The measures of two base angles of an isosceles trapezoid are 7x – 12 and 5x + 6. What is the measure of x?Select one:
a. 3
b. 5
c. 7
d. 9

Answers

Answer 1

Answer: Because base angles on an isosceles trapezoid are equal you set up this equation
7x - 12 = 5x + 6
-5x+12 -5x +12
2x = 18
/2 /2
x = 9

Division Property of Equality.
Always use opposite operation with side that contains variable.

Isolate variable.
Divide 4 by 4 to get it by itself.

Now do the same to other side.
$12/4=3\nx=3$

12 = 4 x / / / Divide each side by 4. / / / 3 = x .

B.All real numbers
C.All positive numbers
D.All integers

Answers

c(t)

In a function the domain is all the values of t while the range is all the values of c(t).

Since t represents time in minutes, most appropriate domain for c(t) is A. Positive integers only.

Positive integers are numbers that starts with 1 and so on...
