Answer:
Age of ben = n years
Age of Chloe = 2n years
Age of Dan = (n - 5) years
Now,
Sum of ben, Chloe and Dan's age = t years
or, n +2n + n - 5 = t
or, 4n - 5 =t
This is the required formula
Answer:
416867.47
Step-by-step explanation:
to round the tenths, simply take the second digit of the decimal and look at the digit to its right, if its more 5 or more you round it up by one. if its less, simply ignore the numbers to the right.
Answer:
a number that is divisible by 10 is also divisible by 5 because 5 is a factor of 10.
Step-by-step explanation:
Given : Statement 'The relationship between numbers divisible by 5 and 10'.
To find : What statement BEST explains the statement?
Solution :
First we study the divisibility rules,
Rule for the number divisible by 5 is that number must end in 5 or 0.
Rule for the number divisible by 10 is that number need to be even and divisible by 5, as the prime factors of 10 are 5 and 2 and the number to be divisible by 10, the last digit must be a 0.
According to the divisibility rules Option D is correct.
Therefore, The correct statement explains the relationship between numbers divisible by 5 and 10 is a number that is divisible by 10 is also divisible by 5 because 5 is a factor of 10.
Hello from MrBillDoesMath!
Answer: line EF
Discussion: Two lines, L1 and L2, with slopes m1 and m2 are perpendicular if
m1 * m2 = -1. In our case m1 = -1/3 so the slope of the perpendicular line is 3.
( 3 * (-1/3) = -1). The line with slope 3 is rising as x gets larger. The only line shown fitting this is line EF. Note that line AB is "falling" as x increases so it can not possibly be the answer.
