Answer:
x= 67 degrees
Step-by-step explanation:
all of the angles of a triangle have to add up to 180 degrees.
180 - 75 - 38 = 67
Answer: 20x+12
Step-by-step explanation:
Distribute the three: 3(7x+4) will be changed to 21x+12-x
Next group like terms, -x+21x=20x
The new equation will be 20x+12
Substitution is where you solve for one of the variables and then plug that in for the same variable in the other equation. Here, there is already an equation that is solved for a variable,
. So we can plug in '4x - 11' for 'y' in the other equation:
Distribute 5 into the parenthesis(multiply it to every term in the parenthesis):
Your answer is
C.
