x+(x+1)+(x+2)+(x+3)=-210
x+1x+1+1x+2+1x+3=-210
4x+6=-210
4x=-210-6
4x/4x=-216/4
x=54
Answer:
67667.7
Step-by-step explanation:
let the number= Y
the question simply means that 0.15 percent of Y which give 10.5
so, let find Y:
0.15% of Y 10.15
<h3>Stating the mathematical equation</h3>
0.15/100×y = 10.15
0.0015y= 10.15
divide bothsides by 0.0015
0.0015y/0.0015= 10.15/0.0015
y=6766.66
y= 6766.7 approximately
<h3>therefore, 0.15% of 6766.7 is 10.5</h3>
