The percent increase from 8 to 14 equal to the percent decrease from 35 to x. what is the value of x
zhenek [66]

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

Find the values of x and y in the triangle below.<br> (Please hurry)
NikAS [45]

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
