Mathematics

Answer:

C

Step-by-step explanation:

-0.2(x-20)=44-x

Divide both sides by -0.2:

x-20=-220+5x

Subtract x from both sides:

-20=-220+4x

Add 220 to both sides:

200=4x

x=50, or answer choice C. Hope this helps!

x = 50

Isolate the variable by dividing each side by factors that don't contain the variable. x=50 this is helpful

Solve |2x – 3| = 11. Show each step of your work.
Klio2033 [76]

Answer:

x =7       or              x = -4

Step-by-step explanation:

|2x – 3| = 11

There are two solutions to an absolute value equation, one positive and one negative

2x-3 =11    or 2x-3 = -11

Add 3 to each side

2x-3+3 = 11 +3    2x-3+3 = -11+3

2x = 14                 2x = -8

Divide each side by 2

2x/2 =14/2           2x/2 = -8/2

x =7                     x = -4
