Answer:

Step-by-step explanation:
The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.

We can add up that and the other arcs to 360.





Plug in 2 for WX.

Answer: The answers are in the steps.
Step-by-step explanation:
A) 4
= 9/2 * 13 = 117/2
B ) 13 ( 58 + 1/2)
= 754 + 6.5
= 760.5
Allen's work is not written properly so I have rearranged it as shown below:
Original problem) –8.3 + 9.2 – 4.4 + 3.7.
Step 1) −8.3 + 9.2 + 4.4 + 3.7 Additive inverse
Step 2) −8.3 + 4.4 + 9.2 + 3.7 Commutative property
Step 3) −8.3 + (4.4 + 9.2 + 3.7) Associative property
Step 4) −8.3 + 17.3
We can see that in step 1), Allen changed -4.4 into +4.4 using additive inverse. Notice that we are simplifying not eliminating -4.4 as we do in solving some equation. Hence using additive inverse is the wrong step.
Alen should have collect negative numbers together and positive numbers together.
Add the respective numbers then proceed to get the answer.
–8.3 + 9.2 – 4.4 + 3.7
= –8.3 – 4.4 + 9.2 + 3.7
= -12.7 + 12.9
= 0.2
Answer:
(24, -15)
Step-by-step explanation:
-3x + 4y = 12
3x – 6y = 18
Add the two equations together to first solve for y
-2y=30
y=-15
Enter -15 into one of the equations to solve for x
-3x + 4(-15) = 12
-3x-60=12
-3x=72
x=24
