Answer:
The number of people vote for blue is 180.
Step-by-step explanation:
Let there are x numbers of total people.
So, of total people vote for blue i.e. people vote for blue.
Now, the remaining number of people are .
If of the remaining people vote for green, then the number of people vote for green will be .
Therefore, finally the remaining number of people is and they vote for red.
Now, {Given}
⇒ x = 288
And the number of people vote for blue is . (Answer)
Answer:
b: < x <
c: x < -5 , x > 7
Step-by-step explanation:
Answer:
I would type these in Math-Way, then select Solve the system of equations (or inequalities, I forget which one). (4, -1, 0) would be the answer.
Here a right angled triangle given. We know that one angle of a right angled triangle is 90°.
As the sum of three angles of a triangle is 180°, so we can say the sum of other two angles of a right angled triangle is (180-90)° = 90°.
Here in the figure the other two angles given and . Sum of these two angles is 90°.
So we can write the equation as,
We have to remove the parenthesis now.
Now we will add the like terms. Here x and 2x are like terms. By adding them we will get,
To solve it for x, now we have to move 15 to the other side by subtracting it from both sides.
Now to get x, we have to move 3 to the other side, by dividing it to both sides.
We have got the required value of x.
The solution is x= 25.
