Answer:
Two consecutive integers are of the form
x and x + 1
Their product is equal to 56
x(x + 1) = 56
Solve and find the two numbers x and x + 1. The above equation may be written as follows
x2 + x - 56 = 0
Factor and solve
(x - 7)(x + 8) = 0
solutions: x = 7 , x = -8
x= - 8 is not valid since the number sought must be positive. Hence
x = 7 and x + 1 = 8 are the two consecutive numbers.
Step-by-step explanation:
Answer:
1/7
Step-by-step explanation:
Another word for multiplicative inverse is reciprocal
It is the number that when multiplied by the original number gives you one
7 * x = 1
Divide by 7
7x/7 = 1/7
x = 1/7
The multiplicative inverse of 7 is 1/7
