Solve 6[4x(72-63)divided3]

1 answer:

3 0

Parentheses first, 72-63 is 9 next multiply by 4 which is 36 the you’ll divide by 3 now you have 12 so multiply that by 6 and you get 72. Just a hint, another way to write that without using the multiply or the divided would be 6[4(72-63)/3] but either way you want is fine. Hope this helped :)

A jar contains $36.25 in quarters and nickels. How many quarters and dimes are in the jar? Please explain how u got the answer,

kumpel [21]

So, look:

36*4 = 144

There are 145 quarters in all.

And in nickels, there are:

144 * 5 = 720 + 5 = 725
There are 725 nickels in all.

Dimes: 144 * 10 = 1440 + 10 = 1450 (or you could do 145 * 10 and still get 1450. Like I did in the nickels and everything. :) )

= 1450 dimes

I hope this helps!

Answer:

Mary's brother practiced 4 times as long.

Step-by-step explanation:

Mary practiced violin for 2 hours.

Her brother practiced trombone t times as long or 8 hours.

t times of 2 hours = 2t hours

But, 2t = 8

Divide both sides by 2.
