Answer:
6
Step-by-step explanation:
they both would be equal to each other.
5x-7 = 23
5x = 30. (add 7 to both sides)

Solution:
we are given that
Dan borrowed $750.00(=P) from his brother who is charging him 8% (=r)simple interest.
Dan pays his brother back in 6 months(=t).
we have been asked to find- how much does he have to pay back including the interest?
As we know that

Substitute the values we get

Hence net payable amount is 750+30=$780
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
