Answer:
3a-21
Step-by-step explanation:
You multiple 3 with the inside of the parenthesis. 3 time a = 3a and 3 times negative 7 is -21
Answer:
-1
Step-by-step explanation:
Given a pair of points, we can find the slope from the following formula
m = (y2-y1)/(x2-x1)
= (0--4)/(-2-2)
= (0+4)/(-2-2)
= 4/-4
= -1
Step-by-step explanation: look so if you have
shcool A its 8v+4b=12
and
School B: 12v+4b= 16
since both classes used 4 busses we can use elimination by subtracting the A class Equation from the b class equation to solve from v for its value Then, use either equation and the now found value for v to solve for b.
You should find part of the process to be
12v+4b-(8v+4b)=12-16 which shows the van holds only a few people even before continuing the solution.
