Step-by-step explanation:

y - x = 3x +2

y=3x+x+2

y=4x+2.......(1)

2x + 2y = 14 - y

2x+2y+y=14

2x+3y=14.........(1)

substituting value of y in equation 1

2x+3(4x+2)=14

2x+12x+6=14.

14x=14-6

14x=8

x=8/14=4/7

substituting value of x in equation 1

y=4×4/7+2=30/7

x=4/7

y=30/7

205 students enrolled in a freshman-level chemistry class. By the end of the semester, 4 times the number of students passed as
AlexFokin [52]

Answer: 164 students passed and 41 students failed.

Step-by-step explanation:

Let the number of students be x

x students failed, but 4 times the failed students passed.

So 4x students passed and x students failed.

4x + x = 205

5x = 205

x = 205/5

x = 41

41 times 4 is 164 and 41 times 1 is 41.

So 164 students passed and 41 students failed

A windstorm Knocks a pole over, forming a slight angle with the ground. The pool is 18 m tall, and the top of the pool is now 15
ivolga24 [154]

Answer:

Step-by-step explanation:

Looking at the scenario, a right angle triangle is formed.

The length of the pole represents the hypotenuse of the right angle triangle.

The distance from the top of the pole to the ground represents the opposite side of the right angle triangle.

To determine the angle formed by the pole and the ground, we would apply we would apply the Sine trigonometric ratio.

Sin θ = opposite side/hypotenuse. Therefore,

Sin θ = 15/18 = 0.833

θ = Sin^-1(0.833)

θ = 56.4°
