Answer:
This is called system of equations.
Step-by-step explanation:
This combines two equations and then lines them up to a system.
12 is the answer.
The sequence is 12, 6, 3, 3/2
Answer:
x=2
y=1
Step-by-step explanation:
2x+y=5
3x+2y= 8
<=> 6x+3y=15
6x+4y=16
<=> -y=-1
2x+y=5
<=> y=1
2x+1=5
<=> y=1
2x=4
<=> y=1
x=2
Answer: (<em>Draw a circle and a point outside the circle.)</em>
Step-by-step explanation:
Step 1: Draw a circle and a point outside the circle.
Step 2: Draw line OP, to join the center O to point P.
Step 3: Construct the perpendicular bisector of OP.
Step 4: Draw two arcs on the circumference of the circle.
Step 5: Draw tangent lines JP and KP.
Proof:


10x−28=3x+56
10x=3x+56+28
10x=3x+84
10x−3x=84
7x=84

x=12
Hope this helps, have a blessed and wonderful day!
