Answer:
your multipling the same number by the same amount of exponents
Answer:
1)4x+4y=1, 6x−y=1
x+y=4, x−y=2
x+y=−2,x+2y=2
2)2x+y=3, 2x−8y=19
Step-by-step explanation:

have a nice day ^_^
The formula for simple interest is: Total amount = Principal ( loan amount) x (1 + interest rate x time (years).
Using the given information you have:
Total = 7540 x (1 + 0.065 x 2.5)
Total = 7540 x (1 + 0.1625)
Total = 7540 x 1.1625
Total = $8,765.25
If you are referring to angles of a line, 102° and 78° could be angles of a line since a line equals 180°. This would also be the same for an interior triangle angle and it's matching exterior triangle angle. The two angles (102° + 78°) would also equal 180° since they would be supplementary angles.
I would need to see a picture to know what you are referring to with the 45°.
Hope this helps a little at least! :)
Answer:
Step-by-step explanation:
This is a geometric mean problem...a ratio. The geometric mean is the height of the triangle, 6. To solve:
and cross multiply to solve for x:
3x = 36 so
x = 12
