Answer:
18
Step-by-step explanation:
1/3 = 18 we are givien the number of kids in one section so if each section will have an equal amount of kids each section will have 18 kids.
5sinx-4 =2sinx-4
5sinx-2sinx= 4-4
3sinx=0
sinx=(0÷3)
sinx = 0
x = sin^-1 (0)
x= 0 degrees
And also x = (180- 0 ) = 180 degrees
so x; has 2 answers within the above given interval.
They are;
x= 0 degrees and x=180 degrees
Answer:
13
Step-by-step explanation:
All the lengths in triangle ADE are twice those in similar triangle ABC. So ...
x-1 = 2(6)
x = 13
Answer:
The answer is (x + 5)(x - 5).
Step-by-step explanation:
Assuming that 25 is a perfect square so you can apply :
Test :
Answer:
x = 2 and y = -2
Step-by-step explanation:
We must first eliminate the y-variable:
2x + 3y = -2
3x - 6y = 18
4x + 6y = -4
3x - 6y = 18
_________
7x = 14
x = 2
Since we know x=2, we plug that back into one of the original equations to find y:
2x + 3y = -2
2(2) + 3y = -2
4 + 3y = -2
3y = -6
y = -2
Therefore, x = 2 and y = -2
