Answer:12
Step-by-step explanation: First you put 48 in the house then you put 4 on the outside . First you have to decide how many times 4 goes into 4 which is 1 then you have to subtract by that same number after that you bring down your next number which would be 8 so 4 goes into 8 2 times so then you have to multiply 4x2 which gives you 8 so you subtract and end of with zero . To check your answer multiply 12 and 4
5 * 10 raise to power of - 4
Your mistake was that you wrote 7x-5 and 9x-16 as 7x+5 and 9x+16. You have to add the expressions the way it is. It helps to put the parenthesis around it. So when you add (7x-5)+(9x-16)+(3x+11) you get 19x -10 =180. So 19x=190, so x=10.
G+(3/h) This is the correct answer!
