answer:
22 weeks
step-by-step explanation:
- set up a proportion
- use x for how long it would take her
- cross multiply to solve
39 / 2 = 429 / x
429 (2) = 39x
858 = 39x
x = 22
- it would take her 22 weeks
- you can change the units by conversion based on what is asked
Answer: D
Step-by-step explanation:
From the equation given , ( -3)⁰(2x⁻¹y⁻¹)²
Recall :From the laws of indicies,
x⁰ = 1 ,and (xᵃ)ᵇ = xᵃ ˣ ᵇ = xᵃᵇ. and x⁻¹ = 1/ₓ
Therefore,
(-3)⁰ = 1,
( 2x⁻¹y⁻1 )² = 2²x⁻¹ ˣ ²y⁻¹ x ²
= 2²x⁻²y⁻²
=4x⁻²y⁻²
Now going by the law above, the expression will be
=4/ₓ²y²
So the answer is D
