Step-by-step explanation:
Draw your figures the same way as I did, and see if you understand the explanations before writing them down. It's most important to learn from your work :)
Answer:
6.75 × 10^3
Step-by-step explanation:
Move the decimal 3 times to the left so that the resulting number, m = 6.75, is greater than or equal to 1 but less than 10
Since we moved the decimal to the left the exponent n is positive
n = 3
Write in the scientific notation form, m × 10^n
6.75 × 10^3
Answer:
18
Step-by-step explanation:
6(7e+3)=6*7e + 6*3=42e + 18
So we have ratio 5/7, and sum is 168, so clearly numbers are not 5 and 7 since 5 + 7 = 12, not 168, so ratio is 5x / 7x, where x is unknown number.
So now we can set up sum: 5x + 7x = 168
12x = 168
x = 168 / 12 = 14
So our two numbers are 5x and 7x, which are 5 * 14 = 70 and 7 * 14 = 98
So the answer is 70 and 98
