Answer:

r = -3

Step-by-step explanation:

Simplifying

5r + 15 = 0

Reorder the terms:

15 + 5r = 0

Solving

15 + 5r = 0

Solving for variable 'r'.

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

Add '-15' to each side of the equation.

15 + -15 + 5r = 0 + -15

Combine like terms: 15 + -15 = 0

0 + 5r = 0 + -15

5r = 0 + -15

Combine like terms: 0 + -15 = -15

5r = -15

Divide each side by '5'.

r = -3

Simplifying

r = -3

Teddy has 23 boxes of juice packed and plans to pack 3 additional boxes each hour. Charely has 7 boxes packed and plans to pack
Vadim26 [7]
The equation is already set up for you. All you need to do is solve for x, the number of hours.

23 + 3x = 5x + 7 original equation
23 - 7 = 5x - 3x combine like terms by subtracting 7 and 3x from both sides
16 = 2x simplify
16/2 = x divide both sides by 2 to isolate x
8 = x solve for x
Therefore, the answer is 8 hrs.

PLEASE HELP DUE TOMORROW!!!!!!​

Answer:

X=35

Step-by-step explanation:

X=35 because a straight line is 180 degrees. Take away 60 degrees and you're left with 3x + 15 = 120. Simplify to 3x=105, and then divide 3x by 3. Do the same to the other side. X will now equal 35. Hope this helps :)
