answer is b juicy how to do it

Answer:

2x + 2

Step-by-step explanation:

Simply distribute 2 to each of the terms (you multiply)

2(x + 1)

2x + 2

[tex]\huge\boxed{Hi!}[/tex]

The Distributive Property  states that

a(b+c)=ab+ac

Let's use this to solve our math problem:

2(x+1)=2x+2

This is our final answer.

You need to times 2/3 twice

-2/-3 * -2/3

Answer:

½, √0.28, 0.58

Step-by-step explanation:

you need to first change everything into decimals so, ½ = 0.5 , √ 0.28 = 0.53 and 0.58 remains the same. Now you can arrange them from least to greatest once they are in a common form.

First, let's let's evaluate the numerator and denominator separately.

The numerator: (-2)^2(3)(4) - (-1) = 48 + 1 = 49

The denominator: (-2)^2 = 4

Now that the numerator and denominator are simplified, let's take the square root of 49/4

sqrt(49/4) = 3.5

Answer:

0.143

Step-by-step explanation:

1) convert to decimal form: 0.142857

2) rounding to nearest thousandth (3rd decimal place)

3) number is higher than 5 so it rounds up to 0.143

Answer:

Step-by-step explanation:

Answer:

40.38912735 or about 40 miles per hour (rounded to the nearest whole number)

Step-by-step explanation:

1.) You want to convert kilometers per hour to miles per hour.

2.) There are 0.62137119 miles in 1 kilometer.

3.) Multiply 65 by 0.62137119

4.) That equals 40.38912735

5.) This answer can be rounded to 40 mph.

Answer:

Answer:

the cost of the three new CDs is $44.28

Step-by-step explanation:

Here in this question, we are interested in calculating the cost of 3 new CDs cost.

From the question, we already know the cost of one. The cost of three would be 3 multiplied by the cost of one.

The cost of the three excluding the sales tax = $13.79 * 3 = $41.37

The sales tax for the three pieces = 3 * $0.97 = $2.91

The cost of the three CDs including the sales tax = $41.37 + $2.91 = $44.28

Answer:

Step-by-step explanation:

9. (-2, 2) (4, 3)

  (3 - 2)/(4 + 2) = 1/6

10. (-2, 2) (3, 4)

     (4 - 2)/(3 + 2) = 2/5

11. (3 - 13)/(0 + 16)= -10/16= -5/8

12. (-19 - 0)/(7 + 12) = -19/19= -1

The expression for temperature change in City A is 9 + (-8)

The amount the temperature changes for City A = 1°F

The expression for temperature change in City B is -1 + (-3) = -4°F

The amount the temperature changes for City B = -4°F

Based on the available data:

The expression for that represents the temperature change from 8 am to 10 am is, therefore;

The temperature change from 8 am to 10 am are

Sum, change from 8 am to 10 am = 9 + (-8) = 1°F

The temperature change from 8 am to 10 am are

Sum, change from 8 am to 10 am = -1 + (-3) = -4°F

9^c = 243

3^(c)*2 = 243

3^(c)*2 = 3^5

Since the bases are the same the powers can be equated.

2*c =5

c = 5/2

c = 2 1/2

Check

9^2.5 = 243
