Answer:

7 will be the answer.

5a+55°=90°

5a=90°-55°

5a=35°

a=35°/5

Anyone know inverse operations, cause I am confused, I looked online and it said
bija089 [108]

Answer:

For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.

Inverse operations are also very helpful for linear equations.

To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.

Ex:

13 - 2 = 11    (now change plus to minus)

13 + 2 = 11      (not the answer yet)

Now we switch the first number with the answer!

11 + 2 = 13

Hope this helped, I tried to explain it easily.

If a is a positive integer and b is a negative integer, which expression must be positive?
nydimaria [60]

So, let's solve all of them and see:

a - (-b) = a + b ⇒ can be either positive or negative, depending on the numbers

a + (-b) = a - b ⇒ can either be positive or negative, depending on the numbers

a * (-b) = a * (-b) ⇒ negative answer no matter what

a / (-b) = a / (-b) ⇒ negative answer no matter what


So the answer is:

<em>"None of the above"</em>.


Hope it helped,
