12% of 1200 is 144, so subtract that. you get 1056. 12% of that is 126.72, so you subtract that. you get 929.28. 12% of that is 111.5136 and you subtract that. and so on and so forth. the answer would be 557.
Answer:
z = 3
Step-by-step explanation:
Similar polygons have the ratio of their corresponding sides equal to each other. There:
9/z = 6/2
Cross multiply
z*6 = 9*2
6z = 18
z = 18/6
z = 3
The y-intercept is 60
the slope is 30
the equation of the line is y=30x+60
the ordered pair (4,120) represents and increase of 30 minutes per hour
You divide 2220 by 555 and you get 4 hours.
Answer:
x=1, y=-1. (1, -1).
Step-by-step explanation:
2x+3y=-1
3x+5y=-2
-----------------
3(2x+3y)=3(-1)
-2(3x+5y)=-2(-2)
-------------------------
6x+9y=-3
-6x-10y=4
--------------
-y=1
y=-1
2x+3(-1)=-1
2x-3=-1
2x=-1+3
2x=2
x=2/2
x=1
