Answer:
Length between the longest bolt and the shortest bolt is:
2.375 inch
If we laid one of each size bolt end to end , then the length of row of bolts is:
5.125 inch
Step-by-step explanation:
We are given that:
Martin sorted the bolts in his toolbox by size.
They measured 3/8 inch, 1/2 inch,5/8 inch, 7/8 inch, and 1 1/4 inches
longest bolt= 11/4 inches shortest bolt=3/8 inch
Difference between longest and shortest bolt= 
Now, if we lay one of each size bolt end to end then, length of row will be:

=41/8
= 5.125 inches
Answer:
33
Step-by-step explanation:
Answer:
x[ 11y + t(5 - x)].
Step-by-step explanation:
7xy - x^2t + 4xy + 5xt
= 7xy + 4xy + 5xt - x^2t
= 11xy + 5xt - x^2 t
= x(11y + 5t - xt)
= x[ 11y + t(5 - x)].
71614 is the answer, this can be found by simply solving this expression: 72000 - 386
