If the measure of is and x = 30, which expression could represent the measure of ?

If the measure of BEC is (2x+3) and x=30, which expression could represent the measure of AED?

(3x-27) will represent the measure of AED.

Step-by-step explanation:

Given:

Measure of  

The value of 'x' =

We have to find the expression which could represent the measure of .

Measure of   (vertically opposite angle property).

Lets measure the numeric value of by plugging the value of 'x' in the expression given.

⇒

⇒

⇒

⇒

Now plugging the value of 'x' in the expressions given in the options we have to check whether any of the expression is equivalent to or not.

⇒

⇒

⇒

⇒

⇒

So (3x-27) is the appropriate choice.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
