Answer:
its b
Step-by-step explanation:
6 - 1/2z = 2/3
Steps
First, subtract 6 from both sides
6 - 1/2z - 6 = 2/3 - 6
Then, simplify
-1/2z = -16/3
Then, multiply both sides by -2
(-1/2z) (-2) = (-16/3) (-2)
Then, simplify
z = 32/3
They have the same amount on week 5 ($70)
The Answer would be: $70
((Got this correct on my quiz, If you need it explained, It is below))
The easiest way to do this is to not pay attention to the y=x equation, because the solution is already in the information, this may confuse you and youre wasting time to solve it. Jess has $20 BEFORE saving and gets $10 WEEKLY, Raph has $40 BEFORE saving and gets $6 WEEKLY. In the chart/information, add the amount it takes to get Jess up to $40 then add $10 for every week on going until both their balances are equal. They match on the 5th week with $70 // If the information is different substitute the names/numbers/etc. Hope this helped you and anyone else looking for the answer!
Answer:
130°, 50°, 130°
Step-by-step explanation:
Two opposite angles of parallelogram are always congruent, so the measure of angle opposite to the angle 50° is 50° too.
Two consecutive angles of parallelogram always are supplementary (add up to 180°), so the angle consecutive to the angle 50° has the measure of
180° - 50° = 130°
Angle opposit to 130° angle has the measure of 130° too.
A is a permutation since order matters.
B is also a permutation. Order matters here.
C is yet another permutation.
D is a combination because the order of towels doesn't matter.
