To figure this out simply divide 22 by 2, 11, so therefore 11+11=22. subtract 3 from 11, add 3 to the other 11 because 3+3=6, making the correct answer 8+14=22.

You could also set up the equation

x + x - 6 = 22
2x -6 = 22
2x = 28
x = 14

Since x is 14 then the other number is 14 - 6 = 8

The numbers are 14 and 8

Garrett chooses to invest $1800 in a simple. The account earns 3% interest over 5 years which equation represents garrets invest

Alla [95]

The interest earned in 5 years would be $270

<u>Explanation:</u>

Given:

Principal, P = $1800

Rate of interest, r = 3%

Time, t = 5 years

Simple interest, I = ?

We know,

$I = \frac{p X r X t}{100}$

On substituting the value we get

$I = \frac{1800 X 3 X 5}{100} \\\\I = 270$

Therefore, interest earned in 5 years would be $270

The table below shows the price in dollars for the number of roses indicated is the price proportional to the number of roses ex

makvit [3.9K]

Answer:

Price of roses is proportional to the number of roses.

Step-by-step explanation:

Let the price of roses are proportional to the number of roses.

Equation representing this phenomenon will be,

P = k(R) ⇒ k = $\frac{P}{R}$

where 'P' = price of the roses

R = Number of roses

k = Proportionality constant

If we substitute the values of P and R and we get the same value of constant 'k', then the equation will be true.

For R = 3 and P = $9

k = $\frac{9}{3}$

k = 3

For R = 6 and R = 18

k = $\frac{18}{6}$

k = 3

K is same in both the conditions, therefore, Price of roses are proportional to the number of roses.

I need help remembering the steps to solve a polynomial equation

murzikaleks [220]

Example 1 – Solve: 3x3 = 12x

Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.

3x^3-12=0

Step 2: Use a factoring strategies to factor the problem.

3x(x^2-4)=0
3x(x+2)(x-2)=0

Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.

3x=0 or x+2=0 or x-2=0

Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.

x=0 or x=-2 or x=

I hope this helped you!
