Answers

Answer 1
Answer: you can multiply the fraction by any number you want so the new fraction gonna be equivalent to your fraction like : (4 × 2)/(5 × 2) = 8/10 or  (4 × 3) / ( 5×3) = 12/15 so 4/5 = 8/10 = 12/15 :))
i hope this be helpful 
have a nice day

Answers

Steps:
1. 6x=4y + 7
2. You have to write it in slope intercept to get the slope and y-intercept.
3. Subtract 7 on both sides
4y= 6x-7
4. Divide everything by 4
5. Y= 3/2x + -7/4
6. Slope= 3/2 y-intercept= -7/4

What times what equals 63

Answers

The question is asking to state the two number that when multiplied the product would be 63, base on my calculation, I would say that the answer would be 7 * 9 and 3 * 21. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications 

One of such combinations is 9 x 7 = 63.

Here we have to find two numbers,

Such that,

Their product is 63.

Since we know that,

Using operations like addition, subtraction, multiplication, and division, a mathematical expression is defined as a group of numerical variables and functions.

There are following such numbers are,

63 x 1 = 63

21 x 3 = 63

9 x 7 = 63

A student skipped a step when she tried to convert 18 hours into seconds,and she got the following incorrect result:
18 hours
60 seconds)
= 1080 seconds
1 minute
What conversion ratio did she skip in this multiple-step conversion?

Answers

Answer:

The conversion of minutes to seconds is skipped in multiple-step conversion.

Step-by-step explanation:

Given:

To convert 18 hours into seconds.

Now, to get the conversion ratio skip in this multiple-step conversion.

First we need to convert hours into minutes:

1 hour = 60 minutes.

So, 18 hours = 18* 60 minutes

                     = 1080 minutes.

Then, we convert minutes into seconds:

1 minute = 60 seconds.

So, 1080 minutes = 1080* 60 seconds

                             =  64800 seconds.

Thus, 18 hours =  64800 seconds.

As given in question the conversion from hours to seconds is there but the conversion of minutes to second is not there it is skipped so the result is incorrect.

Therefore, the conversion of minutes to seconds is skipped in multiple-step conversion.

Solve for x

8x-15=17

Answers

8x-15=17 now to get rid of the 15 simply add 15 to each sides like so

8x-15=17
    +15|+15
      0  | 32
then bring down 8x and 32, then you have to divide 8 on both sides to get rid of 8 and have x and divide 8 and 32 and then you get x 

(8x)/(-8) |  (32)/(8)
                                   
   x = 4

Multiply 4 and 7. Then, divide by q.

Answers

Answer:

28/q

Step-by-step explanation:

4 times 7 equals 28 and then divide 28 by q

Final answer:

Multiply 4 and 7 to get 28. Then, divide the result, 28, by q to get your final answer of 28/q.

Explanation:

To multiply 4 and 7, you simply multiply the two numbers together: 4 * 7 = 28. To then divide by q, you divide the result by the value of q: 28 / q.

The question asks to multiply 4 and 7 together, then divide by q. To do this, you first multiply the numbers together. 4*7 equals 28. You then divide this result by q. So, the final solution is 28/q.
