So as seen in the previous problem and using the associative propery of multiplication which is a(bc)=(ab)c we can conclude that the order doesn't matter so then we find the part with the positives and negatives
so we will see what happens when we multipliy positives and negatives
so we remember these rules
(+)=positive
(-)=negative
(+) times (+)=(+)
(-) times (-)=(+)
(+) times (-)=(-)
(-) times (+)=(-)
basically group in pairs and write the signs down to conclude proper signs ex.
-2 times 2 times 4 times -3 would be (-2 times +2) times (+4 times -3) or (- times +) times (+ times -)=(-) times (-) =+
basically just do this over and over again untill you get 1 sign
basically the rule is if you multiply 2 pairs of signs, if the signs are the same, then the result is positive
if the signs are different, then the result is negative
(+) times (+)=(+)
(-) times (-)=(+)
(+) times (-)=(-)
(-) times (+)=(-)
Answer:
0
Step-by-step explanation:
Joe had 5 and Mary had 5.
The amount each person has is equal. They don't have more or less than each other. So it's 0.
(5/4) / (2/3)
= 5/6
therefore: he has run 5/6 miles so far
Answer:
The answer is that adult tickets cost $44.50 and child tickets cost $19.
Step-by-step explanation:
Let c = the cost of child tickets and a = the cost of adult tickets.
The total amount is equal to the number of adult tickets time the cost of adult tickets plus the number of child tickets times the cost of child tickets. Set up two equations:
2a + 4c = 165
4a + 3c = 235
Solve the top equation for a:
2a + 4c = 165
2a = 165 - 4c
a = 165/2 - 4c/2
a = 82.5 - 2c
Substitute into the second equation:
4a + 3c = 235
4(82.5 - 2c) + 3c = 235
330 - 8c + 3c = 235
-5c = -95
c = -95 / -5 = 19, so child ticket cost $19.
Solve for a:
a = 82.50 - 2c
a = 82.50 - 2(19)
a = 82.50 - 38
a = $44.50, so adult tickets cost $44.50.
Proof using the first equation for the Johnson family:
2a + 4c = 165
2(44.50) + 4(19) = 165
89 + 76 = 165
165 = 165
Proof using the second equation for the Robison family:
4a + 3c = 235
4(44.50) + 3(19) = 235
178 + 57 = 235
235 = 235
