Add up the same sides of both equations to eliminate <em>x</em> :
(<em>x</em> - 2<em>y</em>) + (-<em>x</em> + 3<em>y</em>) = 8 + (-5)
(<em>x</em> - <em>x</em>) + (-2<em>y</em> + 3<em>y</em>) = 8 - 5
<em>y</em> = 3
Then
<em>x</em> - 2<em>y</em> = <em>x</em> - 6 = 8 → <em>x</em> = 14
180 = 2n + 128
2n = 52
n = 26°
180 - 128 = 52
90 + 52 + m = 180
142 + m = 180
m = 38°
Answer: n = 26° and m = 38°
Answer:11/29
Step-by-step explanation:
The numerator is alredy given as 11 students play both an instrument and a sport. Denominator is how many students in the class which is 29.
Distribute -10
-10n - 50 = 40
Add 50 to both sides
-50 + 50 would cancel
- 50 + 40 = -10
Divide by -10
-10/-10 = 1
N=1
Answer:
2/3
Step-by-step explanation:
Simplify the numerator
(2x) ^3 = 8 x^3
8x^3 * 3x = 24 x^4
Simplify the denominator
(6x^2) ^2 = 36 x^4
Simplify the fraction
24x^4/ 36 x^4 =
24/36 = 2/3
x^4/x^4 =1
The fraction is 2/3 when x does not equal 0
