Answer: x = 13
Step-by-step explanation:
8x + 2 = 14x - 76
78 = 6x
x = 13
13x = 39 can replace 3x + 5y = 59 in the original system and still produce the same solution.
Answer:
10°C
Step-by-step explanation:
(50°F − 32) × 5/9 = 10°C
A complement adds up to 90 degrees, so we just need to halve that, to get 45 degrees.
Answer:
A
Step-by-step explanation:
The n th term ( explicit formula) for a geometric sequence is
f(n) = a
where a is the first term and r the common ratio
Here a = 2 and r = - 8 ÷ 2 = - 4, thus
f(n) = 2
