1
Step-by-step explanation:
1 Subtract \frac{1}{3}
3
1
from both sides.
b-\frac{1}{3}=ab−

=a
2 Switch sides.
a=b-\frac{1}{3}a=b−

Answer:
y=1.125x
Step-by-step explanation:
9/8 is the ratio
so, I would do 9/8 which is 1.125. so, one euro is worth 1.125 dollar
y(dollars)=1.125x(euros)
TEST
27 dollars=1.125 • 24
done
Yes, 16.3 is y maybe but or else I need to use a protractor I believe
Answer:
The ratio of perimeter of ABCD to perimeter of WXYZ = 
Step-by-step explanation:
First, we have to determine the multiplicative factor of the dimensions for both figures.
Considering sides AB and WX,
multiplicative factor = 
= 1.5
So that:
XY = 6 x 1.5 = 9
YZ = 7 x 1.5 = 10.5
ZW = 7 x 1.5 = 10.5
Perimeter of ABCD = 6 + 7 + 7 + 8
= 28
Perimeter of WXYZ = 9 + 10.5 + 10.5 + 12
= 42
The ratio of the perimeters of the two quadrilaterals can be determined as;
ratio = 
= 
= 
The ratio of the perimeter of ABCD to perimeter of WXYZ is
.
