starting today, she will collect 25 seashells each week.
what will be the total number of seashells in sally’s collection after 5 weeks?
show or explain how you got your answer.
write an expression to represent the total number of seashells in sally’s
collection after w weeks.

The total number of seashells in Sally’s collection after 5 weeks is 225 and an expression to represent the total number of seashells in Sally’s  collection after w weeks is  

Step-by-step explanation:

Sally has seashells currently = 100

From today , she will collect 25 seashells each week.

Let w be the no. of weeks

So, she will collect seashells in w weeks = 25w

So, total seashells after w weeks = 100+25w

Let y denotes total seashells after w weeks

So,

Substitute w = 5

Hence the total number of seashells in Sally’s collection after 5 weeks is 225 and an expression to represent the total number of seashells in Sally’s  collection after w weeks is  

you cant answer this dummy

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
