X+5-8=12
This is the equation you use. Then add 8 from both sides. You get x+5=20 then subtract 5 from both sides and you'll get x=15 which is the number. Hope it helps and mark as brainliest!

What is the solution of the equation 17 = 3x − 4?
pogonyaev

Answer:

<em>x = 7</em>

Step-by-step explanation:

Simplifying

17 = 3X + -4

Reorder the terms:

17 = -4 + 3X

Solving

17 = -4 + 3X

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '-3X' to each side of the equation.

17 + -3X = -4 + 3X + -3X

Combine like terms: 3X + -3X = 0

17 + -3X = -4 + 0

17 + -3X = -4

Add '-17' to each side of the equation.

17 + -17 + -3X = -4 + -17

Combine like terms: 17 + -17 = 0

0 + -3X = -4 + -17

-3X = -4 + -17

Combine like terms: -4 + -17 = -21

-3X = -21

Divide each side by '-3'.

X = 7

Simplifying

X = 7

What is the volume of the triangular prism <br><br> A) 12 cm<br> B) 18<br> C) 24<br> D) 48
lisov135 [29]

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.
For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.
So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h
