Which method correctly solves the equation using the distributive property?

Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x minus 4 = negative 1.7. Negative 0.2 x = 2.3. x = negative 11.5.

Negative 0.2 (x minus 4) = negative 1.7. x minus 4 = 0.34. x = 4.34.

Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x + 0.8 = negative 1.7. Negative 0.2 x = negative 2.5. x = 12.5.

Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x minus 0.8 = negative 1.7. Negative 0.2 x = negative 0.9. x = 4.5.

When solving the equation, which is the best first step to begin to simplify the equation?

(negative 2) (Negative 2) (x + 3) = negative 10 (negative 2)

Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)

StartFraction negative 2 over 2 EndFraction (x + 3) = StartFraction negative 10 over 2 EndFraction

StartFraction negative 2 over negative 10 EndFraction (x + 3) = StartFraction negative 10 over negative 10 EndFraction

Which statement can be represented by the equation ?

A number, m, less than 18 is seven point two.

Eighteen decreased by a number, m, is seven point two.

A number, m, divided by 18 is seven point two.

Eighteen divided by a number, m, is seven point two.

Which equation can be used to represent the statement?Sixteen is the same as one and two-tenths times a number added to negative 8.

16 + 1.2 n = negative 8

16 + 1.2 n = 8

16 = 1.2 n + (negative 8)

16 = negative 1.2 n + 8
