Um I think it's like because there's a zero difference like ten thousands have more zeros
plugging x=-2 in the given equation we get
=12/3²
=12/9
=4/3
so answer is 4/3
The equation would be written like this 2x-10=48. First add 10 to both sides so 2x-10+10=48+10 so simplified that is 2x=58. Now, divide both sides by 2 to get x by itself so it will look like this 2x/2=58/2 simplified that is x=29. I hope this helped you.
Answer:
9
Step-by-step explanation:
Let the number be n.
Then: 4n + 15 = 6n - 3
Subtract 4n from both sides, obtaining: 15 = 2n - 3
Now add 3 to both sides, obtaining 18 = 2n. Then n = 9.
Answer
Find out how many seconds faster has Alexandria's time then Adele's time .
To proof
Let us assume that seconds faster has Alexandria's time then Adele's time be x.
As given in the question
Adele Swam the length of the pool in 32.56 seconds. Alexandria swam the length of the pool in 29.4 seconds.
Than the equation becomes
x = 32.56 - 29.4
x = 3.16 seconds
Therefore the 3.16 seconds faster has Alexandria's time then Adele's time .
Hence proved
