the equation would be y = 30 + x and if your brother will read for 15 minutes then you'll read for 45 minutes i believe.

Answer: 5</h3>
=================================================
Explanation:
Let's consider the expression (x-y)^2. It expands out to x^2-2xy+y^2. The terms are:
Each of those terms either has a single variable with an exponent of 2, or has the exponents add to 2. Think of 2xy as 2x^1y^1.
In short, this means that the degree of each monomial term is 2.
----------
Now consider (x-y)^3. It expands out into x^3-3x^2y+3xy^2+y^3.
We have terms that either have a single variable and the exponent is 3, or the exponents add to 3. The degree of each term is 3.
----------
This pattern continues.
In general, for (x-y)^n, where n is any positive whole number, the degree of each term in the expansion is n. If you picked any term, added the exponents, then the exponents will add to n.
Answer:
x = 26/15
Step-by-step explanation:
is means equals
52 / x = 30
Multiply each side by x
52 = 30x
Divide each side by 30
52/30 = x
26/15 = x
