Explanation : Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
1.) X=2, 2/2=1, Y=1
2.) X=6, 6/2=3, Y=3
3.) X=10, 10/2=5, Y=5
I hope this helps! :)
Answer:
Step-by-step explanation:
Multiply $120 (cost of haircut) X .18 (18% in decimal form) to get the tip amt.
120 X .18 = 21.60
Now add $120 (haircut) + 21.60 (tip) together to get the total amt. she paid.
120 + 21.60 = $131.60
Carla gave her stylist $131.60 total
Answer:
Teo is 11 years old and Richard is 26 years old.
Step-by-step explanation:
Let R be the age of Richard and T be the age of Teo.
<u><em>First set up the equations:</em></u>
The combined age of Teo and Richard is 37:
R+T=37
Richard is four years old than twice Teo's age:
R=2T+4
<u><em>Then, solve the equations:</em></u>
Substitute (2) to (1) and solve for T:
(2T+4)+T=37
3T=11
T=11
Solve for R using (2):
R=2(11)+4
R=22+4
R=26
