Answer:
20
Step-by-step explanation:
To get to -10 from 5 you have to subtract 15
to get to 20 from -10 you have to add 30
Repeat that process until you get to the 6th term.
5 (1st term)
5 - 15 = -10 (2nd term)
-10 + 30 = 20 (3rd term)
20 - 15 = 5 (4th term)
5 + 30 = 35 (5th term)
35 - 15 = 20 (6th term)
Since 3 laps are in a mile, if she wants to do 2/3 of that, it will be 2.
Answer:
$138
Step-by-step explanation:
Let the money with Raymond be $y
Let the cost of 1 tshirt be $x
then cost of 8 tshirt = cost of 1 t-shirt*8 = 8x
Raymond wanted to buy 8 t-shirt but he was short of $8.10
It means that 8x is equal to money he had plus $8.10
thus,
y + 8.10 = 8x
y = 8x - 8.10
Next situation
cost of 5 t-shirt = 5x
. instead he bought 5 T-shirt and had $12.60 left,
it means cost of 5 T-shirt plus $12.60 = total money Raymond had
y = 5x + 12.60
comparing y in both the equation
y = 8x - 8.10 and y = 8x - 8.10
5x + 12.60 = 8x - 8.10
=> 8x-5x = 12.60+8.10
=> 3x = 20.70
=> x = 20.70/3 = 6.9
Thus, cost of 1 T-shirt = $6.9
cost of 20 T-shirt = 20*$6.9 = $138 (Answer)
Answer:
Step-by-step explanation:
So we know that Alex is trying to save $230.
He already has forty dollars so we can take forty away from two hundred and thirty. This leaves us with $190 that we need to save.
If he is saving $38 per week. We can divide or estimate and multiply. I prefer to multiply so that is the method I will use right now.
38×5= 190
Therefore, Alex will have enough money to buy a tablet in five weeks.
I hope I am correct and I explained this in a way that you can understand and do it yourself next time.

pi times the radius squared times the height divided by 3, when you know the diameter, you simply divide by two to find the radius, which you then plug into the formula.
