-2x + 5 = -1
subtract 5 from both sides: -2x = -6
divide each side by -2: x = 3
plug in 3: 5(3)
multiply: 15
the value of 5x is 15.
To solve problems like this, we must simply break it down and read each part carefully. We can also set it up as a math problem to make it easier to visualize.
The elevator starts on the twentieth floor, so we will represent that with 20.
20
It goes down 11 floors, so we can represent that with a -11.
20-11=9
Now we are on floor 9. Then, we go up 5 floors, so we can represent that with a 5.
9+5=14
Using the math above, we can see the elevator is on the 14th floor.
Answer:
∠ABE and ∠CBD
∠ABC and ∠EBD
Step-by-step explanation:
we know that
<u>Vertical angle</u>s are a pair of opposite and congruent angles formed by intersecting lines
In this problem we have that
∠ABE=∠CBD ------> by vertical angles
∠ABC=∠EBD ------> by vertical angles
therefore
The angles that are vertical angles are
∠ABE and ∠CBD
∠ABC and ∠EBD
Answer: i think its 35
Step-by-step explanation:
Answer:
angle E, the measure is 135
angle J, the measure is 105
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
We are to identify an angle that is supplementary to angle M form the given parallel line.
From the fist diagram, angle E and angle F are supplementary to angle M because they form adjacent angles on a straight line with angle M.
If angle m is 45 degrees, then the value of its supplement is 180-45=135
From the second diagram, angle H,angle J and angle P are supplementary to angle M.
If angle M is 75 degrees, the its supplement is 180-75=105
