I NEED HELP NOW FOR A 7TH GRADE MATH PROB

Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.

Step-by-step explanation:

Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.

Therefore, Mathematics is the abstract study of topics such as quantity (numbers), structure, space, and change!

Answer:

x + 14 = 5x - 74

x - 5x = -4x

-74 - 14 = -88

-4x = -88

-4x/4 = -88/-4

x = 22

Answer:

6/7 simplest form is 6/7

2/2 simplest form is 1/1

Tell me if wrong!

Step-by-step explanation:

This is one slight annoyance when it comes to sig figs, in my opinion anyway. You did the steps correct. The 639 bumps up to 640, so 6396 rounds to 6400 when rounding to 3 sig figs.

Normally the trailing zeros, ie zeros on the right, are not significant. So 6400 shows only 2 sig figs. What we need to do is draw a horizontal line over the first zero to show that it is significant (while the other zero is not significant)

So you'll write it like this [tex]64\overline{0}0[/tex]

This notation can be problematic when it comes to decimals because it could be easily mixed up with the repeating decimal notation.

When you convert [tex]64\overline{0}0[/tex] to scientific notation, you would get [tex]6.40 \times 10^3[/tex].

In short: [tex]64\overline{0}0 = 6.40 \times 10^3[/tex]

Here the zero is significant because the zero is present in the scientific notation result. Writing [tex]6.4 \times 10^3[/tex] shows 2 sig figs while [tex]6.40 \times 10^3[/tex] has 3 sig figs.

It's similar to how the number [tex]5.7[/tex] has 2 sig figs while [tex]5.70[/tex] has 3 sig figs. While the zero is trailing, having it after a decimal point indicates to the reader that you achieved this level of accuracy.

Answer:

1. 1 cup of concentrate would use 7.5 cups of water.

2. 10 cups of concentrate would use 75 cups of water.

Step-by-step explanation:

Because 1/3 cup of concentrate is mixed with 2 1/2 cups of water, to find how much water one cup of concentrate would use, you would have to multiply both 1/3 and 2 1/2 (2.5) by 3. Then, you get 1 cup of concentrate equals 7 1/2 (7.5).

To find the answer to the next question, simply multiply by 10.

Answer:

14 socks.

Step-by-step explanation:

3 1/2 / 1/4

= 7/2 / 1/4

= 7/2 * 4

= 28/2

= 14 socks.

Answer:

14

Step-by-step explanation:

Mrs. taylor can knit 4 socks in an hour, so if she has to go to her meeting in 3 1/2 hours, she should be able to knit 14 pairs of socks. The reason for this is in 3 hours she can knit 12 socks because 4 times 3 is 12. Then, in half an hour she can knit 2 socks because she can knit one pair in 1/4 so in 1/2 it would be 2.

Answer:

x=2

Step-by-step explanation:

x+(-4) is the same as x-4

First you have to get X alone so you add 4 to both sides because when you add 4 to both sides it will take away the 4 on the x side.

x-4=-2

+4    +4

x= -2+4                or you can see this as 4-2 which is 2

x=2

Answer:

Shorter than 15IN, 5.9 or 6 inches

Hope this helps:)

Step-by-step explanation:

The ribbon is shorter than 15 inches, and its length is approximately 5.91 inches.

Given that a ribbon has a length of 15 cm, we need to calculate the length in inches,

To determine the length of the ribbon in inches, we need to convert the length from centimeters to inches.

To convert centimeters to inches, we can use the conversion factor 1 inch = 2.54 centimeters.

The length of the ribbon is 15 centimeters. To convert this to inches, we divide 15 by 2.54:

15 cm / 2.54 cm/inch = 5.91 inches (rounded to two decimal places).

So, the ribbon is shorter than 15 inches.

The ribbon is approximately 5.91 inches long.
