Answer:
A
Step-by-step explanation:
To find how much 3/4 of a number is, multiply 3.4 by the number. Since the book is 7/8 inches thick, Brenden read 3/4 * 7/8.
To multiply fractions, multiply straight across numerator and denominator.
3/4 * 7/8 = 3*7/ 4*8 = 21/32
Answer:
x =35.
Step-by-step explanation:
x / 20 = 14 / 8
Cross multiply:
8x = 20*14
8x = 280
x = 35.
Answer: x (x - 1)
Step-by-step explanation:
x (x - 1)
As the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1
As per the question statement, we are given a new mathematical operation a△b=a^2-b/b-a^2 and we are supposed to find the value of 4△3 using the same operation.
Given, a△b=a^2-b/b-a^2
now 4△3 = (4^2-3) / (3-4^2)
4△3 = (16-3) / (3-16)
4△3 = 13 / -13
4△3 = -1
Hence, as the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1.
