Answer:

A. because if you take 265,000 and multiply by 5,880,000,000,000 you will get 1,558,200,000,000,000,000 and put into scientific notation is 1.5582 X 10E18 (which means to the power of 18) which makes the answer A. also I know I'm late I was stumped myself and decided to actually apply myself and look at me now

How to work out 0.4x+2.9=1.5 plz show work

Nataly [62]

Answer:

x = -3.5

Step-by-step explanation:

Simplifying

0.4x + 2.9 = 1.5

Reorder the terms:

2.9 + 0.4x = 1.5

Solving

2.9 + 0.4x = 1.5

Solving for variable 'x'.

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

Add '-2.9' to each side of the equation.

2.9 + -2.9 + 0.4x = 1.5 + -2.9

Combine like terms: 2.9 + -2.9 = 0.0

0.0 + 0.4x = 1.5 + -2.9

0.4x = 1.5 + -2.9

Combine like terms: 1.5 + -2.9 = -1.4

0.4x = -1.4

Divide each side by '0.4'.

x = -3.5

Simplifying

x = -3.5
