Angle doe and angle eof are adjacent angles. if m∠dof = 66°, m∠doe = x, and m∠eof = 27°, which equation could be used to solve for x?
a.
x + 66° + 27° = 180°
b.
x - 66° + 27° = 90°
c.
x - 27° = 66°
d.
x + 27° = 66°

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
