For this case we have the following system of equations:
We multiply the first equation by -5:
Thus, we have the equivalent system:
We add the equations:
We find the value of the variable "x":
Thus, the solution of the system is:
Answer:
Answer:
<AXC = 101 degrees.
Step-by-step explanation:
The question says that XB is a bisector which means that <AXB = 1/2 of AXC
You can't do the question if that assumption isn't true.
<AXC = 8x - 7
<AXB = 3x + 10
3x + 10 = 1/2 ( 8x - 7) Multiply both sides by 2
2(3x + 10) = 8x - 7 Remove the brackets
6x + 20 = 8x - 7 Add 7 to both sides
6x + 20 + 7 = 8x Combine
6x + 27 = 8x Subtract 6x from both sides
27 = 8x - 6x Combine
27 = 2x Switch
2x = 27 Divide by 2
x = 27/2
x = 13.5
AXC = 8x - 7
AXC = 8*13.5 - 7
AXC = 108 -7
AXC = 101
The population after 8 min is 1200 sorry that's only one I got time for. I think it should right though.
Answer:
∠ XMZ = 74°
Step-by-step explanation:
Since the corresponding arcs on the 2 circles are congruent , then the central angles are congruent, that is
6x - 88 = 3x - 7 ( subtract 3x from both sides )
3x - 88 = - 7 ( add 88 to both sides )
3x = 81 ( divide both sides by 3 )
x = 27
Then
∠ XMZ = 3x - 7 = 3(27) - 7 = 81 - 7 = 74°
Answer:
This is all right!
Step-by-step explanation:
This is all correct! But for questions like 25 and 26 try to write the name of what is heaviest. "The onion is the heaviest", don't just write the number. Same goes for 27, write the names. Other than that good job!!
Hope this helps!!
