14x + 6 = 5x - 3 with solution

Schach [20]

hey there

the answer is

14x + 6 = 5x + -3

6 + 14x = 5x + -5

6 + 14x = -3 + 5x

6 + 14x + -5x = -3 + 5x + -5x

Combine like terms: 14x + -5x = 9x

6 + 9x = -3 + 5x + -5x

Combine like terms: 5x + -5x = 0

6 + 9x = -3 + 0

6 + 9x = -3

6 + -6 + 9x = -3 + -6

Combine like terms: 6 + -6 = 0

0 + 9x = -3 + -6

9x = -3 + -6

Combine like terms: -3 + -6 = -9

9x = -9

Divide each side by '9'.

x = -1

Simplifying

x = -1

thank you

A tree grows 20 percent taller every year after it is planted. The tree was 12 feet tall when planted. How tall will it be after

Lelu [443]

Answer:

Option A; 74.3 feet

Step-by-step explanation:

~ Here we can see that this problem is set to be so that compound interest is applied ~

1. If compound interest is to be applied, it would be that the "20 percent" is the interest, the principle number ( start value ) ⇒ 12 feet in height, and the time is 10 years.

2. Let us approach this problem step by step. Instead of substiting values into a compound interest formula, let us simply attempt a variation of that process...

3. 20 percent is, in a decimal form, ⇒ 0.2

4. Now add 1 to this value 0.2, to get ⇒ 1.2

5. If we were to consider the formula, 1.2 would first be exponentially multiplied by itself 10 time, considering that it is to the power of 10 years. In other words ⇒ 1.2^10 = 6.191736422..........

6. Now let us multiply this infinite value 6.19...... by the principle quantity 12 feet ⇒ 6.191736422.......... * 12 = <em>(About) 74.30083707.......</em>

7. If we were to round this value, it would be to ⇒ 74.3 feet, or in other words the first option; <em>Option A</em>
