MARK AS BRAINLIEST
Arisa [49]

Answer:

The answer to your question is 25%

Step-by-step explanation:

Data

Initial price = $2.00

Final price = $2.50

First we subtract the final price to the inicial price

              increment = 2.50 - 2.00

                                = $0.50    It's the amount that the school increases to the community members

            Now we use a rule of three to find the percent

                 $2.00 ----------------------  100%

                 $0.50  ---------------------    x

x = 0.50 x 100/2 = 50/2 = 25%

Write an equation for the description.
vfiekz [6]

Answer:

121=6w

Step-by-step explanation:

Formula for perimeter of a rectangle:

P=2l+2w

w = width

l = length

Since the length is twice the width,

l=2w.

So, plugging these values into the formula, as well as the given perimeter of 121 feet, we get,

121 = 2(2w)+2w

And after some simplification, we are left with,

121 = 6w

Find a formula for an arithmetic sequence that begins 80, 83, 86, 89, ...​
mel-nik [20]

Answer:

a_{n} = 3n + 77

Step-by-step explanation:

The nth term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 80 and d = a₂ - a₁ = 83 - 80 = 3 , then

a_{n} = 80 + 3(n - 1) = 80 + 3n - 3 = 3n + 77

1. Solve for the value of x
Tamiku [17]

Answer:

<h3><u>x = 18</u></h3>

Explanation:

  • Line E B C Needs To Equal 180°
  • Create An Equation

3x + 5 + 3x + 4 + 3x + 9 = 180

  • Simplify Both Sides Of The Equation

(3x + 3x + 3x) + (5 + 4 + 9) = 180( Combine Like Terms)

9x + 18 = 180

9x + 18 = 180

  • Subtract 18 From Both Sides

9x + 18 − 18 = 180 − 18

9x = 162

Divide Both Sides By 9

9x / 9 = 162 / 9

<h3><u>x = 18</u></h3>
