Answer:
x=17/5
Step-by-step explanation:
2 1/5=11/5
5 3/5=28/5
------------------
x+11/5=28/5
x=28/5-11/5
x=17/5
An ant on the ground is 22 feet from the foot of a tree. She looks up at a bird at the top of the tree, and her line of sight makes 30 degrees with the ground. How far is she from the top of the tree? (Hint: Find x.)
33.6 feet
Answer:
A) x = -8
B) x = 3
Step-by-step explanation:
This quadratic is already factored so all we have to do is solve for the zeroes. We can separate the two factors of the quadratic into x-3=0 and x+8=0. Solve for x in both of the equations and we get the zeroes as x = 3 and x = -8.
3x+20=100
Now you would need to move the constant to the right side and change within it’s sign
3x=100-20
Now you would subtract the numbers so for 100-20 would give you 80
So now you then do 3x=80
But if you want to divide the equation, divide it by both sides by 3
Which would give you x=80/3, x=26.6 or x=26 2/3
