Check the attached file for the answer.
(4 3/4) + (5 3/4) = (4 + 5) + (3/4 + 3/4)
= 9 + 2×(3/4)
= 9 + 3/2
= 10 1/2 . . . . pounds of tomatoes
A -17 3/4< x so u have to simplify-17 3/4 by multiply 17*4=68+3=71/4 so the x stands for -71/4 and it has to be 4 as the denominator because it it the denominator for the question.
B, C, D are also the same answer-17/4
And for 15 3/4<-2+ x it is also the same answer
12=5x-13x-44
combine like terms
12 = -8x -44
add 44 to each side
12+44 = -8x
56= -8x
divide by -8 on each side
56/-8 = x
-7 =x
