Assuming this is a system of equations, here is how to find x.
2x + 3y = 45
x + y = 10
Multiply x + y = 10 by 2 so you are able to use the elimination method.
2x + 3y = 45
2x + 2y = 20
Subtract.
y = 25
Now that we've found y, we can plug it in to find x.
x + 25 = 10
Subtract 25 from both sides.
x = -15
Answer:
B
Step-by-step explanation:
The total number of faces on a cube is 6.
The numbers under 3 are 1 and 2.
So numbers 1 and 2 give success.
P(<3) = 2/6
P(<3) = 1/3
The answer is B.
-12 would be it because 2 negatives make a positive so -11+23 is -12
