Use the triangle angle theorem:
All interior angles of a triangle equal 180 degrees.
If you use the theorem you should get the first one 19,70,91
Answer:
(E) 22,400
Step-by-step explanation:
Let b represent the amount invested in bonds. Then b/4 is the amount invested in stocks, and the total amount invested is ...
b/4 +b = 28000
5/4b = 28000 . . . . . collect terms
b = (4/5)(28000) = 22,400 . . . . . multiply by 4/5
22,400 is invested in bonds.
Answer:
8/3
Step-by-step explanation:
Answer:
x = -7, y = -9
Step-by-step explanation:
The coefficient (the number before) the y is the same but the signs are opposite so add the equations together:
x-3x+y-y=-16+30
-2x=14
x=-7
y=-16-x=-16--7=-9
Answer:
Soo the triangle adds up to 180 so u know the right angle is 90 so add 15 and 14 and 90 and minus it by 180.
I THINK!!!! I SO PLEASE CHECK THIS BEFORE YOU DO IT
