Answer:

-15

Step-by-step explanation:

First combine like terms, aka the variables

-5n+4n-7=8

-1n-7=8

Then, isolate the variable by adding 7 to both sides

-1n-7+7=8+7

-1n=15

Finally, solve by dividing both sides by -1

-1n/-1=15/-1

n=-15

Answer:

n = -15

Step-by-step explanation:

I'll try my best to explain how I solved this

Equation:

-5n + 4n -7=8

Add the light terms on each side:

-n -7 =8

Separate the variables from the numbers:

-n = 15

Do the operation necessary to solve it:

n = -15

grandymaker [24]
Given:
2 pythons : 6 ft each
3 corn snakes : same length
Total length = 21 ft.

Let x be the length of one corn snake.

2(6ft) + 3x = 21 ft
12ft + 3x = 21 ft
3x = 21 ft - 12 ft
3x = 9 ft
x = 9ft/3
x = 3ft

Each corn snake is 3 ft long.

3x + 12ft = 21ft

2. Brian is filling a conic container with water. He has the container half full. The radius of the container is 5 inches and th
MakcuM [25]

Answer:

current volume of the water = 785.714 in²

Height of new container = 10 inches

Step-by-step explanation:

Radius of the container = 5 inches

Height of the container = 20 inches

Volume of the container = πR²H = (22/7) × 5² × 20 = 1571.428571428 in²

Since the container is half filled with water, volume of the water = 1571.428571428 ÷ 2 = 785.714 in²

b. Volume of cylinder = πR²H = volume of water from first container = 785.714 in²

Hence 785.714 = (22/7) × 5² × H

H = (785.714) ÷ [(22/7) × 25] = 10 inches

Height of new container = 10 inches
