The number of penguins is 15.
The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The ratio of dolphins to penguins = 2:5
This means,
For every 2 dolphins, there are 5 penguins.
Now,
For 6 dolphins,
2 dolphins = 5 penguins
Multiply 3 on both sides.
6 dolphins = 15 penguins
Thus,
There will be 15 penguins.

Answer: You divide both sides by -3.
Step-by-step explanation:
We're asked to solve the equation: .
To do this, divide both sides by -3:
Simplify
Therefore, that's our answer.
Answer:
divide both sides by - 3
Step-by-step explanation:
given the equation
- 3y = 2x - 7
to isolate y then divide both sides by - 3
y = , that is
y =
or
y = x + = - x +
Answer: Hello mate!
Ok, the 6 sides cubes can be thinked as two normal dice.
A fair game is that game where both players have the same chance to win, first, let's calculate the situations where you friend win:
this are, if the cubes have numers between 1 and 6:
1 + 6
6 + 1
2 + 5
5 + 2
3 + 4
4 + 3
where 1 + 6 is different to 6 + 1 because in the first one you rolled a 1 and your friend a 6, and in the second one you rolled a 6 and your friend a 1, so are different events.
Then you can see that you friend has 6 combinations where he wins.
So we need to find two numbers that between them, have the same number of combinations.
I can think, for example in 4 and 10:
the combinations for 4 are:
2 + 2
3 + 1
1 + 3
a total of 3 combinations:
for 10 are:
5 + 5
4 + 6
6+ 4
also 3 combinations.
So if you win a point if the sum is 4 or 10, you also have 6 combinations where you win, then the game is fair
Now, suppose the first number is 5, let's find the second:
the combinatios for 5 are:
4 + 1
1+ 4
2 + 3
3 + 2
a total of 4 combinations, this means that we need to find another number that only has two combinations, wich can be, for example, 3
the combinations for 3 are:
1 + 2
2 + 1
2 combinations, then if your numbers are 3 and 5, you have 6 combinations where you win, and the game is fair.

Answer:
(1,2) and (2,2) since blue is a solid line
Step-by-step explanation:
To prove if a point satisfies the inequalities,find the point in the point that both inequalities overlap. In the picture, this is colored purple (both pink and blue/purple).
Answer:
(1,2) and (2,2) makes true
Step-by-step explanation:
y < 5x + 2
y >=1/2(x) + 1
(–3, 2)
Plug in the ordered pair (x,y) in each inequality
2 < 5(-3) + 2 -----> false
(–1, 3)
3< 5(-1) + 2 --------> false
(0, 2)
2 < 5(0) + 2 -------> false
(1, 2)
2 < 5(1) + 2 ---------> True
2 >=(1/2)1 + 1 ----------->True
(2, –1)
-1 < 5(2) + 2 ---------> True
-1>= (1/2)(2) + 1 -----------> false
(2, 2)
2 < 5(2) + 2 ---------> True
2>= (1/2)(2) + 1 -----------> True
