Answer:

Step-by-step explanation:

3x + 5y = 15

divide by 15;

3x/15 + 5y/15 = 15/15

x/5 + y/3 = 1

x-intercept= 5

y-intercept= 3

Why do square roots have to be represented as fractional exponents?

shusha [124]

Fractional exponents make square roots easier to simplify. For example, the square root of 1681 isn't obvious. But if you used fractional exponents and prime factorization, you would get 41.

$\sqrt{1681} = 1681^{1/2} = (41^2)^{1/2}= 41^1 = 41$

Vanessa spent 4/5 of her money at the bookstore. In total, the books cost $45. How much did she start with?

Papessa [141]

Answer:

The money she start with is $25.

Step-by-step explanation:

Given:

Vanessa spent 4/5 of her money at the bookstore.

In total, the books cost $45.

Now, to find the money she start with.

Let the money she start with be $x$ .

Money spent at the bookstore $\frac{4}{5} x$ .

Total books cost = $45.

According to question:

$x+\frac{4}{5}x=45$

⇒ $x+\frac{9x}{5} =45$

Adding the variables we get:

⇒ $\frac{9x}{5} =45$

Multiplying both sides by 5 we get:

⇒ $9x=225$

Dividing both sides by 9 we get:

⇒ $x=\$25$

Therefore, the money she start with is $25.
