Answer:
Number of students van can carry = 11
Number of students bus can carry = 41
Step-by-step explanation:
Given the following :
HIGH SCHOOL A:
Number of students = 184
Number of vans(v) = 13
Number of buses(b) = 1
Mathematically,
13v + 1b = 184 - - - - (1)
HIGH SCHOOL B:
Number of students = 520
Number of vans(v) = 10
Number of buses(b) = 10
Mathematically,
10v + 10b = 520 - - - - (2)
Multiply (1) by 10 and (2) by 1
130v + 10b = 1840 - - - (3)
10v + 10b = 520 - - - (4)
Subtract (4) from (3)
120v = 1320
v = 11
Substitute v = 11 into (1)
13(11) + 1b = 184
143 + b = 184
b = 184 - 143
b = 41
Number of students van can carry = 11
Number of students bus can carry = 41
Answer:
12
Step-by-step explanation:
Since 10x4=40, and 14x4=56, then all you have to do is multiply 3 by 4, to get 12.
Say x = the number of items being purchased. Then we can write the equation, using seconds:
3x + 16 = 136
(3 seconds per item, plus 16 seconds to process payment, equals 136 seconds total.)
Subtract 16 from each side. Then divide both sides by 3.
Answer: 2
Work: Substract 28.5 minus 20.5 = 8
Then substract 9 - 5 = 4
Then put them as a fraction like 8/4
Put it as a unit rate or divide 8 by 4 and that equals 2.
Hope it helps!
