A)5x = 122+3
5x = 125
x = 125/5
x = 25
B) 3x = 81-3
3x = 78
x = 78/3
x = 26
Answer:
- 1, - 3, - 5
Step-by-step explanation:
Substitute n = 1, 2, 3 into the rule, that is
a₁ = - 2(1) + 1 = - 2 + 1 = - 1
a₂ = - 2(2) + 1 = - 4 + 1 = - 3
a₃ = - 2(3) + 1 = - 6 + 1 = - 5
Answer:
I guess the answer is (-2.5x-8=y)
Answer:
b = 55°
c = 35°
Step-by-step explanation:
b° = 180° - (85°+40°) = 180° - 125° = 55°
c° = 180° - (b°+90°) = 180° - (55°+90°) = 180° - 145° = 35°
