Answer:

x = 22

Step-by-step explanation:

4(x + 2) = 96

Use distributive property : a(b + c) = a*b + a*c

4*x + 4*2 = 96

4x + 8    = 96

Now subtract 8 from both sides.

4x  = 96 - 8

4x = 88   {Divide both sides by 4}

x = 88/4

x = 22

The four digit numeral 3AA1 is divisible by 9. What digit does A represent
dexar [7]

Answer:

A = 2, the number is 3221

Step-by-step explanation:

In order for the number to be divisible by 9, the sum of it's digit has to be divisible by 9.

In our case, 4+A+A+1= 9k where k is an integer. the easiest way happens when k=1

5+2A= 9 \rightarrow 2A=4 \rightarrow A = 2

Higher values of k will likely most work (with k=2 you get A to be a non-integer, which can't work since it's the digit of a number, and with higher values of K you're not getting a number in base 10.
