Answer: a
Step-by-step explanation:
We know that 75=5*5*3 so
5*5*3 times 5=125*3=375 then move the decimal place two places to the left (divide by 100) and get 3.75
or you could note that 0.75=3/4 so
3/4 times 5=
15/4
simplified=3 and 3/4

Answer:
k = 9.6
Step-by-step explanation:
When dealing with inverse variation, the two variables vary in opposite directions. This means that as the first variable increases, second variable decreases and as the first variable reduces,the second variable increases.
Y varies inversely with x.
So as y increases, x reduces and as y reduces, x increases.
We would proceed by introducing a constant of variation, k
y = k/x
From the information given,
The constant of variation = k
The value if x = 6.4
The value of y = 1.5
To find the value of k
y = k/x
k = yx = 1.5 × 6.4
k = 9.6
