Multiply 3.28 by five and multiply 4.26 by three the add those two and that is ur answer 16.40mb
Solution :
It says multiply 8 by 12 and then add 9
reading the sentence it is clear that priority is given to multiplication of 8 and 12 , once it is done then we would add 9 .
Let us first write multiplying 8 and 12 which makes it 8 x 12
the result is being add to 12 so we place 8x12 in parenthesis then add 12
which , makes it : ( 8x12) + 9
this matches to now of the given options so it is because multiplication is always given a priority comparing to addition so here parenthesis is not that important .
we can write it without parenthesis like : 8x12 +9
Answer is third option .
There is a sign missing, but I think it's a "+" like this:
8-(2+5)
H, ,that is Harry's answer would be:
first the bracket:
8-(7)
and then the whole expression:
8-(7)=1, so H=1
Terry's answer would be:
8-2+5, which we do from left to right:
6+5=11, so T=11
then H-T is 1-11, which is -10.
I believe it’s B because everything equals 180 and then 180-70=10
4^3= 64
2^6= 64
Therefore, n=6.
You can also figure this out if you know that 2^3*2^6=2^9. When you multiply exponents with the same base, add the exponents. 3+6=9
Final answer: n=6
