Hi there! The answer is A) x = 3 or x = 6

Divide by 2.

Factor.

Use the rule AB = 0 gives A = 0 or B = 0

The answer is A) x = 3 or x = 6
Answer:
y = 5
Step-by-step explanation:
22.5(10-y)+27.5y=250

Combind like terms,

Subtract 225 from both equations to isolate the variable.

Divide both sides by 5 to isolate the variable and solve it.

Answer:
121 1/4
Step-by-step explanation:
The stock market went up 30 1/2 points, then down 90 3/4 points. The total change is equal tor 121 1/4.
<u>Given</u>:
The triangle ABC is a right triangle.
The length of AC = 25, the length of AB = 7 and the length of BC = 24
We need to determine the ratios of sin C, cos C and tan C.
<u>Ratio of sin C:</u>
Using the trigonometric ratio, the ratio of sin C is given by

where
and 
Thus, we get;

Substituting the values, we get;

Thus, the ratio of sin C is 
<u>Ratio of cos C:</u>
The ratio of cos C can be determined using the trigonometric ratio.
Thus, we have;

where
and 

Substituting the values, we get;

Thus, the ratio of cos C is 
<u>Ratio of tan C:</u>
The ratio of tan C can be determined using the trigonometric ratio.
Thus, we have;

where
and 
Thus, we have;

Substituting the values, we get;

Thus, the ratio of tan C is
