What is the value of 3 minus (negative 2)?

A number line going from negative 5 to positive 5.
–5
–1
1
5

Answer:

i am kind of confused by the question but i would say to but all the numbers below 1 in the 10^-4 section and the numbers above 1 in the 10^6.

i might be wrong i don't what the question is really.

Step-by-step explanation:

Alan is converting large and small numbers from standard notation to scientific notation

10⁶  = 4.03 x 10⁶, 2.93 x  10⁶, 5 x  10⁶

10⁻⁴ = 1.2x 10⁻⁴, 6 x 10⁻⁴,  5.9 x 10⁻⁴

The standard form for a number is a method by which we write number in a format like b×10ˣ. The value of b should be in between 0 to 10.

Given that,

The numbers,

0.00012, 4030000, 2930000, 0.0006, 5000000, 0.00059

Taking number, 0.00012

To convert it into scientific notation,

It should be in from of  b×10ˣ,

So, now dividing and multiplying 10000 into the number 0.00012,

⇒  0.00012 x (10000/10000)

⇒  (0.00012 x 10000)/10000

⇒   1.2/10000

⇒   1.2x 10⁻⁴

Similarly,

0.0006 can be written as 6 x 10⁻⁴

And  0.00059 can be written as 5.9 x 10⁻⁴

Now taking number, 4030000

To convert it into scientific notation,

It should be in from of  b×10ˣ,

So, now dividing and multiplying 1000000 into the number 4030000,

⇒ 4030000 x (1000000/1000000)

⇒  (4030000 / 1000000) x 1000000

⇒   4.03  x 1000000

⇒   4.03 x 10⁶

Similarly,

2930000 can be written as 2.93 x  10⁶

And 5000000 can be written as 5 x  10⁶

Step-by-step explanation:

Figure the rest out

Answer:

y = - 4x + 20 ... slope=-4   y intercept:20

Step-by-step explanation:

2y+8x=20

2y=-8x+20

y = - 4x + 20 ... slope=-4   y intercept:20

(y = mx + b)

Answer:

The constant of proportionality is the ratio between two directly proportional quantities. In our tomato example, that ratio is $3.00/2, which equals $1.50. Two quantities are directly proportional when they increase and decrease at the same rate.

Answer: 6(4/x)

Step-by-step explanation:

Quotient means division so it is 4 divided by a number. This number is unknown so it’s a variable making it 4/x

You also need to multiply this by 6 so 6(4/x)

Answer:C. 32

Step-by-step explanation:

Answer:

Length = 11 1/3 ft; Width = 4 2/3 ft

Step-by-step explanation:

First question:

The length is 2 more than twice the width, so

L = 2W + 2

Second question:

2L + 2W = 32

L = 2W + 2

Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.

2L + 2W = 32

2(2W + 2) + 2W = 32

4W + 4 + 2W = 32

6W = 28

W = 28/6 = 14/3 = 4 2/3

L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3

L = 11 1/3

W = 4 2/3

Answer: Length = 11 1/3 ft; Width = 4 2/3 ft

The required probability of not stamp not along an outer edge is 8/25.

A fraction is a numeral that represents a rational number.

Let a and b be two numbers, then their fraction can be represented as a/b.

Given that,

Total numbers of stamp in a stamp sheet of 10 by 10 = 100,

On one edge there would be 10 stamps but on each diagonal there will be 1 stamp common,

Therefore, total number of stamps  on outer edge will be = 9 x 4 = 36

Remaining stamps = 100 - 36 = 64

The fraction value of 64 out of 100 = 64 / 100 = 8 / 25

The required fraction value of stamps is 8 / 25.

Answer: 9 essay questions

Step-by-step explanation:

The test has 26 questions

The test is worth 123 points

The test has two types of questions:

Multiple choice worth 3 points each

Essays worth 8 points each

Let the number of multiple choice questions be, m, and the number of essay questions be , e.

This forms a simultaneous equation below:

m + e = 26 ... (i)

3m + 8e = 123 ... (ii)

Multiplying (i) by 3 and (ii) by 1 we get:

3m + 3e = 78 ... (i)

3m + 8e = 123 ... (ii)

Subtracting (ii) - (i) we get;

0m + 5e = 45

5e = 45

e = 45 ÷ 5 = 9

So there are 9 essay questions.

and;

m + 9 = 26

m = 26 - 9 = 17

There are also 17 multiple choice questions.

Answer:

Variables: you are correct

Coefficients: -2

Constant: 3/7

Step-by-step explanation:

Variables are letters used in math so you were correct.

Coefficients are numbers with a variable. So to find the coefficient you would look for a number "connected" to a variable. This would be -2 because it is being subtracted from the first term.

The constant is 3/7 because you could put it on a number line.
