Answer:
x =7
Step-by-step explanation:
The direct variation equation is y = kx, where k is the constant of proportionality.
If y = 5.5 when x = 11, we can write 5.5 = 11k, which, when solved for k, yields k = 0.5.
Then the direct variation equation in this case is y = 0.5x.
If y = 3.5, what is x? y = 0.5x becomes 3.5 = 0.5x, yielding x = 7
x=7
y=mx
5.5=m×11
5.5÷11=m
m=1/2
3.5=1/2×x
3.5÷1/2=x
if union, U means plus,+
if intersect means minus, -
0.06944444444 as a fraction equals 6944444444/100000000000
