Answer 1
Answer:

Answer:

From what I can comprehend I believe the answer is 3.2x + -4

Step-by-step explanation:

0.4(2x-9) = 0.8x - 9

0.8x - 9 - 0.6(4x+5)=

0.8x - 9 + 2.4x+5

0.8+2.4 = 3.2x

-9 + 5 = -4

3.2x + -4

M.s. alonso ordered 4,000 markers for her store. Only 1/10 of them arrived. How many markers did she receive?

Answers

M.s. alonso ordered 4,000 markers for her store. Only 1/10 of them arrived

(1)/(10) of markers arrived

Ordered markers = 4000

she received = (1)/(10) of ordered marker

= (1)/(10) * 4000 = (4000)/(10)= 400

So, M.s. alonso received 400 markers.

She received 400 markers. 

To find this:
.1 x 4000 = 400
