4) 7x=x+30. 4) Simplify
5) 7x-x=x+30-x. 5) Subtraction P.O.E
6) 6x=30. 6) subtraction P.O.E
7) 6x/6=30/6. 7) Division P.O.E
8) x=5. 8) Simplify
The area of what? if those are the dimensions of a triangle, you would do base times height divided by 2.
Answer is (-1.5,5)
Midpoint formula is M= ((X1+X2)/2), ((Y1+Y2)/2)
So it becomes ((-4+1)/2), ((9+1)/2)= (-1.5,5)
Answer:
k= -9
Step-by-step explanation:
2k-3=9k+63-3 [expand the 9(k+7) first]
2k-9k=63-3+3 [put the like terms together]
-7k=63 [do the simple math]
k= 63 ÷ by -7
k=-9
Answer:
The missing reason is Subtraction Property of Equality.
Step-by-step explanation:
⇒ (Given)
On Solving we get;
Multiplying 2 on both side we get;

⇒ (Multiplication Property of Equality)
Now Subtracting Both side by 10 we get;

⇒ (Subtraction Property of Equality)
Now Dividing both side by 3 we get;

⇒ (Division Property of Equality)
Hence the missing reason is Subtraction Property of Equality.
