Answer:
Concept: Mathematical Sequences
- Let An be 99 a double digit multiple
- The sequence is finite.
- Finite= restricted and not bounded to positive infinity
- By that logic the last possible digit is 999999999999999999999999999999999999999999999
Here are the steps
(4*3)+(4*-2x)=(4x)+(4*-6)
...12+-8x=16x-24x
...-8x+24x-16x=-12
0x=-12
x=-12/0
dividing by 0.
so there is no solution.
Answer:
I believe its 45 degrees.
Answer:
Correct option: first one -> 40
Step-by-step explanation:
To solve this problem, we can use a compound rule of three.
The quantity of chocolate and the weight of each chocolate are inversely proportional: to achieve the same earning, if we have more chocolate, we need less grams per chocolate.
Then, the rate of change in quantity multiplied by the rate of change in the grams will be equal to the rate of change in the final earning.
So we have that:
(3/20) * (14/X) = 21/400
42 / 20X = 21 / 400
1 / 10X = 1 / 400
10X = 400
X = 40 grams
Correct option: first one
