Answer:
96
Step-by-step explanation:
commom difference = d
a₆ + a₇ = 16
a₅ + a₈ = (a₆ - d) + (a₇ + d) = a₆ + a₇ = 16
a₄ + a₉ = (a₆ - 2d) + (a₇ + 2d) = a₆ + a₇ = 16
Similarly,
a₃ + a₁₀ = 16, a₂ + a₁₁ = 16, a₁ + a₁₂ = 16
so
a₁ + a₂ + ... + a₁₁ + a₁₂ = 6 x 16 = 96
Answer: true
Step-by-step explanation:
The given expression is equivalent to the expression - 11/6 n - 1/12. Then the correct option is C.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The sum of capacity minus three and one-third times n plus one-sixth ended capacity + capacity one and three-sixths times n minus three-twelfths end quantity.
Let n be the number. Then the expression will be
⇒ -(3 1/3)n + 1/6 + (1 3/6)n - 3/12
Simplify the equation, then we have
⇒ -(3 1/3)n + 1/6 + (1 3/6)n - 3/12
⇒ -10/3 n + 3/2 n + 1/6 - 1/4
⇒ -11/6 n - 1/12
The given expression is equivalent to the expression - 11/6 n - 1/12. Then the correct option is C.
