The sum of two numbers is 30. If three times the smaller number is equal to two times the bigger one, find the numbers.

MAVERICK [17]

Let the smaller number be x and the bigger number be y.
Therefore, 3x = 2y $= > x = \frac{2y}{3}$ $x + y = 30 \\ = > \frac{2y}{3} + y = 30 \\ = > \frac{2y + 3y}{3} = 30 \\ = > \frac{5y}{3} = 30 \\ = > y = \frac{30 \times 3}{5} \\ = > y = 18$
Therefore, the smaller number = 30 - 18 = 12

To which subsets of real numbers does the following number belong? square root of 30

LenaWriter [7]

In order to determine which subset it belongs, we must rewrite

$\sqrt(30)$

$\sqrt(30)=\sqrt(2\times \times 3 \times 5)$

$\Rightarrow \sqrt(30)=\sqrt(2 \times 3\times 5)$

$\Rightarrow \sqrt(30)=\sqrt(2) \times \sqrt(3) \times \sqrt(5)$

All these three numbers are irrational numbers, hence their product is also irrational

<h2> $\Rightarrow \sqrt(30)$ </h2><h2>belongs to the set of irrational numbers</h2>

The slope of a line is -1/4 and the y-intercept is 8. Whats the x-intercept?

Fed [463]

Slope = -1/4
y-interept = 8
⇒equation: y = -1/4x + 8

x-intercept ⇒ when y = 0
0 = -1/4x + 8
1/4x = 8
x = 8 x 4
x = 32

Answer: x-intercept = (32,0)
