Answer:

n=3/5

Step-by-step explanation:

3n-3+10+2n=10  Combine like terms.

5n+7=10              Subtract 7 from both sides.

    <u>-7  -7</u>

5n=3                    Divide both sides by 5.

<u>/5  /5</u>

n=3/5

Hope this helps and have an amazing day ^^

Answer:

n=3/5

Step-by-step explanation:

3n−3+10+2n=10

Step 1: Simplify both sides of the equation.

3n−3+10+2n=10

3n+−3+10+2n=10

(3n+2n)+(−3+10)=10(Combine Like Terms)

5n+7=10

5n+7=10

Step 2: Subtract 7 from both sides.

5n+7−7=10−7

5n=3

Step 3: Divide both sides by 5.

5n /5

= 3 /5

n= 3 /5

frozen [14]

In a directly proportional relationship, increasing one variable will increase another. The weight of the roof whose depth is 1.75 inches is 6,300 pounds.

<h3>What is the directly proportional relationship?</h3>

In a directly proportional relationship, increasing one variable will increase another. This directly proportional relationship between p and q is written as p∝q where that middle sign is the sign of proportionality.

Let there are two variables p and q. Then, p and q are said to be directly proportional to each other if p = kq, where k is some constant number called the constant of proportionality.

Given the hail's weight varies directly with its depth. Therefore, the relation can be written as,

Weight ∝ Depth

W∝D

Introducing the constant to remove the proportionality we will get the equation as,

W = kD

1800pounds = k × 0.5 inches

3600ponds/inches = k

Now, the weight of the roof whose depth is 1.75 inches can be written as,

W = kD

W = 3600 × 1.75

W = 6,300 pounds

Hence, the weight of the roof whose depth is 1.75 inches is 6,300 pounds.
