Dan bought a new house with a backyard whose dimensions are 21.8 by 12 feet. The backyard has a triangular garden with an area o

f 34.56 square feet. Dan wants to cover the backyard with seeds so that the grass will grow. If he does not need to cover the garden, how many bags of seed must he purchase to cover the rest of the backyard if one bag covers 16 square feet?

Well first, let's find the total area of the back yard.  Given the dimensions, we can assume the yard is rectangular.
Area = 21.8(12) = 261.6ft²

Now we can find the area that will need to be seeded by subtracting the area of the garden from the total area:
261.6 - 34.56 = 227.04ft²

Finally, we can divide this area by 16ft² to find the number of bags of seed we will need.  
227.04 ÷ 16 = 14.19 bags  or little more than 14 bags.. Looks like we better buy 15 bags of grass seed to do the job..

Find the equation of a line that is parallel to y = 2x + 3 and passes through (-1, -1).
drek231 [11]

Answer:

  y = 2x +1

Step-by-step explanation:

The given line is in "slope-intercept" form, where the slope is the coefficient of x, 2, and the intercept is the added constant, 3. The parallel line will have the same slope, but its constant will be different. We can find the constant by putting the given point into an equation with the constant as the unknown:

  y = 2x + b

  -1 = 2(-1) +b . . . substitute for x and y

 2 -1 = b . . . . . . add 2

  1 = b

So the equation for the parallel line is ...

  y = 2x + 1

Solve the equation. Find x.<br> 20x + 5 - 0 = 5x + 32.5*2
SVEN [57.7K]

Answer:

x = 4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

20x+5−0=5x+(32.5)(2)

20x+5+0=5x+65

(20x)+(5+0)=5x+65(Combine Like Terms)

20x+5=5x+65

20x+5=5x+65

Step 2: Subtract 5x from both sides.

20x+5−5x=5x+65−5x

15x+5=65

Step 3: Subtract 5 from both sides.

15x+5−5=65−5

15x=60

Step 4: Divide both sides by 15.

15x

15

=

60

15

x=4

Hope this helps!

Can someone help me?<br><br> Brainlest for anyone who helps and explains<br><br> Thank you!!
Xelga [282]
The answer would be 10. Explanation: So basically you add the two complementary angles and set it equal to the whole thing. So it would look like 4x+46=7x+16. Then, you have to solve for x. To do that, subtract the 4x from both sides and the 16 from both sides. That will leave you with 3x=30. Then, divide by 3, and you get an answer of 10. Hope that helped :)
