HELP!!! Carbon dating is used to determine the age of fossils. A fossil was found with 75% of the original carbon-14. The half-life of carbon-14 is 5,730 years. The equation that models the situation is 0.75=(0.5)x5,730.
How old is the fossil?

D. x≈2,378

To which sets of numbers does -12 belong? choose all answers that are correct. a) natural numbers b) integers c) real numbers d) irrational numbers

Two times a number plus three times another number equals 4. three times the first number plus four times the other number is 7. find the numbers

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
