Answer:

It will take 16 months to grow which is C

Step-by-step explanation:

Answer: 16 months

Step-by-step explanation:

8 / 1/2 = 16

16 x 1/2 = 8

So it would take her 16 months to grow her hair 8 inches.

Solve the equations:
1. 9x - 5 = 5x + 7
2. 8x - 2 = x - 16
3. 8x + 5 = 2x + 23
4. 2x + 8 = 5x + 20
5. 5(2x + 6) = 3x - 5

Answers

Answer:

5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x

step1:- 5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x

step2:- 5x + 3x - 9x - 20 = 8x - 2x + 6 - 5

-x - 20 = 6x + 1

stp 3

-20 = 7x + 1

step 4

-21 = 7x

divide both sides by 7:-

-3 = x

thats the solution x = -3

Answer:

1. X=3, 2. X= -2, 3. X=3, 4. X= -4

Mr. Sonny's science class is calculating the average number of blinks per minute. Jan blinks 126 times in 7 minutes. What is her blinking rate, in blinks per minute?

Answers

18 blinks per min since 126 divided by 7 equals 18

Answer:
b. Every 24 minutes
Step-by-step explanation:
A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.
The first step is to:
Find and list multiples of each time each neon sign blinks.
This means, we find the Multiples of 6 and 8
Multiples of 6:
6, 12, 18, 24, 30, 36
Multiples of 8:
8, 16, 24, 32, 40
The first and common multiple of 6 and 8.
Therefore, the Least common multiple [LCM(6, 8) ] = 24
Hence, they often blink at the same time every 24 minutes.
Therefore, option b.Every 24 minutes is correct.

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.

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

Answers

Ten plus eight teen plus eight

Ten times ten

1/64 is the fraction and the answer

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

What is a fraction?

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:

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

What is the scientific notation of a number?

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
