If a is -2 then the denominator would be 0 which is undefined
Ok i hope this is the answer that you are looking for
6*2=12one way
3×4=12second way
12×1=12third way
Sorry if this is not what you are looking for and I couldn't find the fourth way!!
Or incase there is another ways like 6+6=12,9+3=12,12+0=12,24÷2=12
Sorry if I did this wrong
5t = 15.55. Here's why:
Since in the equation 9t = 27.99 is basically multiply two numbers to get a product, divide 27.99 by 9:
27.99/9 = 3.11
3.11 is the value of t. So now that we've found the value of t, plug it into the equation 5t like so:
5*3.11 = 15.55
I hope this helped you out! :)
Answer:
x = -1
y = -2
Step-by-step explanation:
5x + 2y = -9 2y = -9 - 5x y=(-9-5x)/2
3x + 4y = -11
3x+4[(-9-5x)/2] = -11
3x+( -36-20x)/2 = -11
3x-18-10x = -11
-7x = 7
x = -1
y = -2
Answer:
R = 101
S = 131
Step-by-step explanation:
First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.
T=180-128
T=52
You also know that all angles in a triangle equal to 180
Use that to find angle S
180 = R+S+T
180 = 79 + S + 52
180 - 79 - 52 = S
49 = S, exterior S = 180-49 = 131
Exterior R = 180 - 79 = 101
Now add all your exteriors
