65 + (3x-10) + 2x = 180
65 +5x-10 = 180
55 + 5x =180
5x = 125
x = 125/5 = 25
x = 25
B = 3(25)-10 = 75-10 = 65
C = 2(25) = 50
For landing on heads the fraction is 1/2 which is 50%
Answer:
C
Step-by-step explanation:
divide 14 by 4 to solve it, you get 3.5 or 3 1/2
Answer:
0,-2,-8,-36
Step-by-step explanation:
Answer:
x = 3
y = 0
z = 8
Step-by-step explanation:
a) 3x + 3y - z = 1
b) z = 8
c) -x -3y + 2z = 13
a) 3x + 3y - 8 = 1 (substitution)
a) 3x + 3y = 9
c) - x - 3y + 2(8) = 13 (substitution)
c) -x - 3y + 16 = 13
c) -x - 3y = -3
(3x + 3y = 9) + (-x -3y = -3)
= 2x = 6
x = 3
a) 3(3) + 3y - 8 = 1
9 + 3y - 8 = 1
y = (1 -9 + 8)/3
y = 0
