Answer:
12-x
Step-by-step explanation:
Answer:
seconds
Step-by-step explanation:
When the ball hits the ground, its height will obviously be 0. Therefore, you can set up the equation the following way:
Plugging this into the quadratic equation, you get:
Since the time must be positive, it takes the ball seconds to hit the ground, or around 3.828. Hope this helps!
22 because you take the smallest and largest number and subtract them so you do 81-59=22
Complementary angles add up to 90 degrees.
Which means.. the equation is
8x-23+7x-7=90
Combine like terms you should get
15x-30=90
Add 30 on both sides
15x=120
Divide 15 x=8
Plug in 8 to (8x-23)
8(8)=64-23=41

This is what I learned:
D = Divide
M = Multiply
S = Subtract
B = Bring down
C= Check
D= Dad
M= Mom
S= Sister
B= Brother
C= Cousin
Hope this helped you! :)
