We are asked for the number of <span>six-digit odd numbers that can be formed. the left-most digit should not be zero because it make the number -five digit already. An odd number ends only in 1, 3, 5, 7 and 9. Using counting, the 6th digit can only have 5 numbers, the 5th, 4th, 3rd, and 2nd can have, 10 numbers. The first number can only have 9 numbers. Hence the total number is 450,000</span>
1. 3x + 5x + 14x = 22x
2. 4x + 7 + 11x = 15x+7
3. 10x + 8 - 3x= 7x+8
4. 6x - 5 + X - 11 = 7x-16
5. -8x + 19 + 2 - 2x = -10x+21
6. X + 23 + 4x - 34 - X = 4x-11
7. 105 + 27x - 68 - 19x - 27 + x = 9x +10
8. 7x + 16 - 3x + 3 - 2x - 2x = 19
9. -18 + 6 - 4x + 10 - 11x + 2 = -15x
10. 16 + 4x - 12x - 28 - 6x + 17 + x - 1 = -13x+4
= [3x3^-2x(-2)^6/2x3^-1x(-2)^5]^2 = 1
Answer:
the answer is independent
Explanation:
Since we have given that
Speed at which Eugene walked all the way to school = 3 mph
After realizing that she forgot her math book, she ran back
Speed at which Eugene walked back to her house = 7 mph
Let the distance between her house and her school be x
According to question,
Hence,
