Answer:
B
Step-by-step explanation:
-1+4=3
Answer:
3x+2=3x-2
Step-by-step explanation:
The second equation has no solution, because is not true
so
3x+2=3x-2 ------> is not true
therefore
The equation has no solutions
Answer:
5,9,2
Step-by-step explanation:
Answer:
x = 133
Step-by-step explanation:
First, determine what total sum would be needed for the mean to be 114. Do this by multiplying 114 by 6 (bc total number of values in data set includes the variable <em>x</em>).
114 x 6 = 684
Next, add the five known values to get a sum of 551.
Now, just: 684 - 551 = 133
For the mean to be 114, x must equal 133.
Answer:
the answer is triangles ABC and DEC are similar
Step-by-step explanation:
angle C is a common angle for both triangles
angle D is equal to angle A ( corresponding angles)since they are parallel
angle B is also equal to angle B for the same reason as angle D and A
since the three angles of the two angles are equal they are similar
