Divide the numerator and denominator by 21:
21 / 21 = 1
84 / 21 = 4
So 21/84 is equal to 1/4.
Well

translates to

so
log5(x/2)=5 means 5^5=x/2, so 3125=x/2, so 6250=x
Answer:
25% of 1000 is 250
Step-by-step explanation:
(<u>25 ÷ 100</u>) × 1000
Divide the numbers
<u>0.25</u> × 1000
<u>0.25 × 1000</u>
Multiply the numbers
<u>250</u>
250
It’s actually all except bottom left
Answer:
<u>The first option is </u>
<u>The second option is:</u>
- B(0) = 1000
- B(1) = 1100
- The ratio is 1.1 and the zero term is 1000
<u>The equation for this option is:</u>
Now, which option is better?
It depends on the number of x. It is assumed the genie is offering money or similar reward.
For the values of x below 50 option A is better and option B is much better for x > 50.
See the graph in the attachment, where green line represents the option A and red line is option B.
