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.
Answer:
P in terms of V is:
P = 432/V
Step-by-step explanation:
We know that y varies inversely as x, we get the equation
y ∝ 1/x
y = k/x
k = yx
where k is called the constant of proportionality.
In our case,
P is inversely proportional to V
Given
P = 18
V = 24
so
P = k/V
k = PV
substituting P = 18 and V = 24 to determine k
k = 18 × 24
k = 432
now substituting k = 432 in P = k/V
P = 432/V
Therefore, P in terms of V is:
P = 432/V
Answer:
x=-4
Step-by-step explanation:
First, write the expression and distribute.
-2(2x+11)=5x+14
-4x-22=5x+14
Add one of the variables to the other side (it makes solving a lot easier). I'll add 4x to both sides because it won't result in a negative x.
-4x-22=5x+14
<u>+4x +4x</u>
-22=9x+14
Now, subtract 14 on both sides.
-22=9x+14
<u>-14 -14</u>
-36=9x
Divide both sides by 9.
-36=9x
<u>/9 /9</u>
-4=x or x=-4 (they both mean the same thing)
Have a wonderful day! I hope this helped :3
I guess its 3.5x (edited) .....

Step-by-step explanation:
<u>Radical Form and Exponent Form</u>
A radical can be expressed as a rational exponent following the identity:
![\displaystyle \sqrt[m]{x^n}=x^\frac{n}{m}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Csqrt%5Bm%5D%7Bx%5En%7D%3Dx%5E%5Cfrac%7Bn%7D%7Bm%7D)
We should also recall that:
We are given the expression:
