9.) <span>1/2(4x-6)=11
</span>Multiply 4 and -6 by 1/2
2x-3=11
Add 3 to both sides
2x=14
Divide 14 by 2
Final Answer: x=7
10.) 2/3(6x-9)=-34
Multiply 6 and -9 by 2/3
4x-6=-34
Add 6 to both sides
4x=-34
Divide -34 by 4
Final Answer: x=-8.5
Step-by-step explanation:
1. f+15<6
= f<6-15
f < -9
2. f+12 >16
f >16-12
f > 4
So, first you subtract 10 from 38 which gives three times of the money spent for the movie. Then you divide 3 from it to give you the answer.
38-10 = 28
28/3 = 9.37 dollars
Let's calculate the hypotenuse of this right triangle:
(Hypotenuse)² = 8² + 15² = 289, Hypotenuse = √289 = 17.
a) If Ф is facing the largest side (15), then sinФ = opposite side / hypotenuse
and sinФ = 15/17 = 0.8823
b) If Ф is facing the smallest side (8), then sinФ = opposite side / hypotenuse
and sinФ = 8/17 = 0.4705
