Answer:
(-1,3)
Step-by-step explanation:
–2x – 9y=-25
-4x – 9y=-23
Multiply the second equation by -1
4x + 9y=23
Add this to the first equation
–2x – 9y=-25
4x + 9y= 23
-----------------------
2x = -2
Divide each side by 2
2x/2 = -2/2
x = -1
Now we need to find y
4x+9y = 23
4(-1) +9y = 23
-4 +9y = 23
Add 4 to each sdie
-4+4 +9y = 23+4
9y = 27
Divide each side by 9
9y/9 = 27/9
y =3
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
1. 326.73 Its easy, just get the circumference of the circle and multiply it by 9. Then get the area of the circle and multiply that by 2, then add the values together. Cant do 2 or 3 cause I feel like I will get them wrong since I start overthinking it.
