A=LxW, but first you should convert the mixed fractions to improper fractions:
7/3 x 27/5 = 189/15 = 12 6/10 = 12 3/5 square inches

P = L+L+W+W here I would convert to improper fractions, but then you need to find a common denominator.
P = 7/3 + 7/3 + 27/5 + 27/5 = 14/3 + 54/5 = 70/15 + 162/15 = 232/15 = 15 7/15 inches

Area: If you multiply 2 1/3 by 5 2/5, you get an answer of about: 12.6, which means the area is about: 12.6in. squared.
Perimeter: If you add 2 1/3+ 2 1/3+ 5 2/5+ 5 2/5 you get an answer of about: 15.47. So, the perimeter is about 15.47in.

Note: If you aren't allowed to use a calculator on this test, you should probably multiply the numbers yourself so you get show the work and get the answer in a fraction, which is probably what they want. If you are allowed to use calculators, all the information you need is right here.

Susan bought some potted plants. Petunias cost $7 per pot and begonias cost $8 per pot. She bought 22 potted plants and spent a
r-ruslan [8.4K]

Answer: she bought 13 petunias

Step-by-step explanation:

Let x represent the number of Petunias pot of flowers that she bought.

Let y represent the number of begonias pot of flowers that she bought.

She bought 22 potted plants. This means that

x + y = 22

Petunias cost $7 per pot and begonias cost $8 per pot. She spent a total of $163. This means that

7x + 8y = 163 - - - - - - - - - - - -1

Substituting x = 22 - y into equation 1, it becomes

7(22 - y) + 8y = 163

154 - 7y + 8y = 163

- 7y + 8y = 163 - 154

y = 9

x = 22 - y = 22 - 9

x = 13

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 6) and (x₂, y₂ ) = (8, 4)

m = \frac{4-6}{8-3} = - \frac{2}{5}, hence

y = - \frac{2}{5} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (8, 4), then

4 = - \frac{16}{5} + c ⇒ c = 4 + \frac{16}{5} = \frac{36}{5}

y = - \frac{2}{5} x + \frac{36}{5} ← equation of line
