63 ÷ 3 = 21.
Well 63 divided by 3 equals 21. So 3 times 21 equals 63. 21 is that number.
3 x 7 = 21
How about: 1*21 = 21 or 3*7 = 21
3 times 7...
21 times 3 equals 63
3 x 21 = 63
The number 3 can go in to 63 21 times. 63 divided by 3 equals 21.
To solve the equation 9x = 21, you would first need to isolate the variable x by dividing both sides by 9. This would give you x = 21/9, which simplifies to x = 7/3 or x = 2.33 (rounded to two decimal places). Therefore, the value of x that satisfies the equation 9x = 21 is x = 7/3 or x = 2.33.
How about: 3 times -7 = -21
3 x 7
21/3 does.
