Answer:
40/3
Step-by-step explanation:
w = weight of soil needed
f = number of flower beds
a = constant value
w = a * f
<em>substitute</em>
10 = 6a
<em>simplify</em>
5/3 = a
w = (5/3)f
<em>plug in 8</em>
w = (5/3)(8)
<em>simplify</em>
w = 40/3
Step-by-step explanation:
Y= x - 2. Y = 3x + 5
Putting value of y
x - 2 = 3x + 5
-2 - 5 = 3x - x
-7 = 2x
-7/2 = x
Putting value of x
Y = 3(-7/2) + 5
Y = - 10.5 + 5
Y = - 5.5
3/(5x) + x = 3/(5x) + x/1 * (5x)/(5x)
= 3/(5x) + 5x²/5x
= (3+5x²) / 5x
