Answer:
y = x + 64
Step-by-step explanation:
The total # of books she has read in the first row is 67, the difference between 67 and 3 is 64.
As you look at the other rows, you see as you subtract 64, you get the same number of additional books read.
Example: 67-64=3
77-64=13
87-64=23
97-64=33
x represents the number of additional books so if you add 64 to x you get the total number which is why the answer is the 3rd option
Answer:
351
Step-by-step explanation:
27C2 = 27! / 2! × (27-2)!
= 27×26×25! / 2×1 × 25!
= 27×26 /2
= 27×13
= 351
Answer:
a = -1 , b = 4 , c = 3 , d = 1
Step-by-step explanation:
Given:

The right hand side = (-xy)³ (xz) = (-1)³ x³ y³ x z = (-1) x⁴ y³ z
Comparing the right hand side with the left hand side
∴ a = -1
∴ b = 4
∴ c = 3
∴ d = 1
