Answer:
There are <u>12 marbles</u> in Daniel's set.
Step-by-step explanation:
Given:
Daniel has a set off green,blue and red.
The red marbles make up exactly half of the set.
The set has 2 blue marbles.
The green marbles in set are as twice of the blue marbles in set.
Now, to find the number of marbles in Daniel's set.
Let the number of marbles in Daniel set be
So, the red marbles =
Blue marbles = 2.
And the green marbles =
According to question:
<em>Multiplying both sides by 2 we get:</em>
<em /><em />
<em>Subtracting both sides by </em><em> we get:</em>
Therefore, there are 12 marbles in Daniel's set.
Answer:
The equivalent ratios are:
s = \frac{LA}{r}s=
r
LA
r = \frac{LA}{s}r=
s
LA
The formula LA = rsLA=rs is given
In order to determine the equivalent ratios, make r the subject of the formula and s the subject of the formula in the above equation
To make s, the subject of the equation, divide both sides of the equation by r
s = \frac{LA}{r}s=
r
LA
To make r, the subject of the equation, divide both sides of the equation by s
r = \frac{LA}{s}r=
s
LA
