Answer:
28< 6
Step-by-step explanation:
34 < 6 + d
Subtract 6 from each side
34-6 < 6 + d-6
28< 6
Answer: 3 (first choice)
A power to a power gives a multiplication of powers, e.g.,
(7¹⁰)² = 7²⁰
So the left side is 7²⁰ / 7⁴ and we divide the top and bottom by 7 get we
(7¹⁰)² / 7⁴ = 7²⁰ / 7⁴ = 7¹⁹ / 7³
We compare that to the right side 7¹⁹ / 7ˣ and it's clear x=3.
Answer: -6 = x
Step-by-step explanation: Start by distributing through the parentheses
on each side of the equation to get 5x - 40 = 7x - 28.
Now move your x's to the right and
numbers to the right and you get -12 = 2x.
Divide both sides by 2 and -6 = x
