Answer:
Cost of the binder = $5
Cost of the highlighter = $2.5
Cost of the folder = $2
Step-by-step explanation:
Let
Cost of the binder = x
Cost of the highlighter = 1/2x
Cost of the folder = x - 3
Total cost = $9.50
Total cost = Cost of the binder + Cost of the highlighter + Cost of the folder
9.50 = (x) + (1/2x) + (x-3)
9.50 = x + 1/2x + x - 3
9.50 + 3 = x + 1/2x + x
12.50 = 2x + 1/2x
12.50 = 2 1/2x
12.50 = 5/2x
x = 12.50 ÷ 5/2
= 12.50 × 2/5
= 25/5
x = $5
Cost of the binder = x = $5
Cost of the highlighter = 1/2x = 1/2*6 = $2.5
Cost of the folder = x - 3
= 5 - 3 = $2
So first you want to do the cost of each foot times the number of feet 112 * $1.59 = $178.08
Then do the subtraction $200.00 - $178.08 = $21.92
Therefore, the answer is C
Answer:
x = -8
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
-1x = -8 - 2x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Simplify: -x = -8 - 2x
- Add 2x on both sides: x = -8
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: -1(-8) = -8 - 2(-8)
- Multiply: 8 = -8 + 16
- Add: 8 = 8
Answer:
The answer would be that All the powers have a value if 1 because the exponent is zero.
Step-by-step explanation:
Use the exponent rule to help you
X=3. Just divide 12 by 4 thus giving you 3.
