Answer:
y= 4
Step-by-step explanation:
Okay so this is inverse operations.
You have to move the 2y over underneath the 6y and subtract them, you should get 4y. Your problem should now look like this. 4y-20=-4
Now you need to more the +20 over underneath the -4 and add them. Your problem should now look like this. 4y= 16
You now divide 4 into 16 which will give you 4
So y= 4
Have a good day!
THIS IS EASY. I don't have a calculator on me so bare with me.
1.) 7x - 9 = -4x + 90
7x +9. = -4x. + 9
7x. = -4x. 99
+4x = +4x. + 99
11× = 99
÷ 11. ÷ 11
X = 9
U can solve the rest. Are you serious?
Answer:
1. area = 1/2bh = (1/2)(21)(18) = 189 yd²
2. 3x2x3x2 = 36 different ways
3. area of kite = (1/2)(18)(24) = 216 units²
4. 8:52 or reduced, 2:13
