Answer:
x=16/3
Step-by-step explanation:
left part : -1+3x-8
right part: 7
left part = right part
-1+3x-8=7
left part +8= right part +8
-1 + 3x -8 +8=7+8
-1+3x=15
left part : -1+3x
right part : 15
left part+1=right part+1
-1+3x+1=15+1
3x=16
so
x=16/3
Y = kx
the question ask for "direct vation"...the formula must always to be y at the left side and k at the right side
Answer:
21
Step-by-step explanation:
1/5 * 35 = 7
7*3 = 21
D is the correct equation for this problem.
Y directly proportional to WX and inversely to Z.
Y=k(WX)/Z
Where k is the constant of proportionality.
So, the first thing is to find the value of this constant.
k = YZ/WX
= (32×3)/(6×20)
= 96/120
= 0.8
The <span>equation that models the relationship will be;
Y = 0.8(WX/Z)</span>
