Answer:
what is the question?
Step-by-step explanation:
Answer: $9
Step-by-step explanation:
Let the cost for adults be a
Let the cost for students be b.
The first van transported 2 adults and 5 students and cost $77. This will be:
2a + 5b = $77
The second van transported 2 adults and 7 students and cost $95. This will be:
2a + 7b = $95
2a + 5b = 77 ...... equation i
2a + 7b = 95 ........ equation ii
Subtract equation ii from I
-2b = -18
b = 18/2
b = $9
An student cost $9
Put the value of b into equation i
2a + 5b = 77
2a + 5(9) = 77
2a + 45 = 77
2a = 77 - 45
2a = 32
a = 32/2
a = 16
An adult costs $16
The answers would be -8 and 18
-8×18 = -144
-8+18 = 18-8 = 10
Answer:
Step-by-step explanation:
Least to largest:
First compare the whole parts of the decimal number. The whole part with greater number will be the greatest number.
2) Then compare the decimal parts. Compare tenth place. The decimal number that has greater number in the tenth place will be greater.
3) If the number in tenth place is equal, then compare 100th place and so on
