Answer:
x = 7
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-Step Explanation:
Step 1: Define
5(x - 3) = 2(x + 3)
Step 2: Solve for x
1. Distribute: 5x - 15 = 2x + 6
2. Subtract 2x on both sides: 3x - 15 = 6
3. Add 15 on both sides: 3x = 21
4. Divide both sides by 3: x = 7
Answer:
Step-by-step explanation:
Distribute:
Y+-3+(-2)(x)+(-2)(1)
Y+-3+-2x+-2
Combine like terms
Y+-3+-2×+2
(-2×)+(y)+(-3+-2)
-2x+y+-5
Answer:
5sqrt(5) = q
-5sqrt(5) = q
Step-by-step explanation:
f(q) = q^2 -125
To find the roots set the equation equal to zero
0 = q^2 -125
Add 125 to each side
125 = q^2 -125+125
125 = q^2
Take the square root of each side
±sqrt(125) = sqrt(q^2)
±sqrt( 5*25) = q
±sqrt( 25)* sqrt(5) = q
±5* sqrt(5) = q
±5sqrt(5) = q
3 + 1/9 = 27/9 + 1/9 = 28/9
2 + 2/5 = 10/5 + 2/5 = 12/5
------------------------------------------
So:
[3+(1/9)]/[2+(2/5)]
=(28/9)/(12/5)
=(28/9)*(5/12)
=140/108 = 70/54 = 35/27

<em><u>Answer</u></em>:
<h2>The strange number here is √48</h2>
<em><u>Step-by-step explanation:</u></em>
√(48)=6,928203230276...
so, √(48) is an irrational number and all the 3 others are rationals.
