determine all possible digits to fill in the blanks to make each of the following true:

a. 63 is a factor of _543

There are no digits that make the proposition true.

Step-by-step explanation:

63 = 9 x 7.

Therefore we're looking for a number which is a multiple of 9 AND a multiple of 7.

To know if a number is divisible by 9, the sum of its digits has to be either 9 or a multiple of 9.

So, we're going to sum up the digits we have so far: 5 + 4 + 3 = 12, the only digit that would give us a sum that's a multiple of 9 is 6 (because the sum would be 18). The number then would be 6543.

But this number is not a multiple of 7: 6543/7 = 934.71 and therefore it's not a multiple of 63.

Therefore, there are no digits to which the number _543 is a multiple of 63.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
