Answer:
15
Step-by-step explanation:
3 2/4+ 2 3/4+ 2 3/4+ 2 1/4+ 1 1/4+ 1
first add the whole numbers so 3+2+2+2+1+2=12
then we are left with the fractions. 11/4 divides into 2 with a remainder of three so we add it to the top.
From here we have 2/4+3/4+3/4+1/4+3/4
add them together and we get 12/4=3. Then add back our whole numbes to get 12+3=15
Answer:
x=-2.5,9
Step-by-step explanation:
Set them equal to each other to say 2x^2-9x=4x+45. Get them all on one side to get 2x^2-13x-45. Factor that out to get (x+2.5)(x-9). Set that equal to 0 to get x=-2.5,9
