Step-by-step explanation:
<u>We need to add up 4 angles to get 360.</u>
<u>Here is what you fill out for the missing boxes:</u>
- 70 + 70 = 130
- 70 goes into the smallest angle.
- 115 + 115 = 230.
- If we do 120 or 130, It would make 370 or 390.
- 130 + 230 = 360.
- 50 + 50 = 100.
- Missing 50 goes into smallest angle.
- 130 + 130 = 260.
- 260 + 100 = 360.
Answer: D
Step-by-step explanation:
Given that Svana wants to solve the equation 1/2x - 1.0675 = 3x - 4145.
This equation is a system of equations which can be solved by using simultaneous equation methods.
But if she uses a graphing program to graph the equations y = 1/2x - 1.0675 and y = 3x - 4.145
The solution of 1/2x - 1.0675 = 3x - 4.145. Will be the point of intersection of the two equation.
Trace the point of intersection to the x - axis and also to the y - axis.
The solution to the system of equations is ( 1.231, - 0.452 )

Answer:
Use the order of operations in reverse and remember that dividing or multiplying by a negative reverses the inequality
Explanation:
The order of operations is PEMDAS in reverse it is PESADM ( if you lose your cell phone in PE you are a SAD M(am)
Remember multiply or dividing by a negative reverses the value of the quality being divided or multiplied.
Just do the order of operations in reverse as in solving an equation always doing the opposite. Then remember to reverse the inequality sign whenever the inequality is multiplied or divided by a negative.
