Answer:
D) (0.59, 3.35)
Step-by-step explanation:
The inequality for the thickness of the metal bars is:

In order for this inequality to be true, the following conditions must be met:

The range of thickness "x" that fits the inequality is:

Thickness ranges from 0.59 to 3.35 units.
TRUE. I don't know for other languages, but in English you surely can do that.
Answer:
No, it is not.
Step-by-step explanation:
The set
contains every ordered pair of Natural numbers, while B only contains those pairs in which both values in each entry are the same. Therefore, C is a bigger set than B, but B is not equal to C because for example C contains
and B doesnt because 1 is not equal to 2.
X = shorter piece
y = longer piece = 5x
shorter piece + longer piece = 60
x + 5x = 60
6x = 60
x = 60/6
x = 10 in. <== shorter piece
y = 5x
y = 5(10)
y = 50 in. <== longer piece
12 and 3/10 more than 5 and 13/1000 of d equals 15 and 302/1000
12 and 3/10+(5 and 13/1000 times d)=15 and 302/1000
convert to improper fractions
12 and 3/10=123/10
5 and 13/1000=5013/1000
15 and 302/1000=15302/1000
123/10+(5013/1000 times d)=15302/1000
subtract 123/10 from both sides
123/10=12300/1000
(15302-123000)/1000=2698/1000
5013/1000 times d=2698/1000
multiply both sides by 1000/5013 to clear fraction
d=2698/5013
