Answer:
x = -5 y = -3
Step-by-step explanation:
-3x + 2y = 9
multiply the 2nd equation by 3 to set it up for elimination
3(x - 3y)= 3(4)
3x-9y = 12
so now combine both to add
-3x + 2y = 9
3x - 9y = 12
Adding both gives you
-7y = 21
divide both by -7 and you get
y = -3
and you substitute y back into equation to get x
x - 3 (-3) = 4 gives you
x + 9 = 4
x = 4 - 9
x = -5
The answer is 66% because you divide 5.28 divided by 8
You have x , x+7, and 7x-7. When you add those up and equal it to 180 you can get your x. X equals 20
So one angle is 20 degrees
The second angle is 27 degrees
And the third angle is 133 degrees.
Answer:
A. tossing five coins
C. spinning a spinner with 2 equal parts 5 times
Step-by-step explanation:
There are two equally likely outcomes for each kitten's gender: male or female.
A coin has two equally likely outcomes: heads or tails. So tossing five coins can be used to simulate the probability.
A spinner with two equal parts also has two equally likely outcomes. So spinning a spinner with two equal parts five times could also be used to simulate the probability.
