How are rational exponents and roots similar
stellarik [79]

They are similar in basically everything because they're inverse operations.

Inverse operations are operations that do the smae thing, but the opposite way. If one multiplies, the other one divides. If one sums the other one subratcts.


→ Exponents multiply the same number by itself a given amount of times to obtain the answer.

→ Roots get a number and look for another one that multiplied by itself a given amount of times reult in the initial number.


Hope it helped,

Answer:

Angle A = 19

Step-by-step explanation:

Vertical angles are congruent ( equal to each other )

If angle A and angle B are vertical angles and vertical angles are congruent then angle A = angle B

If angle A = 3x + 13 and angle B = 5x + 9 then 3x + 13 = 5x + 9

( Note that we just created an equation that we can use to solve for x )

We now solve for x using the equation created

3x + 13 = 5x + 9

Step 1 subtract 3x from both sides

Outcome: 13 = 2x + 9

Step 2 subtract 9 from both sides

Outcome: 4 = 2x

Step 3 divide both sides by 2

Outcome: x = 2

Now to find Angle A

All we have to do to find the measure of angle a is simply substitute 2 for x in it's given expression ( 3x + 13 )

Substitute 2 for x

Angle A = 3(2) + 13

Multiply

Angle A = 6 + 13

Add

Angle a = 19

What is 7 1/5 - 6 2/5 =?
CaHeK987 [17]

In my opinion, I like using improper fractions, but that's up to you:

7 1/5 = 36/5

6 2/5 = 32/5

36/5 - 32/5 = 4/5
