Hello there! I can help you! The number shows is 24 ten millionths. It is in decimal form, so the exponent for the power of 10 will definitely be negative. The first number has to be greater than or equal to 1, but less than 10. If we look at this number and you place the decimal between the 2 and the 4, we can use 2.4 as the front number, because it's greater than 1, but less than 10. Now, we can move that decimal to the left a certan number of times to get that number shown below. If you count from the decimal, you move to the left 6 times. That makes the power of ten 10^-6. And when you multiply 2.4 * 10^-6 (0.000001), you get 0.0000024. There. The number in scientific notation is 2.4 * 10^-6.
1) Jane is (x - y) years old
2) Anna was (x - 3) years old 3 years ago
3) Jane will be (x - y + 5) years old in 5 years
4) The sum of their current ages is (2x - y) years
Answer:
b
Step-by-step explanation:
I got u! (numerator)/(denominator)
* ^2 : squared
*^3 : cubed
1a) (5x^2-11x-9)/(x^2+5x-24)
1b) (-4x^2-6x-6)/(x^3+x^2-9x-9)
1c) (16x^3)/(y^2)
1d) (1)/(x+3^2)
