To solve for the longest side, the hypotenuse, you have to use the pythagorean theorem. It will be 10^2 + 9^2 = c^2. 100 + 81 =c^2.
c^2 = 181 so c = sqrt(181).
to find sin of A do opposite/hypotenuse which gives you 9/sqrt(181)
to find cos of A do adjacent/hypotenuse which gives you 10/sqrt(181)
15-b=4b-5(5-3)
Multiply the bracket by -5
(-5)(5)=-25
(-5)(-3)=15
15-b=4b-25+15
15-b=4b-10
Move 15 to the other side
Sign changes from +15 to -15
15-15-b=4b-10-15
-b=4b-25
Move 4b to the other side.
-b-4b=4b-4b-25
-b-4b=-25
-5b=-25
divide both sides by -5
-5b/-5=-25/-5
Answer: b=5
The
first graph.
The equation is x - 1

In order to solve it, you need to get x by itself.
Add 1 to both sides. 3+1=4
x

Since this is your sign

the arrow has to point towards the left, and the circle needs to be colored in.

Answer:
16/15 or 1 1/15
Step-by-step explanation:
Subsitute p for 4/5
4/5+4/15
make common denominators
12/15+4/15
=16/15
