4.5w = 5.1w -30
4.5w - 5.1w = 5.1w - 5.1w -30 (subtracted 5.1w on both sides)
4.5w - 5.1w = -30 (next combine like terms)
-0.6w = -30 (next do the inverse operation of w)
w = -30 ÷ -0.6
w = 50 (it became positive cause minus and minus = positive)
so your final answer is: w = 50
Hope that helps:D
It is c I think I'm not positive but Ive done this one
Answer:
1.15
Step-by-step explanation:
tan θ=−4/7, and 270°<θ<360°
θ is in 4th quadrant
sec θ = 8.06 / 7 = 1.15
Use Pythagorus theorem:
a²+b²=c²
(12)²+(16)²=c²
400=c²
√400=c
20=c
Therefore, the hypotenuse would be 20 ft.
Hope I helped :)
