Answer:
-5.2, -4.75, -9/2
Step-by-step explanation:
2x-1+3x+15+9 so you are going to add 2x and 3x so that will be 5x+-1+9+15
-1+9=8+15=23 so that will be 5x/23 that will be 4.6
When you're writing things in scientific notation, the new spot for the decimal number always goes in between the first and second numbers that are not zeroes. For this problem, it'd be 1.4. Then, count how many times the decimal place moves to get to the new spot (#power of ten), which in this case is 4 times. The way I remember this next part is that if it has a negative exponent, the number you get when you solve is really small, so therefore the answer is 1.4×
