Answer:
10
Step-by-step explanation:
There is a way to turn this into a simple equation, but I will not go through that.
So the conditions are saying the first term is 40 and for every term after that you multiply the last by .5. So to get the fifth you would multiply the fourth by .5.
We want the third, so we need to multiply the second by .5. To get the second we multiply the first by .5. since the first is 40, 40*.5=20. Then just repeat.
Answer:
7=6/5r +12/5
Step-by-step explanation:
If 12 students make up 24% of the population, 1 student is 2% of the population because 24/12=2
100/2%=50
I did this because the population would be 2% times # of students= 100%
divide 100 by 50 to get 2 percent or 100/ 2 percent to get 50 students
Answer:
$37
Step-by-step explanation:
Delivery fee- $10
each sandwich- $4.50
Sandwiches ordered- 6
4.50(6)+10=37
Discount %= 10%
Discount= x × 10%= x/10
Price after discount =x-(x/10)= 9x/10
But, given price after discount = rs 450
9x/10=450
9x=4500
x=4500/9= rs 500
