Sally collects stamps. Of all her stamps, 45% are from the United States. She has
90 stamps from the United States. How
many total stamps does she have?

90 stamps are .45 of her collection
90/.45=x/1.00
cross-multiply
.45x=90
x=200 stamps, dividing both sides by 0.45

+.45x+=+90+
+x+=+90%2F.45+
+x+=+200+
She has 200 stamps

So 200 stamps she has

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
