Answer:
20
Step-by-step explanation:
Remember PEMDAS!
So first parentheses:
1.6^2 = 2.56
8.7 + 9.3 = 18.
Because that is inside another parentheses you multipy them.
2.56 x 18 = 46.08
Now: 46.08 divided by 1.8 = 25.6
Now subtract:
25.6 - 3.7 - 1.9 which equals 20!
Hope that helped!
So divide factions ex: 6/2 divide 3/2 will bring down the first faction 6/2 then the always flip the second faction 2/3 to make it 2/3 the you have 6/2 divide 2/3, now you multiple 6/2 times 2/3 so how many times does 3 go in6 so the 3 will be 1 and the 6 will be 2 now 2 and 2 both will come 1 because 2 goes in both of them 1 time and the answer is 2/1
Answer:
180
Step-by-step explanation:
5 +4 = 9

The last one
Step-by-step explanation:
the one with b=7 & h=5 because you have to multiply both numbers together , so you multiply and then see the smallest answer
