Which statement about N must be true?

Mathematics
1 answer:
rjkz [21]3 years ago
3 0

Answer: N=15

Step-by-step explanation: This is because (4n-18) when solved needs to equal 42. So when solving this you would change the equation to 42=4n-18 and then you need to isolate n. In order to do that you do the opposite so your equation becomes 42+18=4n or (60)=4n. And then you divide 60/4 and get n by itself. Therefore N=15.

Rom4ik [11]

Given the diameter of the circular garden, the area of the garden is 28.36 yd².

<h3>What is the area of the garden?</h3>

The area of a circle is expressed as; A = πr²

Given that;

  • Diameter d = 6yd
  • Radius r = d/2 = 6yd/2 = 3yd
  • Area A = ?

A = πr²

A = 3.14 × (3yd)²

A = 3.14 × 9yd²

A = 28.36 yd²

They need to raise $1,680 for travel expenses. Each chocolate bar is being sold for $2, and each box contains 30 chocolate bars.
leonid [27]

Answer:

Each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses

Step-by-step explanation:

Let x denotes number of boxes to be sold by each scholar to raise enough money to cover the team's travel expenses.

Number of scholars = 7

Total number of boxes =7x

Total number of chocolate bars =(7x)(30)=210x

Price of 1 chocolate bar = $2

Price of 210x chocolate bars =210x(2)=\$420x

Also,

Total amount to be raised for travel expenses = $1680

So,

1680=420x\\x=\frac{1680}{420}\\ x=4

Therefore,

each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses
