5x+4<54
subtract 4 from both sides
5x<50
divide both sides by 5
x<10
Answer:
x²+(1/x²) = 47
Step-by-step explanation:
by identity : (a+b)² = a²+b²+2ab
(x+1/x)²= x²+(1/x)²+2(x)(1/x)
(x+1/x)²= x²+(1/x²)+2....(1)
since : (x²+1)/x = 7
(x²/x) +(1/x) = 7
x + (1/x )= 7
put the value for : x +(1/x) in (1) :
49 = x²+(1/x²)+2
x²+(1/x²) = 47

Answer:
B. cost(time)
Step-by-step explanation:
In the information given above, you can eliminate choices "A," and "D," since they're just using the cost of a repair and the time the mechanic works. This leaves us with either "B," or "C." The correct answer is "B," because the cost of the repair depends on whatever is inside the parenthesis (the time).
For the answer to the question above asking what was the cost of each file folder if Thomas paid $50 for a box of the multicolor file folder for his office, there were 100 folders in the box?
this is a grade 2 problem. If you know how to divide you will get the answer.
Just d<span>ivide $50 by 100. Then you'll get the answer. </span>
