Answer:
x=1
Step-by-step explanation:
6-3x=5x-10x+8=
move all terms to the left:
6-3x-(5x-10x+8)=0
add all the numbers together, and all the variables
-3x-(-5x+8)+6=0
get rid of parentheses
-3x+5x-8+6=0
add all the numbers together, and all the variables
2x-2=0
move all terms containing x to the left, all other terms to the right
2x=2
x=2/2
x=1
Answer:
the movie had played 112.53 minutes
Step-by-step explanation:
x is equal to 112.53
Multiplying through by 8 we get
2x + 8 = 3x
8 = 3x - 2x
x = 8 (answer)
Answer:
A = 137° a = 14 cm
B = 26° b = 9 cm
C = 17° c = 6 cm
Step-by-step explanation:
<u>Cosine rule</u>
where:
- c is the side opposite angle C
- a and b are the sides with C as the included angle.
Given:
- a = 14 cm
- b = 9 cm
- c = 6 cm
<u>Sine Rule</u>
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Sum of interior angles of a triangle = 180°
⇒ ∠A + ∠B + ∠C = 180°
⇒ ∠A = 180° - 25.997...° - 16.9912...°
⇒ ∠A = 137.0107361...°
1/4 times 16x is 4x
1/4 times 4 is 1
4x minus 9x is -5x
So, 1/4 (16x+4)-9x is -5x+1
-5 times x is -5x
-5 times 1 is -5
So,-5 (x+1) is -5x-5
Therefore they are not equivalent
