Answer:
3.75
Step-by-step explanation:
4x+9=24
4x=24-9
4x=15
x=15/4
x=3.75
100%/x%=148/43
<span>(100/x)*x=(148/43)*x - </span>we multiply both sides of the equation by x
<span>100=3.44186046512*x - </span>we divide both sides of the equation by (3.44186046512) to get x
<span>100/3.44186046512=x </span>
<span>29.0540540541=x </span>
<span>x=29.0540540541
</span>now we have:
<span>43 is 29.0540540541% of 148</span>
