Answer:
Student 2 used the correct steps to construct parallelogram PQRS.
Step-by-step explanation:
Out of all the students, student 2 got all the steps correct.
Fix the compass at Q and draw an arc that intersects side QP.
Without changing the width of the compass, move the compass to R and draw an arc.
Draw a line segment from R that passes through T and intersects the second arc at S.
Step-by-step explanation:
problem 1.
1. 6y = 30
2. y = 5
3. 3x + 2(5) = 16
4. 3x+10=16
5. 3x=6
6. x=2
solution: (2,5)
problem 2.
1. x=7
2. 4(2)-2y=18
3. 28-2y=18
4. -2y= -10
5. y=5
solution (7,5)
problem 3
10x=10
x=1
7(1) +y =-2
y=-9
(1,9)
problem 4
0= -6
no solution
problem 5
0=0
Infinite many
Answer:
<2 and <7
Step-by-step explanation:
Because <2 and <6 are equal and <3 and <7 are equal as well means that angles <2 and <7 are alternate exterior angles as well as angles <3 and <6.
Answer:
B. 30°
Step-by-step explanation:
By remote interior angle theorem:
100° = x + 70°
100° - 70° = x
30° = x
x = 30°
