For this case we must raise an inequality.
We have "d" dollars initially and they are spent 12. Then:
At least 51 dollars remain, then, the sign of inequality is greater or equal in favor of the expression, that is:
Resolving:
There are at least 63 dollars left in the account.
Answer:
Solve by substitution
Just plug in y=-x-1 into y+x=3
So we get:
Simplify that:
And since that is not true, that means this system of equations has no solutions!
W will be at the points (-6,-2) after 180 degrees counterclockwise rotation
Answer:
Michael = x÷7
lee = 2(x÷7)
(x÷7)+2(x÷7)
Step-by-step explanation:
since he earns x dollars every seven days, to get the amount he earns, you divide that amount by 7 and for Lee, she gets twice as much so you multiply Michael's amount by 2
