Answer:
x=-6 y=7
Step-by-step explanation:
8x+5y=-13; x+y=1
Isolate x and substitute
(-13-5y)/8 +y=1
Isolate y
y=7
substitute y=7
(-13-5*7)/8=-6
Mean: [45+65+30+50+20+30]/6 = 40.2
Median
First order the number {20, 30, 30,45, 50, 50}
The median is the average of the two values in the middle of the list: (30+45)/2 = 37.5
Mode: 30 and 50 (they are repeated the same number of times)
Answer:
C. <w and <y
Step-by-step explanation:
<t and <x are corresponding angles, therefore they are congruent to each other by the corresponding angles theorem.
<w and <y are also corresponding angles and are therefore also congruent.
<x and <z are congruent also based on the vertical angles theorem.
<t and <z are alternate exterior angle, and are therefore congruent also.
So, from the pairs of angles given as options, the only given pair of angles that are congruent would be:
<w and <y
Answer:
x> 5
Step-by-step explanation:
x - 8 > -3
Add 8 to each side
x - 8+8 > -3+8
x> 5
