Answer:
the total cost is $67
Step-by-step explanation:
9 × 3 = 27 8 × 5 = 40 40 + 27 = $67
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>
C, bc you add up all x’s, which give you 4x. Then you add 0.5,1,1.5 together, which is 3.
Answer:
5/8
Step-by-step explanation:
→ Work out how many red
8 - ( 2 + 1 + 2 ) = 3
→ Add up red and purple
3 + 2 = 5
→ Divide over total number of beads
5/8
