Answer:
5x + 13
Step-by-step explanation:
(3x + 9 ) + (2x + 4)
It's quite simple, we just have to add the parts that have x to each other and those that don't have x to each other
3x + 2x + 9 +4 =
then the result is
5x + 13
16 does not include all the factors because for the factors are 16:1,2,4,8,16
Well since the formula for the arithmetic mean is
thourgh
will be each of the numbers (2, 63, 88, 10, 72, 99, 38) and n would be the number of numbers being added. You have 7 numbers being added making n 7 so your equation would be
The answer is (1,1) Hope this helps :)
Given:
Hiroaki says that a constant of proportionality must be a whole number and cannot be a fraction or a decimal.
To find:
The explanation, why Hiroaki is incorrect.
Solution:
If y is directly proportional to x, then
where, k is the constant of proportionality.
It means, the constant of proportionality is the ratio of two directly proportional variables.
So, constant of proportionality can be any real.
Thus, the statement that a constant of proportionality must be a whole number and cannot be a fraction or a decimal is incorrect.
Hence, Hiroaki is incorrect because constant of proportionality can be any real.
