Answer:
a = -2
Step-by-step explanation:
-3a + 8 = 14
First you want to combine the constants by subtracting 8 from both sides.
-3a = 6
Now you want to isolate a by dividing both sides by -3.
a = -2
Check your answer by plugging -2 back into the equation.
-3(-2) + 8 = 14
6 + 8 = 14
14 = 14
Your answer is correct.
Hope this helps!
Answer:
6682
Step-by-step explanation:
So we have a 4 digit number and we need to find all the digits of it.
First, we are told that the one digit is 2. So the number is xxx2
Now, we know that the tens digit is 4 times greater than the ones, thus, the tens digits is 4 times 2, this is 4(2) = 8. Thus, the tens digit is 8 and the number is xx82.
Finally we know that the hundreds and thousands are both 3 times greater than the ones, so the digits are 3(2) = 6. Thus the hundreds and thousands are 6 and the final number is 6682.
