Answer:
215,00.
Step-by-step explanation:
Average price = 22500
18000*2 + 28000 + 27000 + x = 22500*5
91000 + x = 112500
X = 21500
The equation that best represent the actual prices of the skis is,
I x - 500 I ≥ 250
Solving the absolute value equation,
x ≤ 750 and x ≥ 250
Thus, the prices of the skis ranges from 250 to 750.
Answer:
option no (C) is correct
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
1/5x+4=1/3x-8
add 8 to both sides and subtract 1/5x from both sides
4+8=1/3x-1/5x
12=5/15x-3/15x
12=2/15x
divide both sides by 2/15
12÷2/15=x
when dividing by a fraction, invert and multiply
12*15/2=x
90=x
CHECK:
1/5(90)+4=1/3(90)-8
18+4=30-8
22=22
