12x+9= 45, x =3 3 is the answer
What a problem! We know that the largest digit is 8,000, and the smallest is 0.01. The number is 8,_ _ _._1. If the tens is 2 less than the hundreds digit, then if we make the hundreds digit x, the tens are x-2. The tens digit plus the hundreds digit is the thousands digit, so x+(x-2)=8. Let's solve: x+(x-2)=8. Eliminate parentheses: x+x-2=8. Use inverse operations:x+x-2+2=8+2. x+x=10. Combine terms: x+x=2x. 2x=10. Divide: 2x/2=10/2. x=5.
So the hundreds digit, x, is 5. And the tens are x-2: 5-2=3. The number is 8,53_._1. And what's the only number that means the same, no matter what place value you put it in? 0! This is the tenths place: 8,53_.01. The remaining digit is the ones. The largest one-digit even number is 8, so our number is 8,538.01!
Answer: 8,538.01
There are 17,576 combinations.
There are 26 letters to choose from for the first letter; 26 for the second letter; 26 for the third letter; and 1 for the last letter (it must be the same as the first letter). This gives us
26*26*26*1 = 17576

➷ 847) You need to cross multiply
Multiply both sides by (x - 7) and 3
This is what you should get:
Now we just need to get like terms on the same side.
Add 42 to both sides and subtract 2x from both also
Now you get this:
848) It's the same principle in this one too.
Multiply both sides by (x - 13) and 11
You should get:
Subtract 11x from both sides and add 156 also
Now you get:
849) Multiply both sides by x
You should get:
Add 4x to both sides and add 12 also:
Divide both sides by 5
850) Multiply both sides by x
You should get:
Subtract x from both sides:
Divide both sides by 3:
