You multiply 31 by 100 because one meter equals 100 centimeters. Then that gives you 3100 which is what 31m equals to in cm.
4n-2n+4=-1+17
2n+4=-1+17
-1+17=16
2n+4=16
Move + 4 to the other side. Sign changes from +4 to -4
2n+4-4=16-4
2n=12
Divide by 2 for 2n and 12
2n/2=12/2
n=6
Check answer by using substitution method
4(6)-2(6)+4=16
24-12+4=16
12+4=16
16=16
Answer : n=6
Step-by-step explanation:
area of first triangle =1/2×112×202×sin30°
area of second circle=1/2×202×197×sin60.5°
- 1/2×202×197×0.870
- 17310.39m²
Total area of estates=area of first triangle +area of second triangle
hope it helps.
The answer is false!
-5 x 0 = 0 0 + -2 = -2 So the first statement is true.
3 x 0 = 0 5 x -2 = -10 Not -12, so this statement is false.
Since the ordered pairs only work for 1 equation, they are not a solution!
