Answer:
for m∠SRQ x = 3
for m∠QRP x = 5
Step-by-step explanation:
1. 6x +2. 6 is being multiplied by a number so to find that number we do teh opposite
6x/2 = 3
drop the x then u have x = 3
2. 2x+10. 2 is being muliplied by a number so to find that number we do teh opposite
10/2x = 5
drop the x then u have x = 5
So you have a 50% chance to have a boy vs a girl (1/2). If you want 3 children, that would be 1/3*1/2= 1/6 or 16.67% chance

Answer:
1. 3sqrt(2)
Choice C
2. 2sqrt(3)
Choice D
Step-by-step explanation:
1. sqrt(x+3)
sqrt(15+3)
sqrt(18)
sqrt(9*2)
sqrt(9)sqrt(2)
3sqrt(2)
Choice C
2. 6/sqrt(x)
6/sqrt(3)
no radicals in the denominator, multiply by 1 in the form of the radical
6/sqrt(3) * sqrt(3)/sqrt(3)
6sqrt(3)/ (sqrt(3)*sqrt(3))
6sqrt(3)/3
2sqrt(3)
Choice D
