Answer:
5/3
Step-by-step explanation:
19x=3+4(x+6)-2
19x=3+4x+24-2
19x-4x=3+24-2
15x=27-2
15x=25
x=25/15
simplify
x=5/3
Answer:
New cars sold = 20,
Used cars sold = 25
Cars serviced = 290
Step-by-step explanation:
In a month they sold fifteen less used cars than twice the number of new cars.
Lets say 'x' number of new cars were sold, then:
The number of used car sold is:

In the same month they serviced fifty more than twelve times the number of new cars sold. So the number of cars serviced is:

Altogether they sold or serviced 335 cars, so the sum of all the cars sold and serviced should be 335:

Solving for 'x' we get:




Therefore, the number of new cars sold in that month is 20.
Number of used car sold 
Number of cars serviced 
We can also cross check by summing them up:

Answer:
m∠N = 85°
Step-by-step explanation:
<u>Properties of a parallelogram</u>
- opposite sides are parallel and equal in length
- opposite angles are equal
- interior angles that lie on the same side of the transversal are supplementary - their sum is 180°
Therefore,
m∠M + m∠N = 180°
⇒ 95° + m∠N = 180°
⇒ m∠N = 180° - 95°
⇒ m∠N = 85°
--------------------------------------------------------------------------------------
<u>Additional calculations</u>
m∠M = m∠P = 95°
m∠N = m∠L = 85°
MN = LP
ML = NP
Answer:
The function a^x is increasing, while a^-x is decreasing.
Step-by-step explanation:
The reason for this is the negative. a^x is increasing due to the positive power, while a^-x is decreasing to the negative power.
