4a + 7b = 38 -> (1)
9a + 7b = 68 -> (2)
Subtract (1) from (2),
9a - 4a + 7b - 7b = 68 - 38
5a = 30
a = 6
Answer:
-3n
a10= -30
Step-by-step explanation:
the distance between -3 and -6 is 3.
if you multiply 3 by the 1st term, it's just 3, so the 3 needs to be a -3.
For a10, you plug in 10 into the equation which is -3n. and that is -30.
3 adults and 5 kids.
You can get this by setting up the following system of equations.
x + y = 8 (number of people)
10x + 12y = 86 (cost)
A) the median is the middle measurement. Their ages could be 13, 14 and 15.
B) 2 students must be younger than 13
C) Like I said, the median is the middle measurement. If you have a list of numbers, you have to order them and take the middle number.
