First distribute the 3

12y - 15 = 69

Subtract -15 from both sides

12y = 84

y=7

PROOF:

3 (4 *7 - 5)

3 (28-5)

3 (23) = 69

Y= 7 because if you divide both sides by three you get 3(4y -5) ÷ 3 and 69 ÷ 3 and you simplify it you get 4y - 5 = 23 then add 5 to both sides 4y - 5 + 5 = 23 + 5 simplify that you get 4y = 28 divide again but divide both sides by 4
4y ÷ 4 28 ÷ 4 simplify one more time and y = 7!

Solve for x. (have to add extra letters so the question works)

zloy xaker [14]

Answer:

x=11°

Step-by-step explanation:

-Sum of angles of a triangle should alway be 180 degrees

35+110+2+3x=180

-Add all known values

147+3x=180

-Subtract 147 from both sides

3x=33

-Isolate x by divind both sides by 3

x=11°

Evaluate: 11 + sqrt(-4 + 6×4÷3)

Murrr4er [49]

Answer:

$11+\frac{2\sqrt{15}}{3}$

Step-by-step explanation:

$11 + \sqrt{(-4 + 6\times4\div3)} \\\\11+\sqrt{\frac{-4+6\times \:4}{3}}\\\\\sqrt{\frac{-4+6\times \:4}{3}}=\frac{2\sqrt{5}}{\sqrt{3}}\\\\=11+\frac{2\sqrt{5}}{\sqrt{3}}\\\\\frac{2\sqrt{5}}{\sqrt{3}}=\frac{2\sqrt{15}}{3}\\\\=11+\frac{2\sqrt{15}}{3}$

A biologist is researching the population density of antelopes near a watering hole. The biologist counts 32 antelopes within a

Setler [38]

Answer:

=0.3 per km²

Step-by-step explanation:

Population density is the population per uni area.

Area=πr² Where A is area and r is the radius of the circle.

A=3.14×34

=106.76km²

Population density = Population/Area

=32 antelopes/106.76 km²

=0.3 per km²

The population of antelopes within the given radius is 0.3 per km²
