Step-by-step explanation:

if $45 is divided into the ratio 4:5 the smaller part is A. $1.50 B.$3.50 C.$4.50 D.$24.50​ Asap

Answers

Answer:

Step-by-step explanation:

When you do 45 divided by 9 you get 5.

                         45 / 9 = 5

     To figure out what the smaller number (in this the 4) equals,

  you have to do 4 times 9 to get 36.

                    4 * 9 = 36

So your answer is 36.

(3ax + 4a) - (9x + 15a)

Answers

What does the variables represent?

Answer:

3ax−11a−9x

Step-by-step explanation:

3ax+4a−(9x+15a)

Distribute the Negative Sign:

=3ax+4a+−1(9x+15a)

=3ax+4a+−1(9x)+−1(15a)

=3ax+4a+−9x+−15a

Combine Like Terms:

=3ax+4a+−9x+−15a

=(3ax)+(4a+−15a)+(−9x)

=3ax+−11a+−9x
