30 * x = 245
lets divide 30 and 245, 245 / 30 = 8.167
8.167 x 30 = 245
hope it helped
5x5x5=125 so it could be x=5
For <u> the following subtraction problems 17t 13lb 3oz - 9t 20lb 9oz the output is oz = 7 T 1992 lb 12 oz</u>
Step-by-step explanation:
Let us first consider that
<u>1 T = 2,000 lb</u>
<u>1 lb = 16 oz</u>
Here we will convert all the measure units to oz, subtracted the amounts, and finally converted the units back to their original ones.
<u>17t 13lb 3oz - 9t 20lb 9oz (The equation given to us)</u>
<u>It can be rewritten as </u>
=17 T or (2,000 lb*17) + 13 lb + 3 oz) - (9 T or (2,000 lb*9) + 20 lb + 9 oz)
= (34,013 lb or (16 oz *34,013) + 3 oz) - (18,020 lb or (16 oz *18,020) + 9 oz)
= 544,213 oz - 288,329 oz = 255,884
<u>oz = 7 T 1992 lb 12 oz</u>
A perfect square is a number which contains a a factor that involves a number multiplied by itself. You could also say a perfect square, when taken the square root of such a number, involves a whole number answer. Either explanation would work, and there are surely mainly more haha. 25 is the perfect square because 5×5 is a factor of 25, while 50 doesn't have a factor of the same numbers.
