Answer:
A
Step-by-step explanation:
Since they have the same slope and have different y-intercept they're parallel
Let
Y be the age of Franco's dad.
X Franco's age
Y = 3*X (1)
(Y +10) = 2*(X+10) +2 (2)
(3*X +10) = 2*X +20 +2
(3-2)X = 22 -10
X = 12 years old (Franco)
Y = 3*12 = 36 years old (Franco's dad)
Mass = density* volume
since density= mass/volume then mass/volume*volume=mass
= 4.5*0.4 = 1.80g
Step-by-step explanation:
Dogs: 12% of 45= 5.4
Cats: 24% of 45= 10.8
Fish: 36% of 45= 16.2
Other: 28% of 45= 12.6
