Dividing means you subtract the exponents. Dividing by a number is the same as changing the sign on the exponent.
x⁰/x² = x⁻² = 1/x²
y⁻³/y⁻¹ = y⁻³⁻⁻¹ = y⁻² = 1/y²
together is 1/x²y², answer B
800+100=900 or 795+115=810 or 800+110=910
The answer is A text me if I’m wrong
Answer:
The answer to your question is: x = 7; y = 6
Step-by-step explanation:
2x+y=20 ( 1 ) Multiply by 5
6x−5y=12 ( 2 )
5 (2x+y=20) = 10x + 5y = 100
10x + 5y = 100
6x − 5y = 12 Eliminate y
16 x = 112
x = 112 / 16
x = 7
2(7) + y = 20 Substitution
14 + y = 20
y = 20 - 14
y = 6
