Answer:
The answer to your question is x = 30; y = 14
Step-by-step explanation:
Data
JK = x PR = 20
JL = 21 PQ = y
LK = 18 QR = 12
Process
1.- Find x
Use proportions to find it
JK/PR = LK/QR
Substitution
x/20 = 18/12
Solve for x
x = 20(18/12)
x = 360/12
x = 30
2.- Find y
PQ/JL = PR/JK
Substitution
y/21 = 20/30
Solve for y
y = 21(20/30)
y = 420/30
y = 14
6.3 = 0.9y
y would equal 7
1.) Convert the measurements of Naomi's pets so that the two has the same unit of measurements. I will use cm.
1 mm = .01 cm;
Therefore: 40 mm = 4 cm is the length of the fish
2.) Subtract the pets' measurements:
25 cm - 4 cm = 21 cm
3.) Therefore, Naomi's guinea pig is 21 cm longer than her fish.
