Subtract 2d from both sides

simplify 10 + 2.5d - 2d to 10 + 0.5d

subtract 10 from both sides

simplify 4 - 10 to -6

divide both sides by 0.5

simplify 6/0.5 to 12

switch the sides

PLEASE HELP MI AMOR ILL LOVE YOU FORVER I SWEAR
NemiM [27]

Answer:

x = 8

z = 65

Step-by-step explanation:

Through various rules, we are able to assert: (6x + 67)° = 115°.

Now, we want to solve for x:

6x + 67 = 115

6x = 48

x = 8

We know that z° is equal to the complement of (6x + 67)°, and together these must sum to 180°. Therefore, we can simply take 180° - 115° to find that z° = 65°.
