Hello from MrBillDoesMath!
Answer: Choice "B", which is 3
Discussion:
The consecutive integers <= 7 are
1,2,3,4,5,6,7
4 is the largest number in this list that makes sense in this problem (for example, 5 + 6 > 7, 7 + 6 > 7 don't satisfy the problem)
1 + 2 = 3 <= 7
2 + 3 = 5 <= 7
3 +4 = 7 <=7 (*)
The lesser integer in the last equation (*) is 3
Thank you,
MrB
It would Be D. 6/7 and 15/7. Like fractions are fractions with the same denominator. So The answer would be D.
X is the amount Micheal has so the answer is X>20 because he has more than 20
To solve systems of equations you have 3 ways: Substitution, Elimination, and Graphing.
For graphing you could use desmos or a graphing calculator.
For substitution, you solve for x or y on one of your equations and, for example, let's say you solve for x, you take whatever x equals to (EX. x=y+2) and plug it into your other equation (EX. 3(y+2)-y=3)
For elimination, get x or y to be the same number but opposites (one positive one negative) then you "add" the two systems together and then you should end up with #x=# or #y=#, (EX. 2x=6) last step is to divide.
Hope this helps
Let x = number of weeks.
815 - 35x ≥ 150.
Subtract 815 from each side
-35x ≥ -665
Divide each side by -35
x ≤ 19
He can withdraw $35 every week for at most 19 weeks.
