What is the solution for the systems of equations below?

1 answer:

3 0

Use elimination
3x + 4y = -2
2x - 4y = -8
Add both equations
5x = -10, x = -2
3(-2) + 4y = -2
-6 + 4y = -2
4y = 4, y = 1
Solution: x = -2, y = 1

V125BC [204]

Answer:

<u>24 pieces</u> of fruits are use to make 2 fruit salads.

Step-by-step explanation:

Given:

Ken uses 6 apples and 2 bananas to make a fruit salad. He put twice as many oranges as bananas in the salad.

Now, to find the number of pieces of fruit Ken will use to make 2 fruit salads.

So, pieces of fruits use to make a salad are:

Apples = 6.

Bananas = 2.

Oranges = twice of bananas = 2×2=4.

So, total pieces of fruits to make a salad = $6+2+4=12.$

Now, total pieces of fruits to make 2 fruit salads:

$(6+2+4)\times 2$

$=12\times 2$

$=24.$

Therefore, 24 pieces of fruits are use to make 2 fruit salads.
