1. is false
3. is 5
4. 17.5
someone else can get the other two.
Answer and Step-by-step explanation:
The cost of all the 6 magazines are: 6x
The cost of all the 9 newspapers are 9(x-3)
So, the total cost is the sum of all the items:
6x + 9(x-3) = 51
6x + 9x - 27 = 51
15x = 78
x = 5.2
Since the cost of one magazine is $x, the cost will be $5.20.
In order to check the different representations, we first simplify the inequality:
6x ≥ 3 + 4(2x - 1)
6x ≥ 3 + 8x - 4
1 ≥ 2x
<span>1/2 ≥ x
Looking at the simplification process, we see that the first and second options are correct representations. Moreover, if we plot the simplified inequality on a number line, then we see that the third representation is also correct. Therefore, the first, second and third representations of the inequality are correct.</span>
It tells you in the question, 5 min for the larger conveyor belt and 6 for the smaller one, unless you are saying that it divides the weight equally then it would be half the time for both
