Answer:
(x, y) = (3, 5)
Step-by-step explanation:

Solving by elimination here again, there are 2 good options available. Either multiply the whole bottom equation by -1 to cancel the x, or by 2 to cancel the y. I'll do the latter:

Add from top to bottom:

Now, with the value of x, solve for y in either of the equations. I'll choose the second one here:

(x, y) = (3, 5)
Answer:
m < b = 76
Step-by-step explanation:
Because b is directly across from the 76 degree angle, that makes them vertical angles, which means they are the same degree I believe.
Answer:
5 cups
The Commutative Property of Addition
Step-by-step explanation:
They have a common denominator of 12
21/12+6/12+20/12+4/12+3/12+6/12=60/12=5 cups
or you could group ingredients with the same denominators
7/4+1/4+1/2+1/2+5/3+1/3=
8/4+2/2+6/3=
2+1+2=5
The Commutative Property of Addition says the order of the numbers doesn’t change the outcome.
2x + (x+9) = 90
3x + 9= 90
3x= 81
x= 27
Now plug in 27 to (x+9)
27+9= 36
Final Answer = 36
A. C= K-273.15
b. 300= C+273.15
300-273.15= C
26.85=C
