Hi
Stephen and his five friends = 6 people at the restaurant
Let's call X the amount of the bill.
so if X/6 = 13.21
X = 13.21 * 6
X = 79.26
Answer:
You distribute the 2 to all numbers in the 3rd step
Step-by-step explanation:
DISTRIBUTION: you must distribute the outside number to all the inside numbers in the parentheses.
Since a and b have opposite signs then both the product and quotient will be negative. The absolute value of a · b will be greater than the absolute value of 
.
Without the absolute value sign, then since both the product and the quotient are negative, a · b <
Answer: the product is less than the quotient

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
