Step-by-step explanation:
Answer:
h = (2 A)/(b_1 + b_2)
Step-by-step explanation:
Solve for h:
A = 1/2 h (b_1 + b_2)
A = 1/2 h (b_1 + b_2) is equivalent to 1/2 h (b_1 + b_2) = A:
1/2 h (b_1 + b_2) = A
Divide both sides by 1/2 (b_1 + b_2):
Answer: h = (2 A)/(b_1 + b_2)
9,2.5,-4,-10.5,-17
Let's find the difference between two consecutive terms
2.5 - 9 = -6.5
-4 - 2.5 = -6.5
-10.5 - (-4) = -6.5
-17 -(-10.5) = -6.5
We can see that the common difference is -6.5
-6.5 is the common difference between successive terms in the sequence 9,2.5,-4,-10.5,-17
the common difference is negative because we subtract 6.5 to get the next term.
Let the number of apples in a bag be x apples. Basically its assigning a letter (variable) to an unknown quantity.
The phrase in the question can be written as
2x / 19 where x is a variable. 2x means '2 times x'.
