Answer:
X=4, y=-7
Step-by-step explanation:
To use elimination method, you want to cancel x or y when adding the equations together. So let’s multiply the first equation by -2
2(y)=2(-x-3)
2y=-2x-6
——————
add above equation 2y=-2x-6
to second equation Y=2x-15
add together. 3y=-21
Y=-7
—————————————-
solve for x by substituting y value (7) into either equation
y=-x-3
-7=-x-3
-4=-x
4=x
Answer: Im confused?
Step-by-step explanation:
12.5 minutes becuase 25ft divided by 2 ft is 12.5
The correct answer is letter choice E.
The answer is letter choice E because 4.9 times 10 to the 2nd power which is 490. Then you calculate 6.8 times 10 to the 3rd power which is 6800.
After you calculate these two equations you then add the answer which is 6800+490 which equals (=) 7290.
Letter choice E is the only accurate answer to equal to 7290. How I figured this out is by calculating 7.29 times 10 to the 3rd power the correct answer to this equation is 7290.
It matches equivalently with the problem so the answer is E.
The perimeter of the stop sign would be 88
