Answer:
B
Step-by-step explanation:
Make a proportion.
x is the number of balloons sold each day.

Answer:
x= 20 and the decreased value is 35-20=15
Step-by-step explanation:
percent increase = 6/14*100= 43
Percent decrease = 35-x/35*100
6/14*100=35-x/35*100
6/14= 35-x/35
6* 35= 14(35-x)
210= 490-14x
14x= 490-210
14x= 280
x= 280/14= 20
Answer:
x = 10.4
y = 9
Step-by-step explanation:
Suppose the triangles are similar
x/26 = 8/20 (side lengths must be proportional) cross multiply expressions
20x = 208 divide both sides by 20
x = 10.4
same goes for y
6/(6+y) = 8/20 cross multiply expressions
120 = 8y + 48 subtract 48 from both sides
72 = 8y divide both sides by 8
9 = y
All of them are wrong its 91 but if you want click or circle 90
