This is the answer of this question
Answer: -2.5
Step-by-step explanation:
The average can be found by adding up the numbers then dividing by how many numbers there are in this case there are two numbers.
-30+25=-5
-5/2 = -2.5
(6 × 10⁷)/(5 × 10⁴)
We could simplify the exponential number of 10 by substracting the exponent number, it could be written as
= 6/5 × 10⁷⁻⁴
= 6/5 × 10³
= 1.2 × 10³
(This is the final answer)
Step-by-step explanation:
x = number of novels
y = number of dictionaries
x = 8y
88x + 208y = 13680
now, using the identity of the first equation in the second equation gives us
88(8y) + 208y = 13680
704y + 208y = 13680
912y = 13680
y = 13680/912 = 15
x = 8y = 8×15 = 120
so, there were 120 novels and 15 dictionaries sold.
Answer:
