2x+3x+x+9 = ??
5x+x+9 = ??
6x+9= ??
6x = -9 ---- subtract 9 on both sides
x = - 3/2 ----- didvide by 6 on both sides, simplify
Step-by-step explanation:
a. (0.60x + 0.70y)- 50 = 10
<=> 0.60x + 0.70y = 60
b. (x+y) = 5(x-y)
x+y=5x-5y
<=> 4x - 6y = 0
9) 216 in
10) 12 yd
11) 3.75 ft
12) 30 yd
13) 8 ft
14) 26 ft
The answer is 58 pretty sure
The equation in the form of the given expression is (0)² + (1)² = 1
<h3>Trigonometry identity</h3>
According to some of the trigonometry identity
sin 0 = 0
cos 0 1
Given the expression below
sin^2 0+cos^2 0=1
This can also be expressed as:
(sin0)² + (cos0)² = 1
Substitute
(0)² + (1)² = 1
Hence the equation in the form of the given expression is (0)² + (1)² = 1
