Answer:

x=-4

Step-by-step explanation:

(x+4) ^ (1/3) + (2x+8) ^ (1/3) = 0

Subtract (x+4) ^ (1/3) from each side

(x+4) ^ (1/3) - (x+4) ^ (1/3)+ (2x+8) ^ (1/3) = -(x+4) ^ (1/3)

(2x+8) ^ (1/3) = -(x+4) ^ (1/3)

Cube each side

(2x+8) ^ (1/3) ^3= -(x+4) ^ (1/3)^3

2x+8 = -(x+4)

Distribute the negative sign

2x+8 = -x -4

Add x to each side

2x+8 +x =-x+x-4

3x+8 = -4

Subtract 8 from each side

3x+8-8 =-4-8

3x =-12

Divide by 3

3x/3 = -12/3

x = -4

Serjik [45]

Answer: Required equation: 400+25x = 2100

Variable: x = Number of days to donate 2100 pounds.

Step-by-step explanation:

Let x = Number of days.

y = Total pounds of food donated in x days.

Given: Initial amount of food = 400 pounds

Pounds of food donated per day = 25

Total food = Initial amount of food + (Pounds of food donated per day ) (Number of days)

y =  400+25x

Their goal is to collect 2100 pounds.

2100 = 400+25x  [Substitute y= 2100]

Required equation: 400+25x = 2100

Variable: x = Number of days.

Geometry and I need help
Yanka [14]

Answer:

y = 11

Step-by-step explanation:

We use the definition of Supplementary Angles and Adjacent Angles.

Step 1: Set up equation 1 (Definition of Supplementary Angles)

5x - 4 +7x - 8 = 180

Step 2: Solve for <em>x</em>

12x - 4 - 8 = 180

12x - 12 = 180

12x = 192

x = 16

Step 3: Plug in <em>x</em>

5(16) - 4

80 - 4

76°

Step 4: Set up equation 2 (Definition of Supplementary Angles)

76 + 9y + 5 = 180

Step 5: Solve for <em>y</em>

9y + 81 = 180

9y = 99

y = 11
