23 less than 7 times a number is greater than 43

x>-2.8571428571 to be exact, but you can round it to the hundredth decimal which is -2.86 or round it to the tenth which is -2.9

Step-by-step explanation:

23-7x>43

1: do the inverse operation: 23-23=0

2: do that to the other side as well: 43-23=20

Your new inequality is: -7x>20

3: divide both sides by -7: -7x/-7= x, 20/-7=-2.8571428571

Your final answer can be either the inequality problem (23-7x>43) or the answer to the inequality problem(x>-2.8571428571)

answer: 140

step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
