Which equation is equivalent to 4.5 = 2a?

Answer:

√2 and √3

Good Luck!!!

Final answer:

A pair of irrational numbers whose sum is irrational does not practically exist. The sum of two irrational numbers can be either rational or irrational, and this solely depends on the numbers being added together.

Explanation:

The irrational numbers can be defined as any real number that is not a rational number. However, the sum of two irrational numbers is not always irrational. It could be rational or irrational depending on the numbers you're adding. However, you've asked for a case where the sum is also irrational. Let's consider two irrational numbers √2 and -√2. √2 is irrational. Likewise, -√2 is also irrational. However, when added (√2 - √2), they result in 0 which is not irrational. Therefore, it's near impossible to find two irrational numbers whose sum is also irrational.

Answer:

The correct option is 1.

Step-by-step explanation:

The given set of equations is

Equation A: c = 2d + 1

Equation B: c = 3d + 5

Using equation A and equation B, equate the value of c.

The value of d is -4. So the value of c is

The equation 2d+1=3d+5 is used to find the solution to the set of equations, therefore the correct option is 1.

Answer:

2.4

Step-by-step explanation:

• √(x² +49) = x + 5
• (√(x² +49) )²= (x + 5)²       ⇒  square of both sides
• x² + 49 = x² + 10x + 25     ⇒  simplifying, x² get cancelled
• 10x = 49 -25
• 10x = 24
• x= 24/10
• x= 2.4

Answer is  2.4
