Answer:
B) 12
Step-by-step explanation:
(9y + 7)° + (7y - 19)° = 180° (interior angles in the same side of transversal)
(9y + 7 + 7y - 19)° = 180°
(16y - 12)° = 180°
16y - 12 = 180
16y = 180 + 12
16y = 192
y = 192/16
y = 12
Answer: Exactly One Solution
Step-by-step explanation: All you have to do is evaluate the problem.
9z - 6 + 72 = 162 - 6
9z - 6 + 72 = 156
9z + 66 = 156
9z = 90
z = 10
Answer:
B. 3x+5y≤20y≥1
Step-by-step explanation:
3 hours for a cap
x = cap
5 hours mittens
y = mittens
this is the amount of time
3x+5y <=20
she must do a pair of mittens
y>=1
-2m+15=45
-2m=45-15
-2m=30
2m=-30
m=-15
