64-8+ 12 ×2 +9

apply the rule of BODMAS
and
that means you have to solve bracket first,
then of (as in 1/2 if 12)
then division
then multiplication
and then addition,
and finally you can subtract

[BODMAS stands for bracket, of, division, multiplication, addition, subtraction]



Using BODMAS rule

64-8+ 12 ×2 +9
= 64 - 8 + 24 +9
= 97 - 8
= 89

Which expression is equivalent to -1.3 - (-1.9)−1.3−(−1.9)minus, 1, point, 3, minus, left parenthesis, minus, 1, point, 9, right
RideAnS [48]

Answer:

Choise B: -1.3+1.9

Step-by-step explanation:

For this exercise you must remember the multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

 

By definition, equivalent expression have the same value.

Then, you can find an equivalent expression to the expression provided in the exercise by simplifying it.

So, given:

-1.3 - (-1.9)

To simplify it, you can distribute the negative that is located outside of the parentheses (in order to eliminate the parentheses).

Applying this procedure, you get the following equivalent expression:

-1.3 - (-1.9)=-1.3+1.9

Therefore, as you can notice, the expression obtained matches with the one shown in Choice B.

Solve the inequality x divided by 6 is less than or equal to 3
Alja [10]
Your inequality looks like this:
\frac{x}{6}  \leq 3
To get rid of the /6, you need to multiply by 6 as the opposite operation cancels it out. So, all you need to do is multiply both sides by 6 to isolate x. 
Therefore:
x \leq 18
