Answer:

x = 350

Step-by-step explanation:

x - starting amount

\frac{2}{7} x  = after transport

\frac{1}{5} (\frac{2}{7} x) = after sweets

\frac{1}{5} (\frac{2}{7} x) = 20

(\frac{2}{35} x) = 20

2x = 700

x = 350

ludmilkaskok [199]

Answer:

44.044%

Step-by-step explanation:

To find the answer we first have to find the value of each percent, to do this we divide 100 by 350, that gets us approximately 0.286. We know that he won 154 of them we then multiply 154 by 0.286 to get the percentage of games he won and we get 44.044.

Point V lies between points U and W on line UW. The distance between U and V is 2x-4, and the distance between V and W is 4x+10.
gogolik [260]

Answer:

36UNITS

Step-by-step explanation:

If point V lies between U and W, then UV+VW = UW

given parameters

UV = 2x-4

VW = 4x+10

UW = 9x-9

Substituting the given functions in the formula first, we will have;

2x-4+4x+10 = 9x-9

6x+6 = 9x-9

Collect like terms

6x-9x = -9-6

-3x = -15

x = -15/-3

x = 5

Substitute x = 5 into UW.

Since UW = 9x-9

UW = 9(5)-9

UW = 45-9

UW = 36
