The formula for area of a parallelogram is a=b•h
a=42•28=1,176
Ok so Mr gals takes 7 hours and Mr Lee's takes 6.25 hours to mow and those added equal 13.25 so 63 divided by 4 equals 15.75 so if we take that and minus gal and Lee's lawn it takes 2.50 hours to mow Mr unknowns lawn
Answer:
1.) 6
2.) -1
3.) 36
4.) 1/3
5.) 90
Step-by-step explanation:
1.) -12/a
-12/a -> -12/2
=6
2.) a+ (-b)
a+(-b) -> 2+(-3)
=-1
3.) 3a (12-2b)
3a(12-2b) -> 3(2) (12-2x3)
6(12-6)
6(6)
=36
4.) 2a-c/b
2a-c/b -> 2(2)-5/3
4-5/3
=1/3
5.) 3abc
3abc-> 3x2x3x5
=90
