Cost of 2 1/2 yards= $15
cost of  1 yard=?
cost of one yard= 15/(2 1/2)
=15/5/2
=15/5*2
=3*2
=$ 6
so the cost of fabric for one yard will be $6

12x-6>14x-2 graph it
Jet001 [13]

Answer: 12x-6=14x-2

We move all terms to the left:

12x-6-(14x-2)=0

We get rid of parentheses

12x-14x+2-6=0

We add all the numbers together, and all the variables

-2x-4=0

We move all terms containing x to the left, all other terms to the right

-2x=4

x=4/-2

x=-2

At the fast food restaurant, four cheeseburgers and five small fries have a total of 2,310 calories. Three cheeseburgers and two
Svetlanka [38]

<u><em>Answer:</em></u> <em><u>290 calories in a cheeseburger and 230 calories in fries.</u></em>

<em><u>x = calories in a cheeseburger</u></em>

<em><u>y =  calories in an order of small fries</u></em>

<em><u>Four cheeseburgers and five small fries have 2,310 calories. Therefore</u></em>

<em><u>4x + 5y = 2310       (1)</u></em>

<em><u>Three cheeseburgers and two small fries have 1,330 calories. Therefore</u></em>

<em><u>3x + 2y = 1330        (2)</u></em>

<em><u>Equations (1) and (2) model the given situation.</u></em>

<em><u>To solve, multiply (1) by 2, and multiply (2) by 5 to obtain</u></em>

<em><u>  8x + 10y = 4620          (3)</u></em>

<em><u>15x + 10y = 6650          (4)</u></em>

<em><u>Subtract (3) from (4).</u></em>

<em><u>7x = 2030</u></em>

<em><u>x = 290</u></em>

<em><u>From (1), obtain</u></em>

<em><u>5y = 2310 - 4*290 = 1150</u></em>

<em><u>y = 230</u></em>

<em><u> x = 290, y = 23</u></em>

<u><em>Hope this helps!</em></u>

Find the missing angle.
alex41 [277]

Answer:

x = 63°

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Geometry</u>

  • All angles in a triangle add up to 180°

Step-by-step explanation:

<u>Step 1: Set up equation</u>

x + 94° + 23° = 180°

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    x + 117° = 180°
  2. Subtract 117° on both sides:        x = 63°
