Answer:
All the angles on the bottom line are 60. The angles on the top line from left to right is 130, 60, 60, 130.
Step-by-step explanation:

Answer:
The sum of all the possible values for z that satisfy the above equation is -5.
Step-by-step explanation:
The given equation is
We need to find the sum of all the possible values for z that satisfy the above equation.
The given equation can be rewritten as
Cancel out common factors.
Add 2 on both sides.
Multiply both sides by -1.
Only z=-5 satisfy the given equation.
Therefore the sum of all the possible values for z that satisfy the above equation is -5.
The correct question is
<span>Brett made a scale drawing of a rectangular room in his house. The actual length of the room is 12 4/5 ft. The scale used to make the drawing was 1/4 in.=1 ft. What is the length, in inches, of the room on the drawing?</span>
we know that
scale=measure in the drawing/measure in the actual
measure in the drawing=measure in the actual*scale
in this problem
scale=1/4 in/ 1 ft-----> 1/4
measure in the actual=12 4/5 ft-----> (12*5+4)/5----> 64/5 ft
so
measure in the drawing=(64/5)*(1/4)----> 3.2 in
the answer is
the length, in inches, of the room on the drawing is 3.2
Answer:
B 6,17
Step-by-step explanation: If you plug in the value of x from each of the choices only b gives the correct value of y. If you put 6 in the place of x in y= 3x-1 then y= 18-1 which is 17, and it does say 17 in 6,17.
