Answer:
no solutions
Step-by-step explanation:
10x+2y=42
5x+y=20
Multiply the second equation by -2 to use elimination
-2(5x+y)=20*-2
-10x -2y = -40
Add this to the first equation
--------------------------
0 = 2
This is never true. This means there are no solutions
Answer: 15•5= 75
so make an equation. You now that RS=6n and RS=42. ST is the total sum of all points so the equation would be 6(42)=35. 6X42= 252. Divide 252 by 35 and your answer should be A: 7
The equations
and
are really the same, we're just setting , or .
So we get
look at the angles. they all ad up to 180 degrees devide that by 9, and there you go!
y=9
