Area = 1/2 * base * height
6 = 1/2 * base * 3
lengths of the base = 6 / (3*1/2) = 6 / 1.5 = 4 inches answer
Answer:
Step-by-step explanation:
The equation
2 = (1/6)x represents this situation.
2 is 1/6 of some value. In this case, the value is the total number of marbles. 2 represents 1/6 of the total number of marbles is how to read that equation in context. Solve that equation for x
2 = (1/6)x
12 = x (multiply both sides by 6 to get rid of the fraction)
You have to jusitfy the step that leads from sin (x) = a/c and cos(x) = b/c to sin^2 (x) + cos^2(x) = [a^2 / c^2] + [b^2 / c^2].
As you can see go from the first statement to the second by substituting the value of sin(x) by a/x and the value of cos(x) by b/c.
Then, the answer is the option b. substitution property of equality.
