PLEASE HELP!

We have that
<span>If (5x-4+13x=5) -------------->  then x=1/2
Step 1
</span>let's substitute the value of x = (1/2) in the expression [5x-4+13x] and verify its result
5*(1/2)-4+13*(1/2)
(5/2)-4+(13/2)
(5-4*2+13)/2----------> (5-8+13)/2=10/2=5
then 
5=5-----------> <span>the value of x = (1/2) satisfies equality</span>

1. x + 2 = 8<br> How to solve this problem
s344n2d4d5 [400]

Answer:

Subtract two from 8, the remainder is x. In this case, it is 6.

For future questions, try to think of x as a mystery number rather than a letter. You got this. :)

Answer:

243.75

I hope i am right

Step-by-step explanation:

Using \: angle\: 40 \\Opposite = 25\\Hypotenuse = ?\\Sin \alpha = \frac{opp}{hyp} \\Sin 40 = \frac{25}{x} \\0.6427= \frac{25}{x}\\0.6427x = 25\\x = \frac{25}{0.6427}\\ x = 38.89\\x = 39\\Using \:Pythagoras\: theorem\\Hyp^2 = Opp^2 +Adj ^2\\39^2=25^2+x^2\\1521=625+x^2\\1521-65=x^2\\896=x^2\\x=29.93\\x = 30\\area = 1/2 \times b \times c \times sin(A).\\b =25\\c =39\\a =30\\A = \frac{1}{2} \times 25  \times 39 \times Sin 30\\A = 487.5\times 1/2\\A =243.75yd^2
