X + 12 = 20
x + 12 -12 = 20 -12
x = 8
Answer:
Linear
Step-by-step explanation:
9/10 - 5/10
because the denominators are the same you keep it and just subtract the numerators
=4/10
This can be reduced to 2/5
93 x 2 = 186
x = 186 - 112
x = 74
y = 2(80) - 74
y = 160 -74
y = 86
360 - 112 - 74 - 86 = 88
z = (88+86)/2
z = 87
