Answer:
8yz+xy
like terms and then solve it
<span> RdΘ/dt = v </span>
<span>dΘ/dt = (1/3)/20 = 1/60 rad/sec </span>
<span>5(1/60 ) = 5/60 cm/sec = 1/12 cm/sec </span>
<span>Angular Speed = dΘ/dt = 1/60 rad/sec </span>
<span>Linear Speed = RdΘ/dt = 1/12 cm/sec </span>
Answer:if there are 7 HS students for every 2 MS students and there are 18 MS students...
18/2 = 9
9(7) = 63
So, there are 18 + 63 = 81 total students.
Since we had 9 parts last year also (1:8), 81/9 = 9 students are in each part. 8 students in each part are HS and one is MS.
8(9) = 72 HS students last year.
72 - 63 = 9 fewer HS students than last year.
Hope this helps!
3(2x)=4x+4
do the bracket first
(3)(2x)= 6x
6x= 4x+4
move 4x to the other side
sign changes from +4x to -4x
6x-4x=4x-4x+4
6x-4x= 4
2x= 4
divide by 2
2x/2=4/2
x=2
Answer: x= 2
