You need his sisters age to solve the problem. if y is the sisters age and x is Johns age, then the equation is
3y-2=x
Answer:
Step-by-step explanation:
Let
n ------> a number
we know that
The algebraic expression that represent the phrase"5 less than a number" is equal to subtract 5 from the number or a number minus 5
so
Answer:
2/10
Step-by-step explanation:
If you are trying to find out the probability of a number just know that the whole number is always going to be the denominator. In this problem, the denominator is <em>10</em> because that is the whole number of pieces of paper.
Then we look at the second part of the problem where it is asking us to figure out the probability of pulling out a number that is less than 3 which would only leave us with <em>1-2 </em>
This means that the probabilaty of pulling out a number less than 3 is <u><em>2/10</em></u>
Log of 0 or <0 does not exist
so x + 6 must be > 0
so the domain is (-6, +infinity)
or x > -6
