This means that W=P, X=Q, Y=R, and Z=S
9) W = P so P = 80°
10) QR = XY so QR = 3
11) WX = PQ so WX = 5
12) Z = S so Z = 35°
13) X = Q so X = 100°
14) R = Y so R = 145°
For the first one
x=-6
the second your answer is 2.92 hours

Answer:
7th week
Step-by-step explanation:
Let us represent the number of weeks as x
Jill begins the summer with $500 in her savings account. Each week, she withdraws $20.
$500 - $20× x
500 - 20x
Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week.
$150 + $30 × x
150 + 30x
At what week will both Jill and Sam have the same amount in their account?
We solve this be Equating both Equations together
Jill = Sam
500 - 20x = 150 + 30x
Collect like terms
500 - 150 = 30x + 20x
350 = 50x
Divide both sides by 50
50x/50 = 350/50
x = 7 weeks
Therefore, at the 7 week, Jill and sam would have the same amount in their accounts
