Answer:
4x + 31 = 154
9x + 31 = 154
Step-by-step explanation:
$154 total
31 candles
4x + 31 = 154 <-- this is to find out how many small candles can be bought
9x + 31 = 154 <-- this is to find out how many large candles can be bought
I'm pretty sure these equations work! :)
After that its just simple math!! :)
I think it is 72.2 percent because 9x5=45k and 45k-32.5k= 12.5k so 32.5 percent of 45 is 72.2 (rounded to the nearest tenth) btw I feel lonely
Answer:
Step-by-step explanation:
Volume of a cylinder is given by the function
where v is volume, r is radius and h is height.
In order to find the radius we just divide the diameter in half and get
now we just plug the values in the formula
They relate to each other because you have to find the Base and Height
<span>ABCD is an isosceles trapezoid with legs AB and CD
∴ AB = CD
</span>
<span>AB = 6y +5
</span>
<span>CD= 2y +1
∴ 6y + 5 = 2y + 1
6y - 2y = 5 - 1
4y = 4
∴ y = 4/4 = 1
