<span>5×(2-x)+9-7x
=5</span>×2-5<span>×x+9-7x
=10-5x+9-7x
=10+9-(5x+7x)
=19-12x
That's your solution. ^_^</span>
B dhs.3200
because 10% of 4000=400

Can I ask how did u make the picture? Plz tell me how
Answer:
x = 31.4
PQ = 58.8
Step-by-step explanation:
Set up a proportion:
SQ/QP = ST/PR
Substitute in the values they give you:



This means that PQ = 2x - 4 = 2(31.4) - 4 = 62.8-4 = 58.8
