Answer:
(x,y)=(4/569),(228/569)
Step-by-step explanation:
multiply both ides by -18
eliminate one variable by adding the equations
divide both sides by -19346
sub the value of x into the equation
solve the equation
<span>let m is the angle s be the supplement and c be the compliment
s=10+3c
180-m=10+3(90-m)
180-m = 10 +270 -3m
-100 = -2m
m = 50 </span>

Answer:
x = 4/7
Step-by-step explanation:
5/3 x = 20/21
Multiply by 3/5 on each side to isolate x
3/5 *5/3 x = 20/21 * 3/5
x = 20/21 * 3/5
Rewriting the right hand side
x = 20/5 * 3/21
x =4 * 1/7
x = 4/7
There are different formulas for calculating the two types of compound events: Say A and B are two events, then for mutually exclusive events: P(A or B) = P (A) + P(B). For mutually inclusive events, P (A or B) = P(A) + P(B) - P(A and B).
