Answer:
25 people were surveyed.
Step-by-step explanation:
Add up the frequency.
The answers are expressions:
(7b*3)+(7b*c)
21b+7bc
I hope I helped!
Step-by-step explanation:
-10x+-4x-15/10+-14x-5
-14x-15/5-14x
+14x. +14x.
-15 does not equal 5 no solution
The next number would be 19.
Each number adds one more each time.
For example, 4+0=4, 4+1=5, 5+2=7, 7+3=10, 10+4=14, 14+5=19
Hopefully this makes sense, its kind of hard to explain.
Hope this helps :)
