- Order of Operations: BPEMDAS
<u>Alg I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
4x = 8y
2x + 5y = 27
<u>Step 2: Rewrite systems</u>
x = 2y
2x + 5y = 27
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute: 2(2y) + 5y = 27
- Multiply: 4y + 5y = 27
- Combine like terms: 9y = 27
- Isolate <em>y</em>: y = 3
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Plug in y into an original equation to find x.</em>
- Substitute: 4x = 8(3)
- Multiply: 4x = 24
- Isolate <em>x</em>: x = 6
Add both distances to find the total distance between them: 3447+86=3533 ft.
Answer:
Because you are looking for square inches of wrapping paper, you are looking for the surface area of the box. A three-dimensional box has a top and bottom that are the same size, a front and back that are the same size, and 2 sides that are the same size...or SA = 2(top/bottom area) + 2(front/back area) + 2(side/side area). Our equation fills in nicely like this:
SA = 2(6 * 14) + 2(6 * 8) + 2(14 * 8)
SA = 2(84) + 2(48) + 2(112)
SA = 168 + 96 + 224
SA = 488 square inches of paper to wrap the box.
