Step-by-step explanation:
28 + 19 + 13 equal 60%
therefore 40% divided by 60% multiply by 160 gives number of chicks
63.24 is equivalent to 63.240.
solution is (4, - 7 )
given the equations
y = 2x - 15 → (1)
4x + 3y = - 5 → (2)
substitute y = 2x - 15 into (2)
4x + 3(2x - 15) = - 5
4x + 6x - 45 = - 5
10x - 45 = - 5 ( add 45 to both sides )
10x = 40 ( divide both sides by 10 )
x = 4
substitute x = 4 into (1) for corresponding value of y
y = (2 × 4 ) - 15 = 8 - 15 = - 7
solution is (4, - 7 )
32 homes. divide 96 by 3 because the 96 homes each took 3 kittens
