-(-2x-6y=-16)
2x+6y=16
4x-6y=-58
Y's cancel out, then add the rest
6x=-42
divide both sides by six
x=-7
plug x into any previous equation
2(-7)+6y=16
-14+6y=16
6y=30
y=5
Answer:
Angle 6 is 42 degrees
Angle Q is 56 degrees
Angle is 74 degrees
Let me know if this helps :)
2x2 for each pen with four in a square and one to the side kind of like this
=== ==
each length of fencing would be 2 meters and the total square footage would be 20 meters because some of the fencing is used for more than one pig's pen
the dimensions would be hard to show, but 4x4+ a 2x2
If you're using log:
Swap both sides: 1100 · 1.7^n = 7000
Divide both sides by 1100: 1.7^n = 70/11
Concert decimal to a fraction: (17/10)^n = 70/10
Take the log of both sides. (Put 17/10 into the subscript of log like the picture shows)
The answer is the decimal.
