Step-by-step explanation:
(1)1.75 + 3(3.75) - 4 = 23.5/4
23.5x/4 = 2.95
23.5x = 11.8
x = 0.5
Answer:
the correct choice is marked
Step-by-step explanation:
Let x represent the smaller number. Then the larger number is 8x, and the difference is ...
8x -x = 280
7x = 280 . . . . . simplify
x = 40 . . . . . . divide by 7
The larger number is 8x = 8(40) = 320.
