Hello!

3x + 5 = x - 10
Solve for x by isolating the variable.
Subtract 5 from both sides:
3x + 5 - 5 = x - 10 - 5
3x = x - 15
Subtract x from both sides:
3x - x = x - x - 15
2x = -15
Divide both sides by 2:
2x /2 = -15 / 2
x = -15/2.
Answer:
(4+1) x (12 x 7)
420
The only way to get this answer is to use trial and error
Answer:
=4s+10t
Step-by-step explanation:
4s has no like terms so we divide by 10 and that gives us 4.
100t has no like terms so we divide 100 by 10 that gives us 10. This means that our total answer is (4s+10t). Hope this helped! If it did can I have brainliest thx.
The volume is 675 because when you multiply 20x15 you get 300 and when you multiply 25x15 you get 375. When you add 375+300 you get 675 as your volume.
X and y = 4
