What is the value of x in the diagram?

Ksenya-84 [330]

The red arrows mean the lines are parallel. Since all angles are equal, the larger triangle is similar to the smaller one. Then corresponding sides have the same ratio
(4x -2)/9 = (3x+2)/12
x(4/9 -3/12) = (2/12) +(2/9)
x = (7/18)/(7/36) = 2 . . . . . . . . . corresponding to the 3rd selection

7 times the number of cookies in the jar plus 5 more from the tray is 54. How many cookies are in the jar?

Digiron [165]

Answer:

The number of cookies in the jar is 7.

If we include the 5 cookies from the tray in the jar the total number of cookies would be 5 + 7 = 12

Step-by-step explanation:

Consider the number of cookies in the jar as 'x'. Hence the equation formed would be:-

7(x) + 5 = 54

7x + 5 = 54

7x = 54 - 5

7x = 49

x = $\frac{49}{7}$

x = 7

The number of cookies in the jar is 7.

If we include the 5 cookies from the tray in the jar the total number of cookies would be 5 + 7 = 12

Hope this helps.
