Answer:
median= 6.5
Step-by-step explanation:
6= 2+5+x+1+x+2+7+9/6
summing up the values
26+2x=36
collecting like terms,
2x=10
divide both sides by 2
x= 5
5+1=6
5+2=7
so the numbers are 2 5 6 7 7 and 9
the median = 6+7/2
= 6.5
Answer:
x= 25/3 or 8.333333
Step-by-step explanation:
you add 11 to 10 to get 21
3x-4=21
add 4 to both sides, which will cancel out the (-4)
3x=25
divide each term by 3 to get x by itself
3x/3 = 25/3
you will then get x=25/3
All numbers that only have one and itself as factors are prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
Answer:
0.9265x
Step-by-step explanation:
x - 0.15x + 0.09(0.85x)
x is the initial amount, -0.15x is subtracting 15% of the original amount (leaving 0.85x), and 0.09(0.85x) is the 9% tax.
Simplified:
x - 0.15x + 0.09(0.85x)
= 0.85x + 0.0765x
= 0.9265x
50% is equal to the so we can easily divide 9 by 2 to get your answer 4.50 there is no hundreths for it is a clean divide (4.5×2=9)
