Answer:
3/7
Step-by-step explanation:
The first black marble is 10/15 and the second is 9/14. Multiply them together to get 3/7 after you simplify it.
Answer: x = 4.5
Step-by-step explanation:
1) Reorder the terms:
3x = -9 + 5x
2) Solving
3x = -9 + 5x
3) Solving for variable 'x'.
4) Move all terms containing x to the left, all other terms to the right.
5) Add '-5x' to each side of the equation.
3x + -5x = -9 + 5x + -5x
6) Combine like terms: 3x + -5x = -2x
-2x = -9 + 5x + -5x
7) Combine like terms: 5x + -5x = 0
-2x = -9 + 0
-2x = -9
8) Divide each side by '-2'.
x = 4.5
9) Simplifying
x = 4.5
-8a^8b^-2/10a^-4b^-10
= (-8/10) a^(8+4)b^(-2+10)
= -4/5 a^12 b^8
=-4 a^12 b^8 / 5
Answer is A.) -4 a^12 b^8 / 5

Answer:
10+2(50-1)
Step-by-step explanation:
This is an arithmetic sequence
We know the first term a1 = 10
The common difference, d = 2
an = a1+d(n-1)
We want to find the number of terms when n = 50
a50 = 10+2(50-1)
