Tan(3x) = 1
3x = arctan(1) = pi/4, -3pi/4
x = (pi/4)/3 = pi/12 or (-3pi/4)/3 = -pi/4
Therefore, x = pi/12 or -pi/4
We can represent the Rambutan as x-4+2x or 3x-4 because it costs 2x dollars more than the Dragonfruit.
We can represent the Starfruit as 3x-4-5 or 3x-9 because it costs 5 dollars less than the Rambutan
Therefore the overall equation would be:
(3x-4)+2(3x-9)+3(x-4) (distribute)
3x-4+6x-18+3x-12 (combine like terms)
12x-34
Hope this helps

Step-by-step explanation:
<u>Step 1: Define</u>
-3y + 14 + y = 12
<u>Step 2: Solve for </u><em><u>y</u></em>
- Combine like terms [Addition]: -2y + 14 = 12
- [Subtraction Property of Equality] Subtract 14 on both sides: -2y = -2
- [Division Property of Equality] Divide -2 on both sides: y = 1
16 or 4^2
This is really saying is 1/(1/4^2)
Answer:
See below.
Step-by-step explanation:
This is focusing on the order of operations.
PEMDAS = Parenthesis, exponents, multiplication, division, addition, subtraction.
40 ÷ [(18 - 9) - (13 - 12)]
40 ÷ [9 - 1]
40 ÷ 8
5
[(13 - 9) · 3] + [(14 - 8) · 2]
[4 · 3] + [6 · 2]
12 + 12
24
