Step-by-step explanation:

2/3 (12x+30)-12=4/10 (15x+10)

30×2/3 (12x+30)-12×30=4/10 (15x+10)×30

10(12x+30)-360 =12 (15x+10)

120x+300-360=180x+120

300-360-120=180x-120x

-180=60x

-180/60=60x/60

-30=x

A ladder leans against a building, forming an angle of 60° with the ground. The base of the ladder is 6 feet from the building.
ollegr [7]

Answer:

12 ft

Step-by-step explanation:

There are 2 known angles in the right triangle (90: because the building is perpendicular to the ground, and 60) which means the third angle is 30.

The side of the triangle that is across from the 30 degree angle is HALF the one across from the 90 degree angle. Which means the lengthy is 6*2 and that equals 12.

David's bowling score is 6 less than 3 times Aaron's score. The sum of their scores is 214. Find the score of each student. Use
Alex

Step-by-step explanation:

Let aron's variable be = a

Let davids variable be( 6 less tan 3 times aron) = 3×a-6

Thier sum is =214

So,

3×a-6 + a = 214

3a -6 +a = 214

(transpose)

3a + a = 214 + 6

4a = 220

a = 220/4

a= 55

Thus,aron's score is = 55

And davids score is (3×a-6) = 3×55-6 = 159

Checking,

Aron score + david score = 214

55 + 159 = 214

SO, ITS CORRECT

HOPE IT HELPS :)

Describe how an ordered pair represents a point on a coordinate plane. Include the terms x-coordinate, y-coordinate, and origin
Blababa [14]
When we look at an ordered pair, it will be presented as (x,y)

The first term, x  (called the x-coordinate), will tell us how far we should count outwards from 0 (The Origin). The second term, y (called the y-coordinate), will tell us how far we will count outwards from our x coordinate.

I hope this helps! If you would like me to elaborate more just let me know:)
