Apeacock weighs 4,250 g. the mass of a magpie is 1/25 the mass of the peacock. if the mass of the parrot is 12 times the mass of the magpie, what is the total mass of the three birds?

6460g

Explanation:

Peacock = 4250g

Magpie = 1/25 x 4250 = 170g

Parrot = 12 x 170 = 2040g

Total = 4250 + 170 + 2040 = 6460g

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

homozygous. one is homozygous, while two is heterozygous.
