Answer:
The answer to your question is w = 1.2
Step-by-step explanation:
Data
Equation 7(w + 2) + 0.5w = 5
Expand 7w + 14 + 0.5w = 5
Simplify like terms (7w + 0.5w) + 14 = 5
7.5w + 14 = 5
Subtract 14 in both sides
7.5w + 14 - 14 = 4 - 15
Simplify
7.5w = - 9
Divide both side by 7.5 7.5/7.5w = 9/7.5
Simplify
w = 1.2
We know that :
⊕ Sum of the interior angles in a Pentagon should be equal to 540°
⇒ x° + (2x)° + (2x)° + 90° + 90° = 540°
⇒ (5x)° = 540° - 180°
⇒ (5x)° = 360°

⇒ x° = 72°
Answer:
x=4/15
Step-by-step explanation:
first you need to make common denominators for 1/5 and 1/3
the common denominator is 15
5*3=15, 3*5=15. 1*3=3, 1*5=5
new equation:3x-3/15=x+5/15
now subtract x from both sides: 3x-3/15=x+5/15
-x -x
2x-3/15=5/15
now you can add 3/15 to 5/15
2x=8/15
now for the last step, divide by 2 because there are 2 x's
2x/2=x 8/15 /2=4/15
x=4/15
Quoteint of powers
(x^m)/(x^n)=x^(m-n)
we know that 8=x^3
so
(2^5)/8=2^2 can be rewritten as
(2^5)/(2^3)=2^2
and 5-3=2 so it's true
answer is
third one
by simplifieng 8 to 2^3 to make both powers base two, and subtraction the exponents
