HELP WILL REWARD
Phantasy [73]

Answer:

We set up our equations:

 

35x+40y = 1850        eq1

x+y = 50                   eq2

 

Substituting eq 2 into eq 1,

 

35x+40(50-x) = 1850

35x+2000-40x = 1850

-5x+2000 = 1850

-5x = -150

  x = 30

 

Substitute value of x into eq 2.

 

x+y = 50

30+y = 50

     y = 20

 

Car 1 consumes 30 gallons of gas.

Car 2 consumes 20 gallons of gas.

hope this helps

Sin(3x-16)=cos(4x-6) x=?
lapo4ka [179]
sin(3x-16)=cos(4x-6) \\  sin(3x-16)=sin( \frac{ \pi }{2} -(4x-6)) \\ 3x-16=\frac{ \pi }{2} -(4x-6)
3x-16=\frac{ \pi }{2} -4x+6
then :
<u />3x-16=2k \pi +(\frac{ \pi }{2} -4x+6) \\ 7x=2k \pi +\frac{ \pi }{2}+22 \\ x= \frac{2k \pi}{7}  +\frac{ \pi }{14}+ \frac{22}{7}
and \\ 3x-16=2k \pi + \pi -(\frac{ \pi }{2} -4x+6) \\ 3x-16=2k \pi + \pi -\frac{ \pi }{2} +4x-6 \\ -x=2k \pi + \frac{ \pi }{2}+10 \\ x=-2k \pi - \frac{ \pi }{2}-10
