Answer:
x=40,y=22
Step-by-step explanation:
62/2=31
31+9=40
31-9=22
40+22=62
So basically it makes a cone
one way to solve is
Vcone=(1/3)hpir^2
r=3
h=2
V=(1/3)(2)pi3^2
V=2pi3
V=6pi
aprox pi=3.141592
V=18.849
round
V=18.8 in^3
The perimeter is 38 , As you can see each of the sides provided also have another side across from it that’s equal to the length, therefore you you double the size of the sides that were given , and add them two together.
Line R
2x + 2y = 18
if we divide by 2 in both side
x + y = 9
Line M
x + y = 9
if x = 1, then y = 8
if x = 2, then y = 7
likewise you can find infinite pair answers for x and y
Answer:
The original price for this dress was $30
Step-by-step explanation:
If 90% of 30 is 27, we have to find out 10% of 30.
How to find it:
1) You make the 10% of 30 into a proportion
10/100=x/30
(Cross multiply)
100x=300
x=3
2) So now since we’ve found 10% of 30, we add it on to 27.
27+3=30
Therefore, the original price of the dress that Kate bought was $30.
