Answer:
<em>5.195</em>
Step-by-step explanation:
To solve the different operations of a mathematical expression there are rules that must always be followed, that is, there is a hierarchy of operations that must be respected.
The hierarchy of operations works as follows:
First, operations in brackets, brackets or braces are resolved independently.
Next, the powers and roots are realized.
It continues to solve multiplications and divisions.
Finally, the addition and subtraction are carried out, regardless of the order.
6 x 0.9 + 0.1 / 4 -0.23 =
First, multiplications and divisions:
5.4 + 0.025 - 0.23.
Then, addition and subraction:
5.195
Answer:
x= -45/4 or -11.25 or -11 1/4
Step-by-step explanation:
-3=4x+42
4x=-45
x=-45/4
6. 1/2 divide 7 by both #
7. 1/4 divide 2 by both#
8. 2/3 divide 8 by 4, then divide 24 by 4 to get 4/6 to reduce it divide 2 by both #
9. 5/7 divide 3 by both #
10. 3/4 divide 18 and 24 by 3= 6/8 then divide these two # by 2
Haha, there isn't a thing that makes you 'really smart'.
However, you can grow and improve your knowledge.
The more challenging material you expose yourself to, while putting in the effort to solve them, there's no doubt you'll definitely improve!
+ you can try exercising your brain every now and then by playing trivia games or reading books- do whatever interests you and helps you learn!
