<u>Given</u>:
The given circle with center at C. The lines AB and AD are tangents to the circle C.
The length of AB is (3x + 10)
The length of AD is (7x - 6)
We need to determine the value of x.
<u>Value of x:</u>
Since, we know the property of tangent that, "if two tangents from the same exterior point are tangent to a circle, then they are congruent".
We shall determine the value of x using the above property.
Thus, we have;
AB = AD
Substituting the values, we get;

Subtracting both sides of the equation by 7x, we get;

Subtracting both sides of the equation by 10, we get;

Dividing both sides of the equation by -4, we get;

Thus, the value of x is 4.
Answer:
Assuming that Janet spent an equal amount of time on each question, he would have spent 75 seconds on each question.
Step-by-step explanation:
10 minutes = 600 seconds
600 seconds / 8 questions = 75 seconds.
Answer:
64 = 4x + 7 Each bag of rice weighs 14.25 pounds.
Step-by-step explanation:
Each package is 64 pounds, which give us one side of the equal sign. The other side is ehre we make the 64 pounds. There is one 7 pound bag of beans, and four equal bags of rice. To find the pounds per bag of rice, we do 64-7 to get 57, then 57/4 to get 14.25
