Opposite sides of a parallelogram are congruent.
3x+ 2= 4x-3
Subtract 3x from both sides
2= x -3
Add 3 to both sides
5= x
2y+7=4y-9
Subtract 2y from both sides
7= 2y -9
Add 9 to both sides
16 = 2y
Divide by 2 on both sides
8 = y
Answer:
Step-by-step explanation:
3x - 95 = -4x + 31
3x + 4x = 31 + 95
7x = 126
x = 126/7
x = 18
If its a right-angled triangle you can find the third side if the length of the other 2 sides are known. Use the Pythagoras theorem.
If you have 2 triangles which are similar and you know the length of one or more sides of one of them then you can find the lengths of corresponding sides in the second triangle.
Solve equation [1] for the variable x [1] x=(3y+6)
Plug this in or variable x in equation [2]
[2] 2(-3y+6)-y= 10
[2] -7y=-2
// solve equation [2] for the variable y
[2] 7y= 2
[2] y=2/7
By now we know this much
X= -3y+6
Y=2/7
Use the y value to solve for x
X=-3(2/7)+6=36/7
(x,y)=(36,7), (2/7)
Answer:
$31.50
Step-by-step explanation:
If you divide $126 by 4, since there is $126 and he wants to divide it <u>equally </u>between his 4 children. If you divide that into a calculator, you'll get $31.5 or $31.50.
