Hope this helps <3.
3p + 2n = 8.25 ....multiply by 2
2p + 3n = 8 .........multiply by -3
-------------------
6p + 4n = 16.5 (result of multiplying by 2)
-6p - 9n = - 24 (result of multiplying by -3)
-------------------add
-5n = - 7.5
n = -7.5 / -5
n = 1.50 .............notebooks cost 1.50 each
2p + 3n = 8
2p + 3(1.50) = 8
2p + 4.50 = 8
2p = 8 - 4.50
2p = 3.50
p = 3.50/2
p = 1.75......pens cost 1.75 each
so 2 pens and 2 notebooks cost : 2(1.75) + 2(1.50) = $ 6.50 <==
if she can elaborate and mach the speed of all nearby cars then have it equal to the velocity of the car in front of her
Step-by-step explanation:
Answer:
A) N + Q = 9
B) .05 N + .25 Q = 1.45
Multiplying A) by -.25 we get
A) -.25 N -.25Q = -2.25 then adding B)
B) .05 N + .25 Q = 1.45
-.2N = -.80
