Answer:
x =
Step-by-step explanation:
We have the equation: 3 + =
Move the constant (in this case the constant is 3) to the right side of the equation, changing its sign
=
- 3
Calculate the difference.
=
Divide.
(when dividing two fractions, you can change it to a multiplication problem by switching the numerator and denominator of the divisor.)
So, we get the equation x
which is
.

Answer:
The ratio is .
Step-by-step explanation:
The ratio of the perimeters of Quad ABCD to Quad WXYZ =
But considering sides AB and WX,
representative factor for both figures =
So that;
WX = 12
XY = 1.5 x 6 = 9
YZ = 1.5 x 7 = 10.5
WZ = 1.5 x 7 = 10.5
Thus,
perimeter of Quad ABCD = 6 + 7 + 7 + 8
= 28
perimeter of Quad WXYZ = 9 + 10.5 + 10.5 + 12
= 42
The ratio of the perimeters of Quad ABCD to Quad WXYZ =
=
