Answer:
Step-by-step explanation:
y + 5 = 8(x - 0)
y + 5 = 8x - 0
y = 8x - 5
0.4(420) = 4(420)/10
(0.4 is essentially 4/10)
1680/10 = 168
There are 168 sixth graders
$45-$3
you would do this to take out the processing fee.
$42/ $6
this is because each shirt cost $6
the equation would be (45-3) / 6= 7]
your answer would be 7 shirts
As y varies directly with x, there is a proportionality constant. As x increases by that certain constant, y also increases. We equate:
y = kx
where k = proportionality constant.
Given the condition, y = 5 when x = 4, then we solve for k:
5 = k(4)
k = 5/4 or 1.25
When y = 8, then
8 = (5/4)(x)
x = 8/(5/4) = (8)(4/5) = 32/5 or 6.4 (ANSWER)
678.58 that is the surface area to this problem
