W=kxp
where
k is the constant of proportionality given by:
k=w/xp
<span> If w=78 when x=2 and p=10 then
</span>k=78/(2*10)
k=3.9
thus the formula is:
w=3.9xp
b] <span>find x when w=858 and p=5.5
plugging the values in the formula we get:
858=3.9</span>×5.5×x
hence
x=858/(3.9×5.5)
x=358/21.45
x=16.69
<span>(6ab</span>³<span>c)(-abc</span>²<span>) = -6a</span>²b⁴c³
<h3><u>The value of the unknown number is equal to 1.</u></h3>
6(x + 2) = 20x - 2
Distributive property.
6x + 12 = 20x - 2
Subtract 6x from both sides.
12 = 14x - 2
Add 2 to both sides.
14 = 14x
Divide both sides by 14.
x = 1
the denominator would be 12
Gonna go with D.i think u just have to add all the miles
