He didn’t follow PEMDAS which is the an acronym for the order of operations. according to pemdas the first step is parenthesis (which is the p in pemdas) there fore the first step is to add the 1 and the 2
then since there are no exponents you multiply so you multiple 5(3) which is 15
then you can add all the number left to right
so 15+2+3= 20
so the answer is 20
hope this helped
let me know if you have any questions
The product of two numbers and the product of their greatest common factor and least common multiple are always equal.
Let the other number = X.
Greatest common factor is 6
Least common multiple is 36
We now have 6 * 36 = 12 * x
Simplify:
216 = 12x
Divide both sides by 12:
x = 216 / 12
x = 18
The other number is 18.
It is a cluster from $1.00 to $7.00 and had no gaps
4768 x 1551 is 7395168
7395168 divided by 10.2 is 725016.5 (rounded to the nearest tenths)
<span>If you imagine a straight line, with -9 all the way on the left, then mark along the line in one number increments until you get up to 7, you will find that in total the line is 16 segments in total. Mathematically, this is a question of absolute value, ie absolute value of -9 = +9, and therefore 9 + 7=16.</span>
