Answer:
$8
Step-by-step explanation:
48 = 2×2×2×2×3
56 = 2×2×2×7
Max cost could be 2×2×2 = 8
The most the books could cost is 8 bucks.
To find this answer you mostly have to find unit rate.
Or you could subtract 56-48 to get your answer because each book cost the same so 8+48 +56
Hope this helps.
Answer: 45/53
CAH is Adjacent over Hypotenuse
2x2 = 4 +15 =19+134= 153
I think that is the first one
y = -12x - 1
y = 14x - 4
-12x - 1 = 14x - 4
-1 + 4 = 14x + 12x
3 = 26x
3/26 = x
y = 14(3/26) - 4
y = 42/26 - 4
y = 42/26 - 104/26
y = - 62/26 reduces to - 31/13
solution : x = 3/26 and y = -31/13 or (3/26,-31/13)
the answer is 980304
