Answer
Find out the what is the number of weeks that have passed since since jeffrey had $250 .
To prove
Let us assume that the number of weeks be x .
As given
Jeffrey has $250 in the bank.
Each week he takes out $25.After a few weeks jeffrey has $87.50 left in the bank.
Than the equation becomes
87.50 = 250 - 25 x
87.50 = 250 - 25x
250 - 87.50 = 25x
162.5 = 25x
x = 6.5 weeks
Therefore it take 6.5 weeks (approx) that have passed since jeffrey had $250 .
The slope of a perpendicular line is the opposite reciprocal
so the slope, 6, will become -1/6
Answer:
No
Step-by-step explanation:
We can't use 2x + c = d for solving 2x + 1 = 9 . Here we can find the value of x from 2x + 1 = 9.
Putting the value of x in 2x + c = d :-
But still we don't know the exact value of c & d . If in the question at least we could have got one exact value of either c or d , then we could find out the value of other variable.
Answer:
The correct answer to this problem is the third statement which is "Alexia completed 20 math problems and 10 science problem". The following conditions are stated in the problem:
Alexia can answer 3 minutes on each math problem
Alexia can answer 4 minutes on each science problem
She worked more than 60 minutes
We have the inequality 3x + 4y > 60 where x represents the total number of math problem while y represents the total number of the science problem.
in our answer, we have x=20and y=10
3*20 + 4*10 > 60
60 + 40 > 60
100 > 60
