Evaluate the equation. 4.12 – d = 1.45
A. d = 2.67
B. d = 3.67
C. d = 5.57
D. d = 5.67

A d=2.67

Step-by-step explanation:

Simplifying

4.12 + -1d = 1.45

Solving

4.12 + -1d = 1.45

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-4.12' to each side of the equation.

4.12 + -4.12 + -1d = 1.45 + -4.12

Combine like terms: 4.12 + -4.12 = 0.00

0.00 + -1d = 1.45 + -4.12

-1d = 1.45 + -4.12

Combine like terms: 1.45 + -4.12 = -2.67

-1d = -2.67

Divide each side by '-1'.

d = 2.67

Simplifying

d = 2.67

A. 2.67

Step-by-step explanation:

d = 2.67

4.12 - 2.67 = 1.45

3x + 18 = 147°

step-by-step explanation:
