A = 16/3, b = 28/3

Answer:

a = 5 1/3

Step-by-step explanation:

a+b+b = 24

a + 2b = 24

b-a =4

a = b - 4

b - 4 + 2b = 24

3b = 24 + 4

b =28/3

substitute this in a = b - 4

a = 28/3 - 4

a = 28/3 - 12/3

a = 16/3

a = 5 1/3

Find 3 fractions that are equivalent to 3/8. explain your method
Nikolay [14]
Hey Aarya!

If we `scale` both the numerator and denominator by the same value, then we can create other equivalent fractions. By scale I mean: Multiply both the top and bottom of the fraction by the same value.

So here is one we can try.
Let's multiply numerator and denominator by 3.
\rm \frac38\cdot\frac33=\frac9{24}
Yay we did it! We found another fraction which is equivalent to 3/8.

What is the domain of x^3 -2 +1
Furkat [3]

Answer:

All real numbers

Step-by-step explanation:

Assuming the polynomial is

{x}^{3}  - 2x + 1

Then the domain is all real numbers.

The domain are all values of x, for which the given function is defined.

The reason is that, polynomials are defined everywhere on the real number line.

We can write this as {x|x is all real numbers} .

Or (-∞,+∞)
