Answer:
3m+3p
Step-by-step explanation:
Sum of m and p is expressed as;
m + p (sum means addition)
If 3 is multiplied by the sum, this is expressed as;
3(m+p)
Expand
3m + 3p
Hence the required expression is 3m+3p
This is a ratio.
12 km : 3 h
simplify to-
4km : 1 h
which means the hiker traveled 4 km per 1 hour.
Subtract 20 from the total weight and divide by 4:
200 - 20 = 180
180/4 = 45
Each other crate weighs 45 pounds each.
There are approximately 14 halves
