Solve AND graph the inequality below. −2x−4≤11

ankoles [38]

Answer:

$x\ge \:-\frac{15}{2}$

The graph of the inequality is attached below.

Step-by-step explanation:

Given the inequality

$-2x-4\le 11$

$\mathrm{Add\:}4\mathrm{\:to\:both\:sides}$

$-2x-4+4\le \:11+4$

$-2x\le \:15$

$\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}$

$\left(-2x\right)\left(-1\right)\ge \:15\left(-1\right)$

$2x\ge \:-15$

$\mathrm{Divide\:both\:sides\:by\:}2$

$\frac{2x}{2}\ge \frac{-15}{2}$

$x\ge \:-\frac{15}{2}$

The graph of the inequality is attached below.

At a football stadium, 25% of the fans in attendance were teenagers. If there were 130 teenagers at the football stadium, what w

Trava [24]

Answer:

Total number of people in the stadium = 520

Step-by-step explanation:

Let the total number of people in the stadium = x

Since, 25% of the fans are teenagers, number of teenagers in the stadium

= 25% of x

= $\frac{25}{100}\times x$

= 0,25x

If the number of teenagers in the stadium = 130

0.25x = 130

x = $\frac{130}{0.25}$

x = 520

Therefore, total number of fans in the stadium = 520.
