Answer:
x=8
Step-by-step explanation:
2x+7 = 23
2x=16
x=8
Distance^2 = 8^2 + 15^2
Distance^2 = 64 + 225
Distance^2 = 289
Distance = 17 kilometers
The correct option regarding whether the sum of a rational number and an irrational number is always irrational is given by:
Yes. The claim is correct because √ 16 + π = 4 + π , and 4 + π is an irrational number.
<h3>What are rational and irrational numbers?</h3>
- Rational numbers are numbers that can be represented by fractions, such as terminating decimals.
- Irrational numbers are numbers that cannot be represented by fractions, such as non-terminating decimals and non-exact roots.
The sum of a terminating decimal with a non-terminating decimal always results in a non terminating decimal, that is, the sum of a rational number with an irrational number is always irrational, and the correct option is given by:
Yes. The claim is correct because √ 16 + π = 4 + π , and 4 + π is an irrational number.

Answer: c 12 pounds of the $5.50-per-pound coffee, 8 pounds of the $9.20-per-pound coffee
Step-by-step explanation:
Let x = Number of pound of first king.
y= Number of pound of second kind.
As per given , we have
substitute value of y from (i) in (ii), we get
Put this in (i), we get y= 20-8 = 12
Hence, he should blend 12 pounds of the $5.50-per-pound coffee, 8 pounds of the $9.20-per-pound coffee.
So the correct option is c.
