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.
Gained in total = 10.
Moved Backwards in total = 3.
But if you keep them all together with the amount taken away, they've only gained 8 yards.

this is what I would come up with because.
y=the number of people infected
x=the number of days that have passed
Answer:
D
Step-by-step explanation:
The augmented matrix for the system of three equaitons is

Multiply the first row by 5, the second row by -3 and add these two rows:

Subtract the third row from the second:

Divide the third row by 6:

Now multiply the third equation by 26 and add it to the second row:

You get the system of three equations:

From the third equation

Substitute z=2 into the second equation:

Now substitute z=2 and y=5 into the first equation:

The solution is (1,5,2)
