Need help with finding the x!!!

1 answer:

8 0

Angle QRT is supplementary to angle SRT, so they add up to 180, so angle SRT's measure is 180-9x

From there you can add up all three angles inside the triangle and set them equal to 180

so $(180-9x) +$ $(9+x)+5x=180$

Combine like terms and solve for x ⇒ x=3

Amanda spent $73 on shirts. Tee Shirts cost $9 and long sleeve shirts cost $11. IN she bought a total of 7, then how many of eac

pentagon [3]

Answer:

2 tee shirts

5 sleeves

Step-by-step explanation:

Let the number of shortsleeves be S and longsleeves L.

Total is 7

That is

L + S = 7

Total money spent is $73, while shorts cost 9 and longs 11

Hence,

9S + 11L = 73

We now have two equations we can solve simultaneously. From the first equation,

L = 7 - S

Putting this in equation 2

9s + 11(7 - S) = 73

9s + 77 - 11S = 73

2S = 4

S = 2

Since s = 2, then L = 5
