Garfield had $10 in the bank yesterday. Then, Garfield bought dinner for $14, but didn't realize that he overdrew from his bank.

I believe it’s 4 since he’s in dept with 4 dollars so that’ll be -4, but the absolute value is 4 since it’s 4 spaces away from 0.

Twice the difference of a number and 9 equals 8
ladessa [460]

Answer:

13 is the number.

Step-by-step explanation:

Given:

Twice the difference of a number and 9 equals 8.

Let the unknown number be 'x'.

Therefore, as per question:

The difference of 'x' and 9 = x-9

Twice the difference means 2 times the difference. So, we multiply 2 to the difference. Therefore,

2(x-9)

Now, the above expression is equal to 8. So, we equate the above expression to 8. This gives,

2(x-9)=8

Solving for 'x', we get:

Using distributive property of addition and distributing 2 inside the bracket. This gives,

2\times x-2\times 9=8\\\\2x-18=8\\\\2x=8+18\\\\2x=26\\\\x=\frac{26}{2}=13

Therefore, the unknown number is 13.

Now, we can verify our answer.

2(13-9)=26-18=8

Therefore, the answer is correct.
