Answer:
x 2 y -4
Step-by-step explanation:
13x = -54 -20y give it is A
-10x = 60 + 20y give it is B
A + B the sum of the left side of equation is equal to the sum of the right side of equation
13 + (-10x) = -54 -20y + 60 + 20y
3x = 60-54
3x = 6
x=2
so put the x value in A or B equation you can receive y value (B is easier)
y = -4
Answer:
210.
Step-by-step explanation:
Combination formula is
Then, we have that n = 10 and r=6:
To simplify calculus, we are going to use that n! = (n-1)!n = (n-2)!(n-1)n and so on.
B is true; pi= ~3.14. 3+4 is equal to 7, so because pi is greater than 3, pi+4>7
No she didnt. She needs 12% more of .8 yards.
.8 yards x 12% more = 0.096+.8= 0.896 yards to cut
