The ratio of dark chocolate candies to white chocolate candies is 3 to 2. There are 18 pieces of dark chocolate. How many pieces of white chocolate are there?
1 answer:
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.

<em>x₁ = 3</em>
<em>x₂ = - 12</em>
Step-by-step explanation: <em>Hi there ! </em>
<em>| 2x + 9 | = 15</em>
<em>1.</em>
<em>2x + 9 = 15</em>
<em>2x = 15 - 9</em>
<em>2x = 6</em>
<em>x = 6 : 2</em>
<em>x₁ = 3 </em>
<em>2.</em>
<em>2x + 9 = - 15</em>
<em>2x = - 15 - 9</em>
<em>2x = - 24</em>
<em>x = - 24 : 2</em>
<em>x₂ = - 12 </em>

Answer:
(1,8)
Step-by-step explanation:
Answer:
1. (4x-10)/2
4x/2 - 10/2
2x - 5
2. (1-50x)/-2
1/-2 -50x/-2
25x - 1/2
3. 5(x + 10)/25
(5x + 50)/25
5x/25 + 50/25
1/5 x + 2
4.(-0.2x + 5)/2
-0.2x/2 + 5/2
-0.1x + 2.5
90 hazelnuts = 125g
Therefore, the mass of one hazelnut is this...
90 / 90 = 125 / 90
1 hazelnut = 25/18 grams
630 calories = 100 grams
100 divided by 25/18 = 72
Therefore...
630 / 72 = 1 hazelnut
AND THE ANSWER IS
8.75 calories = 1 hazelnut
