Answer:
x = 3
Step-by-step explanation:
-6x - 20 = -2x + 4 (1 - 3x)
Distributive property
-6x - 20 = -2x + 4 - 12x
Combine like terms
-6x - 20 = -14x + 4
Add 14x to both sides
-6x - 20 + 14x = -14x + 4 + 14x
Simplifying
8x - 20 = 4
Add 20 to both sides
8x = 24
Divide both sides by 8
x = 3
The Awnser would be 20.6 rounded up to 21. The final Awnser is 21
The matching is given below.
- Doubling ⇒ 2
- Quadrupling ⇒ 4
- Tripling ⇒ 3
- Halving ⇒ 1/2
<h3>What is an exponent?</h3>
Let a be the initial value and x be the power of the exponent function and b be the increasing factor. The exponent is given as
y = a(b)ˣ
You are asked to write exponential equations from word problems.
We know that factor 2 represents doubling, factor 4 represents quadrupling, factor 3 represents tripling, and factor 1/2 represents halving.
Then the matching is given below.
- Doubling ⇒ 2
- Quadrupling ⇒ 4
- Tripling ⇒ 3
- Halving ⇒ 1/2
