Answer:

the coefficient of x is 2

Step-by-step explanation:

(3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - (3x - y - z)

Apply the distributive law:  - (a - b)  = -a + b

Therefore, - (3x - y - z) = -3x + y + z

So (3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - 3x + y + z

Collect like terms:                                 = 3x + 2x - 3x - y - y + y + z - z + z

Combine like terms:                              = 2x - y + z

Therefore, the coefficient of x is 2

Therefore, the coefficient of x is 2

Find the annual interest rate. Round your answer to the nearest hundredth of a percent. I=$160.67, P=$2000, t=8 monthsI=$160.67,
Keith_Richards [23]

Answer:

The annual interest rate is 12.05%.

Step-by-step explanation:

The simple interest is given by the formula:

I=\dfrac{P\times R\times T}{100}

Where I denotes interest.

P denotes the principal amount.

R denotes the rate of interest

and T denotes the time period.

I=$160.67, P=$2000, t=8 months=8/12 years (Since 12 months=1 year so 1 month=1/12 year)

160.67=\dfrac{2000\times R \times \dfrac{8}{12}}{100}\\\\R=12.05%

Hence, the annual interest rate is 12.05%.

Use the distributive property to expand 0.05(50 + 40).
AURORKA [14]

Answer:

4.5

Step-by-step explanation:

Here's what I found on google about distributive property:

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Now for the math-

distribute the numbers-  0.05(50)+0.05(40)

solve-  0.05*50= 2.5

0.05*40= 2

2.5+2= 4.5

Hope this helps
