Start the equation by putting the equations equal to each other 3x+14=7x-10
Next +10 on both sides
3x+14=7x-10
+10 +10
You are left with 3x+24=7x
because the 10's canceled each other out.
Next -3x on both sides
3x+24=7x
-3x +3x
You are left with 24= 10x
because like before the 3's canceled each other out
Now you will divide both sides by 10
24=10x

10 10
2.4= X is the answer!
Answer:
C)
Step-by-step explanation:
Answer: Look below
Step-by-step explanation:
1(10x-6y)=-16
3(5x+2y)=66
10x-6y=-16
15x+6y=66
-25x=50
x=-2
Answer:
18
Step-by-step explanation:
54/18=3
72/18=4
90/18=5
Answer:
if its an arc and center angle is given it could be double the size. IF it is a triangle measure you would use Pythagoras for triangle and trig for given angle, if two triangles are shown and they are scale of each other alternative measures given divide into each measure by the correct line and check this with the matching angles. when found as a division this is the ratio so then you just multiply to find the larger measure but divide to find the smaller measure. AC could also be a junction or vector, if its a type of vector then you just follow the arrows and count how many arrows fit the line pick a direction and ie) if its x2 a then you show a+a.
