Sin(theta) = 4/5,

We will switch it to formula:
Answer:
a
Step-by-step explanation:
x+2y=-10
-x -x
2y=-10-x
y=(1/2)x-5
This is one of the lines and reduces the options to a or c.
3x-y=12
-3x -3x
-y=12-3x
y=3x-12
This is the line with the positive slope and since both lines match, the answer is a.
X = 3y - 6 so:
2(3y - 6) - 4y = 8
6y - 12 - 4y = 8
2y - 12 = 8
2y = 20
y = 10
x = 3(10) - 6
x = 30 - 6
x = 24
Answer:
15 have no flowers, 6 have pink flowers, and 9 have red flowers.
Step-by-step explanation:
If we add the percentages we get 50%. That means half of the plants (15 of the 30) have no flowers.
Since we have taken away half of the plants, we have to double the percentages. So 20% becomes 40% and 30% becomes 60%.
So now we get 40% of 15, which is 6, and 60% of 15, which is 9.
Another way of doing the last step is just subtracting the 6 from the 15 to get the 9.
Answer:
x is greater than or equal to 33.
Step-by-step explanation:
Solve it like a normal equation for x. Add 24 to both sides to isolate x. positive 24 and negative 24 cancel each other out. 24 plus 9 is 33. Therefore, x is greater than or equal to 33. Hope this helps!
