Answer:
The discount would be 25%
Step-by-step explanation:
24 and 18 are both divisible by 6
24 is just 4×6
18 is just 3×6
This means that 18/24 is the same as 3/4
We calculate the discount by subtracting the percentage of the sale price from the original price.
3/4 is the same as 75% of 100% meaning the discount percentage is 100-75, which gives us 25%
B=unknown number
answer:B b-45
Answer:
a = -8 + sqrt(10)/ 10
Step-by-step explanation:
-4log(a+8)=2
Divide each side by -4
-4/-4log(a+8)=2/-4
log (a+8) = -1/2
Raise each side to the power of 10
10 ^ log(a+8)= 10^-1/2
a+8 = 1/ sqrt(10)
Subtract 8 from each side
a +8-8 = -8 + 1 /sqrt(10)
a = -8 + 1/sqrt(10)
We do not like sqrt's in the denominator
a = -8 + sqrt(10)/ 10
Answer:
$535.25
Step-by-step explanation:
withdrawal means to take out (subtract)
$539.50- $35.50= $504
$504- 23.75= $480.25

Answer:
C
Step-by-step explanation:
Express - 1 as an improper fraction, that is
- x = 9 ( multiply both sides by 5 )
- 9x = 45 ( divide both sides by - 9 )
x = - 5 → C
