there are 18 pieces of dark chocolate and the ratio of dark and white is 3:2 so we can divide 18 by 3.
18/3 = 6.
This means the ratio of dark chocolate to white as a 1:1 ratio would be 6:6 so we can multiply 6 by 2 to give us the total amount of pieces of white chocolate.
6*2 = 12.
Therefore there are 12 white chocolate pieces.
4.) (the next prime function)
2x2x3x2
2x2x3x2x2
2x2x3x2x2x2
-2 + 4x - 4
= 4x-6
Make sure to distribute everything and then combine like terms.
Answer: 4x-6
Answer: x = 9
Step-by-step explanation: divide 2/3x by 2 and do that to both sides to get 1/3x = 3 then multiply by 3 to get the whole x. multiply on both sides to get x = 9.
Step-by-step explanation:
let both unknowns be x and y
x = 5y. ......(1)
x + y = 90. ......(2)
sub eqn (1) into eqn (2)
5y + y = 90
6y = 90
y = 90/6
= 15
sub y = 15 to eqn (1)
x = 5y
x = 5 × 15
× = 75
