According to the text, 1 bag of grass seed = 1/6 of the lawn. So if this is right, then it will take 6 bags of grass seeds to cover 1 lawn.
<span>1. B. 2.5x
2. A. 1/2 y- 4
3. D. v=15.00n </span>
In this problem why is the easiest to substitute.
Just set the equations equal to each other because they both equal y
-x + 4 = 2x - 8
(You want to get all the x's to one side so add x to each side)
4 = 3x - 8
(next add 8 to both sides)
12 = 3x
(lastly divide 3 from both sides)
4 = x
You have got your x so now it is time to find that y just replace x to either of the two equations
y = 2(4) -8 or y = -(4) + 4
y = 8 - 8 y = 0
y = 0
Final Answer: y=0, x=4
The student made a mistake in Line 1: AC=2, DF=2 AC ≅ DF .
Foil the equation; j*k, j*-5, 7*k, 7*-5, once you foil add like terms.
jk - 5j +7k - 35 is the final answer
