The area of a playground is 204 yd^2 The width of the playground is 5 yd longer than its length. Find the length and width of the playground.

Answers

Answer:

12

Step-by-step explanation:

Assuming that the shape of the playground is rectangular, we know that the area of a rectangle is length x width.

Let the length = x

width = x + 5

x(x + 5) = 204

x² + 5x = 204

x² + 5x - 204 = 0

(x + 17)(x - 12) = 0

x = -17 and x = 12

However, since x represents the length of the playground, length cannot be negative. The only value possible is x = 12.

Therefore, the playground has a length of 12 yd and a width of 12 + 5 = 17 yd.

Answer:

length = 17 yd, width = 12 yd

A cell phone company charges a monthly fee plus $0.25 for each text message. The monthly fee is $30.00 and you owe $59.50. How many text messages did you have? Write an equation using x as the variable and then solve the equation.

Answers

Ok if he paid.

59.50-30.00=29.50

so he paid 29.50 dollars more 

29.50/0.25=118

so he texted 118 times
.25x + 30 = 59.50 is the equation.

now subtract 30 from each side leaving you with:

.25x = 29.50

now divide by .25 on each side.

x = 118
      
You sent 118 text messages.

Maria is making blueberry muffins using a blueberry cake recipe. To make the muffins, she has to divide the cake recipe in half. If the cake recipe calls for 2/3 cup of milk, which expression can Maria use to caluculate how much milk she needs to make the muffins?-
A - 1/2 divided by 2/3
B - 2/3 x 2
C - 2/3 x 1/2
D - 2 divided by 2/3

Answers

I think she would have to divide 2/3 by 1/2. So you would do 2/3 x 2/1 and since 2/1 is equal to 2 the answer would be BHope this helped - Ashlynn

Rico is making4 batches of mexican rice. each batch needs 2/3cup of corn. He only has a1/3-cup measure.How manytimes must Rico measure 1/3cup of corn to have enough fr all ofMexican rice?

Answers

If each batch needs 2/3 cups of corn and he only has only 1/3 cup measure,
1/3 + 1/3 = 2/3. Fraction addition and all that, adding the top numbers but not the bottom.

So you need 2 "1/3" measures to make a 2/3 cup of corn. You need 4 sets of this 2/3 cup measure, so multiply:
2 (the number of measures per batch) and 4 (the number of batches).

That's the long explanation for the short answer: 8.

Hope that helped!~
