Answers

Answer:

2s + t = 23.5

Step-by-step explanation:

There are two types of shortboards:

  • standard
  • technical

Let the width of a standard shortboard be represented by s.

Similarly, Let the width of a technical shortboard be represented by t.

As per the given information: total width of two standard shortboards

and a technical shortboard is 23.5 inches.

Representing it as an equation in terms of the variables defined:

2s + t = 23.5

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
