The triangles are similar. Set the two triangle's measurements equal to each other


8/10 = (x - 1)/(x + 2)


Cross multiply


8(x+ 2) = 10(x - 1)


Distribute the numbers


8(x) = 8x

8(2) = 16

10(x) = 10x

10(-1) = -10


8x + 16 = 10x - 10


Isolate the x. Subtract 16 from both sides, and 10x from both sides


8x (-10x) + 16 (-16) = 10x (-10x) - 10 (-16)


8x - 10x = -10 - 16


Simplify. Combine like terms


-2x = -26


Isolate the x. Divide -2 from both sides


-2x/-2 = -26/-2


x = -26/-2


x = 13


13 is your answer for x



hope this helps

enyata [817]

Answer:

The system of inequalities that represents this situation is:

x+y≥10

6x+4y≤50

Step-by-step explanation:

As the statement says that Laura wants to provide one party favor per person to at least 10 guests, the first inequality would indicate that the number of stuffed animals plus the number of toy trucks should be equal or greater than 10:

x+y≥10

Also, the statement indicates that miniature stuffed animals cost $6.00 each and the toy trucks cost $4.00 each and that Laura has $50. From this, you would have an inequality that indicates that 6 for the number of miniature stuffed animals and 4 for the number of toy trucks would be equal or less than 50:

6x+4y≤50

The answer is that the system of inequalities that represents this situation is:

x+y≥10

6x+4y≤50
