= -35 + 7 - 15
= -43

Answer:
B. m∠B = 80°
Step-by-step explanation:
Supplementary angles are two angles that sum to 180°
⇒ m∠A + m∠B = 180°
⇒ 100° + m∠B = 180°
⇒ m∠B = 180° - 100°
⇒ m∠B = 80°
Answer:
2/3
Step-by-step explanation:
32(4x – 1) – 3x = 54 –(x + 2)
⇒ 32×4x-32-3x= 54-x-2 (using the distributive property)
⇒ 128x-32-3x=54-x-2
Taking terms on x on one side and constant term on other, we get
128x-3x+x= 54-2+32
⇒ 126x= 84
⇒ x= 84/126
⇒ x= 2/3
ik this might not make sense but hope this helps
Step-by-step explanation:
-2/3f =9.2
cross multiply
27,6= -2f
divide both sides by 2
f = - 13.8
-1/8n = -2/7
cross multiply
-16 = -7n
divide
n = 2.29
12/20n = -36/44
cross multiply
528 = - 720n
divide
n= -0.733
-64.5g = -25.8
divide both sides by -64.5
g = -0.4
the last one has no variable
