Answer:
432 inch square
Step-by-step explanation:
The total material used to make a kite should be equal to the area of the kite. You can find the area of a kite by multiplying the width with length, then divide it by two. The formula will be:
area = length x width /2
area= 18 in * 16 in /2= 144 inch square.
The area of one kite is 144 inch square, then the area for 3 kites will be: 3 * 144 inch square = 432 inch square
All of the above options are true, so the answer is choice D.
Answer:
Step-by-step explanation:
Solution by substitution method
3x-4y=8
and 18x-5y=10
Suppose,
3x-4y=8→(1)
and 18x-5y=10→(2)
Taking equation (1), we have
3x-4y=8
⇒3x=4y+8
⇒x=(
4y+8)/
3 →(3)
Putting x=
(4y+8
)/3 in equation (2), we get
18x-5y=10
18(
(4y+8)
/3) -5y=10
⇒24y+48-5y=10
⇒19y+48=10
⇒19y=10-48
⇒19y= -38
⇒y=-
38
/19
⇒y= -2→(4)
Now, Putting y=-2 in equation (3), we get
x=4y+8
x=
(4(-2)+8)
/3
⇒x=
(-8+8)/
3
⇒x=
0/
3
⇒x=0
∴x=0 and y= -2
