Answer:
p = - 11x
q = - 6y + 3
r = 3z
s = - 15x + y
t = 2x - 14z - 11
u = 9y + 3x - 14
Step-by-step explanation:
Let, 7x + p + 3 - 9 = - 4x - 6
⇒ p = - 4x - 6 - 7x + 9 - 3
⇒ p = - 11x (Answer)
Let, - 19y + q + 15 = - 25y + 18
⇒ q = - 25y + 19y + 18 - 15
⇒ q = - 6y + 3 (Answer)
Let, - 7z + r - z + 14 = - 5z + 14
⇒ r = - 5z + 7z + z = 3z (Answer)
Let, 4x - 11y + s = - 11x - 10y
⇒ s = - 11x - 4x - 10y + 11y
⇒ s = - 15x + y (Answer)
Let, - 25x + z + t = - 23x - 13z - 11
⇒ t = - 23x + 25x - 13z - z - 11
⇒ t = 2x - 14z - 11 (Answer)
Let, 7y + u - 18 = 16y + 3x - 32
⇒ u = 16y - 7y + 3x - 32 + 18
⇒ u = 9y + 3x - 14 (Answer)
Answer:
76 balls and 24 bats
Step-by-step explanation:
Set up a system of equations where x is the number of balls and y is the number of bats:
x + y = 100
4.5x + 20y = 822
Solve by elimination by multiplying the top equation by -20, then combine the equations together:
-20x - 20y = -2000
4.5x + 20y = 822
-15.5x = -1178
x = 76
Then, plug in 76 as x in the first equation to solve for y:
x + y = 100
76 + y = 100
y = 24
So, 76 balls and 24 bats were purchased.
Answer:
CFB
Step-by-step explanation:
Answer: x =8
Step-by-step explanation:
-12 + 9x = 60 (the other angles are 60, 180 - (60 + 60) = 60)
9x = 72
x = 8
When you put it all together you should get P=9H
