A)
x = -y -2
y = -x -2
B)
0.5x + y = 1
0.5x + (-x -2) = 1
-0.5x -2 = 1
-0.5x = 3
x = -6
Hmmm well may I ask what your doing with the shapes bc um well if you put them shapes in the circle/oval why is it hard? I don’t do this stuff I’m confused...
So 3x=6+4y
divide both of the equations by 3
x=2+4y÷3
x=2+4/3 y
your answer
x=2+4/3 y hope this will help
Answer:
213
Step-by-step explanation:
convert percent to decimal 48%=0.48
144x0.48= 69.12
estimate 69.12 we got 69
144+69=213
A) Since there are four multiple choice questions Which has one correct answer. The probability of choosing a correct answer is

The probability of choosing wrong answer is

Using the multiplication rule

b) If you guess answers to three of the questions, then the possibilities of getting one correct answer are:
Either the first two are wrong and the third one is correct. This will give the arrangement;

Or the first is wrong the second one is correct and the last one is wrong. This will give the arrangement,

Or the first one is correct and the last two are wrong. This will give the arrangement,

.



c) The probability of getting one correct answer is either the first one is correct or second is correct or third is correct.
