Step-by-step explanation:

Answer: 200+7 * X=
Step-by-step explanation:
Well so you have to go with pemdas. p parenthesis, e exponets,m multipication, d division, a add, s subtract. let start with the parenthesis which is 8 plus negative four to the secondpower minus 6. so negative 4 to the second power is equal to positive sixteen because negative time negative is equal to positive. so 8 plus sixteen is 24-6 is 18. negative 12 divided by 3 is negative 4.so negative 4 time 18 is negative 72 plus 2 is negative 70.the answer is negative 70
Answer:
x=81
y=99
z= 129
Step-by-step explanation:
the 3 angles of a triangle add to 180 degrees
51 + 48 + x = 180
99 + x = 180
subtract 99 from each side
99 + x -99 = 180 -99
x = 81
x+y = 180 they make a straight line
81+ y = 180
subtract 81 from each side
y = 180-81
y = 99
z+ 51 = 180 they make a straight line
subtract 51 from each side
z+51-51 = 180 -51
z = 129
