Answer:
x = 5
Step-by-step explanation:
Given equation as:
= 1
now,
writing each side as power of 2
2⁰ = 1
therefore,
= 2⁰
also, we know the property that , when the number having the same bases gets divided , the powers of the number gets subtracted
therefore,
= 2⁰
now for the equality the power of 2 both sides should be equal
thus,
⇒ 2x-(x+5) = 0
or
⇒ 2x = x + 5
or
⇒ 2x - x = 5
or
⇒ x = 5

With 10 to the power to a negative number, it's easier.
Here's a trick: The negative number is the places to the right of the decimal. The last number is a 1, while the rest are 0s.
From this, we get:
Answer:
1. a. His new texting speed after one month is 2 + 1/2 = 2.5 characters per second.
b. After two months it will be 2 + (1/2) * 2 = 3 characters / second.
c. Answer is 2 + 1/2 * 3 = 3.5 characters/second/.
2. The answer is s = 1/2m + 2
3. To solve for m we write 8 = 1/2m + 2 → 6 = 1/2m → m = 12 months.
4. 10r + 4 = 8 → 10r = 4 → r = 0.4
5. The variable r represents the rate she must increase her texting speed by per month.
6. A scenario could be "Allison has 37 marbles in a jar. She took out 5 from the jar and wants to divide the remaining amount equally among her 8 friends. How many marbles does each friend get?".
