Answer:
x = 35.4
Step-by-step explanation:
Sum of all interior angles in a triangle = 180°
Therefore:
(x + 2)° + (2x + 2)° + (2x - 1)° = 180°
x + 2 + 2x + 2 + 2x - 1 = 180
Collect like terms
x + 2x + 2x + 2 + 2 - 1 = 180
5x + 3 = 180
Subtract 3 from each side
5x + 3 - 3 = 180 - 3
5x = 177
Divide both sides by 5
5x/5 = 177/5
x = 35.4
Answer:
4.468275*(10)^(11)
Step-by-step explanation:
Difference is 94400000-9290000=85110000 miles. This distance in feet is 4.468275*(10)^(11)
Since the left side of the equation says f(5), then plug in 5 for x.
So, it is:
-4|5| + 3
= -20 + 3
= 23
Answer:
C) -3x=-3
Step-by-step explanation:
When you subtract the 3x-y=7 from 6x-y=10, you will receive the following equation:
3x-6x-y-(-y)=7-10
-3x-y+y=-3
-3x=-3
As we can see, this equation matches the one in option C, meaning that it's our answer!
Answer:
Step-by-step explanation:
Note that because BD is an angle bisector, then angle XBD and angle DXY are equal. Also note that BYD and BXD are equal because they are both right angles. Also, by the transaitive property, BD = BD. Therefore, it can be concluded that BXD is congruent to BYD.
Therefore, we must solve 
.
