Answer:

x = -7

Step-by-step explanation:

Solve for x:

2 x + 3 = x - 4

Hint: | Move terms with x to the left-hand side.

Subtract x from both sides:

(2 x - x) + 3 = (x - x) - 4

Hint: | Combine like terms in 2 x - x.

2 x - x = x:

x + 3 = (x - x) - 4

Hint: | Look for the difference of two identical terms.

x - x = 0:

x + 3 = -4

Hint: | Isolate terms with x to the left hand side.

Subtract 3 from both sides:

x + (3 - 3) = -3 - 4

Hint: | Look for the difference of two identical terms.

3 - 3 = 0:

x = -3 - 4

Hint: | Evaluate -3 - 4.

-3 - 4 = -7:

Answer: x = -7

Chris purchased a tablet for $650. The tablet depreciates at a rate of $25 per month.
Troyanec [42]

Let d equal the final amount it depreciates.

Let m equal the number of months.

Since d is the final amount, we put this at the very end of the equation.

Since it depreciates $25 every month, this number is going to be subtracted from the total price of the tablet ($650).

The final equation comes out too: d = 650 - 25m

Best of Luck!

kkurt [141]
Ten is mistakenly written by Tim in question.
Gabriel is making a mixture of compost and soil. In which he wants to mix 2 part compost to 10 parts potting soil. And he wants to end up with ten kilogram
It means compost is 2 pars out of 12 and potting soil is 10 parts out of 12
so, (2 / 12) x 10 kilogram of compost is used
= 1.66667 kilogram of compost Gabriel should use.
