Answer:
The required ratio is 9 : 61
Step-by-step explanation:
Given,
$72 for 488 photos,
That is, the price of 488 photos = 72 dollars,
So, the ratio of price of photos and number of photos = 
∵ HCF(72, 488) = 8,
Thus, the ratio of price of photos and number of photos = 
= 
34. x - 3 = 8x + 4
-3 - 4 = 8x - x
-7 = 7x
-7/7 = x
-1 = x
y = x - 3
y = -1 - 3
y = -4
solution is (-1,-4)
===================
35. -6 = -x - 2y
x = -2y + 6
2 + 5x = -2y
2 + 5(-2y + 6) = -2y
2 - 10y + 30 = -2y
32 = -2y + 10y
32 = 8y
32/8 = y
4 = y
2 + 5x = -2y
2 + 5x = -2(4)
2 + 5x = -8
5x = -8 - 2
5x = -10
x = -10/5
x = -2
solution is (-2,4)
==================
36. 4x + 6y = 2000
x + y = 410
==================
37. 4x + 6y = 2000
x + y = 410......multiply by -6
----------------------
4x + 6y = 2000
-6x - 6y = - 2460 (result of multiplying by -6)
--------------------add
-2x = - 460
x = -460/-2
x = 230 <=== tickets in advance
Answer: 1st box- subtracting 8 from both sides
2nd box- -8
Step-by-step explanation:
SR is parallel to PQ so has the same slope as PQ, which is 2/3
