Enter the value for x that makes the equation 1/2 (4x+12)+5x=30 true.

First, distribute the (1/2) into (4x+12) by multiplying them.

The equation becomes:

2x + 6 + 5x = 30

On the left side, combine “like terms” through addition.

7x + 6 = 30

Subtract 6 from both sides:

7x = 24

Finally, get x alone by dividing both sides by 7:

x = 24/7, or if you wanted to round the decimal answer, it’s about 3.429.

HELP ME PLEASE IVE BEEN STRUGGLING WITH THIS FOR SO LONG
Ber [7]

Answer:

<h2>m∠ACE = 90°</h2>

Step-by-step explanation:

Figure Interpretation:

m∠CBA + m∠CDE = 180

m∠BCA = (180-m∠CBA)/2

m∠DCE = (180-m∠CDE)/2

=======================

Then

m∠BCA + m∠DCE = (180-m∠CBA)/2 + (180-m∠CDE)/2

                                = [360-(m∠CBA+m∠CDE)]/2

                                = [360 - 180]/2

                                = 90

finally,

m∠ACE= 180 - (m∠BCA + m∠DCE)

             = 180 - 90

             = 90

Simplify each expression using an exponent rule learned in class. <img src="https://tex.z-dn.net/?f=%28%5Cfrac%7By%7D%7Bx%7D%20%

Hey there! I'm happy to help!

If you raise a fraction to an exponent, you apply that exponent to the numerator and the denominator. This would give us \frac{y^4}{x^4}.

Have a wonderful day! :D

Answer:

1 = 52

2 = 68

3 = 40

4 = 25

Step-by-step explanation:

1 = (4 + 3)^2 + (12 / 4)

7^2 + 3

49 + 3

= 52

2 = (12 x 9 - 7^2) + 9

(108 - 49) + 9

59 + 9

= 68

3 = (30 - 2) / 7 + 6^2

28 / 7 + 36

4 + 36

= 40

4 = (2 x 7 + 4^2) - 5

(14 + 16) - 5

30 - 5

= 25

Hope this helps!! Brainliest plz??
