These marks are used in geometry to symbolize congruence. If two sides or two angles are congruent, they are assigned with the same symbol.
A. Side AD is congruent to Side CB
B. Side HE is congruent to side HG. Side EF is congruent to Side GF.
C. The base angles are congruent.
D. Side QF is congruent to Side MN, and Side QM is congruent to Side PN. The shape is a rectangle.
The colors on the image should match the correct blank spots on the proof. Please let me know if you disagree or is confused by my choices.
Substitution:
2x + (6(1/2x - 6)) = 19
2x + 3x - 36 = 19
5x - 36 = 19
+ 36
5x = 55
÷ 5
x = 11
y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5
Elimination:
y = 1/2x - 6
- y
0 = 1/2x - 6 - y
+ 6
1/2x - y = 6
3x - 6y = 36
2x + 6y = 19
(add)
5x = 55
÷ 5
x = 11
y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5
I hope this helps! Let me know if you need me to explain why I did some things :)
In rounding, a number must be 5 or more to round up, and 4 or less to round down.
To round up to 4.26 you would need a number between 4.255 and 4.264
4.258 and 4.261 are two examples
