Answer:
5x+6y=60
Step-by-step explanation:
x= $5 per pound of second type of seed
y=$6 per pound of first types of seed
-32 + 8x - 8 = 6x + 12
8x - 40 = 6x + 12
8x = 6x + 12 + 40
8x = 6x + 52
8x - 6x = 52
2x = 52
x = 52/2
x = 26
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Rational numbers are those numbers which can be written as p/q form or it must be non terminating but recurring number.
-13 can be written as p/q form as 
is a rational number because of its form.
81 can be written in p/q form as 
But √2 is non terminating and non recurring number.
Hence, √2 is not a rational number.
Therefore, Option 'A' is correct.
Answer:
See below.
Step-by-step explanation:
1)
So we have:

This can be interpreted as:
"There exists a natural number <em>x</em> and an integer <em>y</em> such that x² is equal to y²."
2)
So we want even numbers are in the set of integers.

This is interpreted as:
"The set of even numbers (2n such that n is an integer) is in the set of integers"
Answer:
The questions asks you to write a number in which the digit "5" is one-tenth the value of the number 5 in 89.547. You are looking for a number that is one-tenth of 0.5. Remember, one-tenth equals 1/10 which equals 0.1. One-tenth of 0.5 equals 0.1 multiplied by 0.5 which equals 0.05.
