed of 280 miles per hour.

So,

Total distance traveled in 1 hour = 280 miles

Also,

Plane 2 flies due east at a speed of 300 miles per hour.

So,

Total distance traveled in 1 hour = 300 miles.

The diagram is as follows :

Now,

We have to find the distance after 1 hour i.e. AC

In Triangle ABC ,

By using Pythagoras theorem, we get

AC² = BC² + AB²

⇒AC² = (300)² + (280)²

⇒AC² = 90,000 + 78,400

⇒AC² = 168,400

⇒AC = √168,400

⇒AC = 410.366 ≈ 410

∴ we get

Distance between the two planes after 1 hour = 410 miles

4x+2y=18

-2(2x+3y=15)=-4x-6y=-30

4x+2y=18

-4x-6y=-30

-4y=-12

y=3

2x+3(3)=15

2x+9=15

2x=6

x=3
