Answer:

160

Step-by-step explanation:

If out of 30 7th graders, 12 own a dog then when you have 400 of them, 160 will have a dog as well.

The way I did this was by 400/30: which was 13.3 repeating. I then mutliplied this number by 12, to find the final answer of 160.

5th grade math. Correct answer will be marked brainliest.
dybincka [34]

Answer:

Trevor read 157.5 pages this week.

Step-by-step explanation:

Simple multiplication.

Multiply 5 by 5 first to get 25, carry the 2 on top and then multiply 3 by 5 to get 15, make sure to add 2 to get 17.  The first line should be 175.

Put a 0 on the last digit to solve for the next digit.  Multiply 4 by 5 to get 20, carry the 2 on top and then multiply 3 by 4 to get 12, make sure to add 2 to get 14.  The second line should be 1400.

Add the numbers up to get 1575, since there is one number behind the decimal, you should put a decimal in front of the last 5 for the answer in which it is 157.5.

GEOMETRY If one point is located at (–6, 2) and another point is located at (6, –3), find the distance between the points.
notka56 [123]

Answer:

It should be 13 units.

Step-by-step explanation:

In the picture shown, the two red dots are the coordinates (-6, 2) and (6, -3). The smaller light blue dots is the distance from one red dot to the other red dot. I counted  17 units between the two and using a ruler, I  estimated 12 units. In conclusion, it should be roughly 13 units. I hope this helps! If this is not the right answer, I would love to recieve some feedback of what I did wrong! Thank you!
