2(x-5)+8=4<br><br>what does x equal?​
Ostrovityanka [42]

Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(x−5)+8=4

(2)(x)+(2)(−5)+8=4(Distribute)

2x+−10+8=4

(2x)+(−10+8)=4(Combine Like Terms)

2x+−2=4

2x−2=4

Step 2: Add 2 to both sides.

2x−2+2=4+2

2x=6

Step 3: Divide both sides by 2.

2x/2 = 6/2

x=3

Solve for R<br><br> 3 r + 4 <br> ---------- = 5 <br> 2<br><br> r = ?
lakkis [162]
To find r, first write out the equation:
\frac{3r+4}{2} =5
Next, multiply both sides by 2:
3r+4=10
Now, subtract both sides by 4:
3r = 6
Divide both sides by 3:
r=2

The answer to this problem is r = 2. Hope this helps and have a phenomenal day!

The width of a box is x units.
wariber [46]

Answer:

3x² + 30x

Step-by-step explanation:

width of a box = x units.

height of a box = 3 units.

length of a box = (x + 10) units.

Volume of the box = length × width × height

= (x + 10) * x * 3

= (x + 10) * 3x

= 3x² + 30x

Volume of the box = 3x² + 30x
