<h3>Answer: x < -2, choice B</h3>
===========================================
Work Shown:
10x + 18 < -2
10x + 18-18 < -2-18 ... subtract 18 from both sides
10x < -20
10x/10 < -20/10 ... divide both sides by 10
x < -2
Answer:F B G E A
Step-by-step explanation:
1. F( a rigid transformation only changes the position but the size and angles remain the same)
2. B(The angle of rotation symmetry is the smallest angle the figure can be rotated to coincide with itself.)
3. G(Congruent means that it is the same size and shape)
4. E(Translation moves the whole shape including the points so that the shape and sizes remain the same)
5. A(Though it's position may change, reflective symmetry ensures that no other parts of the shape can change no matter what.)

Answer:
Mode-10
Mean-12
Range-13
Step-by-step explanation:
Mode is the most common which is 10
Mean is the averge so you add them all together then diviede based on how many numbers there are
Range is the difference between the smallest and biggest number so you just subtract. Biggest- smallest
Anw:
a
Step-by-step explanation:
72*4=5x
=288
5x=288
x=288/5
=57.6
x=57.6
57.6/72=0.8
4/5=0.8
Answer:
The second one
Step-by-step explanation:
x+6=2x (picture shows)
x=6 (algebra)
3x+1=19
2x+7=19
PQ=QR
SQ=SQ
