Answer:
7 groups, 3 boys and 8 girls
Step-by-step explanation:
Let total number of groups be 
and total hikers in one group be 
if number of girls and boys in every group is same, then
....(1)
from (1) will either be 11 or 7
for 
the values won't be real.
For 
so there will be 7 groups with 11 hikers in each groups and every group will have 
boys and 
girls
8(4a+2b)
The equivalent is 32a+16b (B)
The graph is misleading because the year’s interval is not constant.
The first year to the second year, the gap is 1 year; in the second to the
third year, the gap is 2; in the third to the fourth year is 4; and the fourth
to the fifth year is 6.
Use the slope-intercept y=mx+b to find slope
Slope=m
M=3
