X+ y + z = -3<br> 3y - Z = 4<br> 2x- y - 2z = -5
snow_lady [41]

Answer:

  • (-3, 1, -1)

Step-by-step explanation:

  • x + y + z = -3  --> (1)
  • 3y - z = 4   --> (2)
  • 2x - y - 2z = -5 --> (3)

<u>Add up (1) and (2)</u>

  • x + 3y + y + z - z = -3 + 4 ⇒ x + 4y = 1  --> (4)

<u>Double (2) and subtract from (3)</u>

  • 2x - y - 2z - 2(3y - z) = -5 - 2(4) ⇒ 2x - y - 2z - 6y + 2z = -5 - 8
  • 2x - 7y = -13 --> (5)

<u>Double (4) and subtract (5)</u>

  • 2(x + 4y) - 2x + 7y = 2 + 13 ⇒ 2x + 8y - 2x + 7y = 15 ⇒ 15y = 15 ⇒ y = 1

<u>Finding x</u>

  • x + 4(1) = 1 ⇒ x = 1 - 4  ⇒ x = -3

<u>Finding z</u>

  • -3 + 1 + z = -3 ⇒ z = -1

<u>So the answer is: </u>

  • (-3, 1, -1)

One batch of walnut muffins uses 1 1/3 cups of walnuts. How many cups of walnuts are needed to make 3 3/4 batches of muffins?
dusya [7]

Answer:

5 cups of walnuts are needed.

Step-by-step explanation:

This question can be solved using a rule of three.

One batch of walnut muffins uses 1 1/3 cups of walnuts.

So one batch of walnut muffins uses 1 + \frac{1}{3} = \frac{4}{3} cups of walnuts.

How many cups of walnuts are needed to make 3 3/4 batches of muffins?

How many cups are required for 3 + \frac{3}{4} = \frac{15}{4} batches.

1 batch - (4/3) cups

(15/4) batches - x cups

x = \frac{4}{3} \times \frac{15}{4} = \frac{60}{12} = 5

5 cups of walnuts are needed.
