Answer:C
Step-by-step explanation:
6(x+7)=5(x-7)+x
⇔6x+42=5x-35+x
⇔6x-5x-x=-35-42
⇔0x=-77
Let a be the number of trumpet players
Let b be the number of saxophone players
---------------------
(1) a = b-10
(2) b =3a
----------------
Substitute
(2) into (1)
(1) a =3a-10
(1) 2a =10
(1) a = 5and
(2) b = 3(5)(2)
b = 15
------------------
There are 5 trumpet players and 15 saxophone player
recall from the previous posting, the sum of all interior angles in a triangle is 180°.
so the third one will be 180° - 118.6° - 42.3°.
<span>Let us suppose that two particles A and B start moving. Particle A starts moving at time t = 0 and velocity v. At time t, particle B has twice acceleration, half velocity and same position as the particle A has at time t=0. </span>
So, position of particle B depends on time
<span>The equation of motion can be written as:</span>
