Please help me to find the answer Y=2X 3X+4Y=22 Y=2X 3X+4Y=22 ​
RSB [31]
<h3>System of equations.</h3>

\left\{\begin{array}{ccc}y=2x&(1)\\3x+4y=22&(2)\end{array}\right

Put (1) to (2):

3x+4(2x)=22\\3x+8x=22\\11x=22\qquad|\text{divide both sides by 11}\\\boxed{x=2}

Substitute the value of x to (1):

y=2\cdot2\\\boxed{y=4}

Solution:

\huge\boxed{\left\{\begin{array}{ccc}x=2\\y=4\end{array}\right}

for a party. 10 friends are buying 100 cups,100 plates a punchbowl, and 200 ballons.if the friends share the cost equally ,how m
andrezito [222]

Answer:

Every friend would contribute 10% of total cost.

Step-by-step explanation:

As total shopping of 10 friends contains:

  • 100 cups
  • 100 plates
  • One Punchbowl
  • 200 balloons

As you have not specified the typical prices of buying things, so I am assuming that each part of every entity costs 1 unit. For example, one cup costs 1 unit, one plate costs 1 unit, one punchbowl costs 1 unit, and 1 balloon costs 1 unit.

<em>Note: Just assume, that 1 unit could be any currency, like 1 unit means one US dollar etc.</em>

It means,

  • 100 cups costs 100 units
  • 100 plates cost 100 units
  • A punchbowl costs 1 unit
  • 200 balloons cost 200 units

So, total cost of 100 cups, 100 plates, one Punchbowl, and 200 balloons:

100 + 100 + 1 + 200 = 401 units

As

Total cost of all shopping = 401 units

Total friends = 10

As the friends share the cost equally. Hence, just divide the total cost by total number of friends to establish the contribution of each friend.

Contribution of each friend = Total cost all shopping / Total friends

Contribution of each friend = 401/10 ⇒ 40.1 units

So, each friend would contribute the cost of 40.1 units.

<em>In other words, every friend would contribute 10% as 10% of 401 = 40.1 units.</em>

<em>Keywords: cost, share</em>

Arrange the steps in the correct order to express cos3x in terms of cosx
ziro4ka [17]

The correct order to express cos3x in terms of cosx is; As shown in steps 1 to 9 below.

<h3>How to simplify Trigonometric Identities?</h3>

The steps to simplify the trigonometric identities cos 3x in terms of cos x are as follows;

Step 1; cos x = cos(2x + x)

Step 2; cos(2x) cosx - sin(2x) sinx

Step 3; 1 - 2sin^2x(cosx) -(2sinxcosx)sinx

Step 4; cosx - 2sin²x cosx - 2sin²x cosx

Step 5; cosx - 4sin²x cosx

Step 6; cosx( 1 - 4sin²x)

Step 7; cosx{1 - 4(1 - cos²x)}

Step 8; cosx{-3 + 4cos²x}

Step 9; 4cos³x - 3cosx
