Answer: ∠REA = 53°

Step-by-step explanation:

Since ∠BEA = 71°, set both angle measures equal to that.

2x + 5x + 8 = 71

Solve for x. First, combine like terms:

7x + 8 = 71

Then, subtract 8 from both sides:

7x = 63

Divide both sides by 7:

x = 9

Now, plug x into ∠REA:

∠REA = 5x + 8

∠REA = 5(9) + 8

∠REA = 45 + 8

∠REA = 53°

Hope this helps!

Dana walks 3/5 mile in 1/4 hour. What is dana's walking rate in miles per hour?
Flura [38]
Here, our equation is 3/5 (0.6) mile per 1/4 (0.25) hour.  0.25 times 4 = 1, so we have to multiply 1/4 (0.25) 4 times to get 1 mile. To get a proportional answer, we must also multiply 3/5 (0.6) by 4. This comes out to 2.4. So her walking rate is 2.4 miles per hour.

Use the commutative property of addition to simplify 12x - 36 - 6x.
nexus9112 [7]

12x - 36 - 6x \ is \ simplified \ to \ 6(x-6)

<h2>Explanation:</h2>

The commutative property of addition states that:

a+b=b+a

So applying this property to our expression we have:

12x - 36 - 6x=-6x+12x-36 \\ \\ \\ So \ here: \\ \\ a=12x-36 \\ \\ b=-6x \\ \\ \\ Combining \ like \ terms: \\ \\ 12x - 36 - 6x=6x-36 \\ \\ \\ Common \ factor \ 6: \\ \\  12x - 36 - 6x=6(x-6) \\ \\ \\ Finally: \\ \\ 12x - 36 - 6x \ is \ simplified \ to \ 6(x-6)

First, you cross multiply then that will give you

9x - 3 = 5x + 5

collect like terms

9x - 5x = +5 + 3

= 4x = 8

Divide both sides by the coefficient of x that's 4

= 2
