The answer is 2.45 x 10^5.
7 x 3.5 = 24.5
Move the decimal place over to the left until you have a number between 1 and 9 before the decimal point.
Add the number of times you moved the decimal point to the exponent (The 4 in the original equation).
2.45 x 10^5.
I hope this helps!
If they're similar it would be 72, 36x2=72.

45+36+20=101
Answer:
45
Step-by-step explanation:
5 less than your number is at least 40. Let the number be x. So rephrasing the statement, 5 less than x is greater than or equals 40.
x-5 ≥ 40
x-5+ 5 ≥ 40+5 (adding 5 to both sides to single out the x in LHS)
∴x ≥ 45
In other words, x is at least 45.
Therefore, the minimum value of x is 45.
You can solve this by convert mixed number(s) into improper fraction(s) 2. change both fractions to the equivalent fractions with the same denominator 3. omit denominators and write numerators as a ratio 4. simplify the ratio by dividing both numbers by the highest common factor.
