When Pete had a fever, his temperature was
101.4°F. After taking some medicine, his
temperature was 99.2°F. The equation
101.4-d=99.2 gives the number of degrees
d that Pete's temperature decreased. What is
the solution of the equation?​

Respuesta :

Answer:

2.2 degrees F

Explanation:

101.4 - 99.2 = 2.2

Answer:Simplifying

101.4 + -1d = 99.2

Solving

101.4 + -1d = 99.2

Solving for variable 'd'.

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

Add '-101.4' to each side of the equation.

101.4 + -101.4 + -1d = 99.2 + -101.4

Combine like terms: 101.4 + -101.4 = 0.0

0.0 + -1d = 99.2 + -101.4

-1d = 99.2 + -101.4

Combine like terms: 99.2 + -101.4 = -2.2

-1d = -2.2

Divide each side by '-1'.

d = 2.2

Simplifying

d = 2.2
