There are a total of 375 flamingos, parrots, herons, and chachalacas at the Famous Bird Sanctuary. The ratio of flamingos to par

Tems11 [23]

Answer:

Step-by-step explanation:

Since the ratio between flamingos and chachalacas is 2:1, we see that the ratio of flamingos to chachalacas to parrots to herons is 10:5:7:3. The sum of these numbers is 25, so every 'ratio number' gets 375/25 = 15 animals. So the number of chachalacas is 15 * 5 = 75.

Which number line represents the solution set for the inequality –4(x 3) ≤ –2 – 2x?

Anna71 [15]

The solution to the inequality expression is x ≥ - 5

<h3>Inequality expressions</h3>

Inequality are expressions not separated by an equal sign. Given the inequality;

–4(x + 3) ≤ –2 – 2x

Expand

-4x - 12 ≤ -2 - 2x

Collect the like terms

-4x + 2x ≤ -2 + 12

-2x ≤ 10

Divide both sides by -2

-2x/-2 ≤ 10/-2
x ≥ - 5

Hence the solution to the inequality expression is x ≥ - 5
