Answer:
Step-by-step explanation:
1)4.5m+4.7=20m+47
4.5m-20m=47-4.7
-15.5m=42.2
m=-2.72
2)14+21w=7(2+3w)
41+21w=14+21w
21w-21w=14-41
3)49r+35=7(7r+35)
49r+35=49r+245
49r-49r=245-35
4)9(8h-3)=72h-27
72h-27=72h-27
72h-72h=-27+27
5)5.2+5.3t=10+15t
5.3t-15t=10-5.2
-9.7t=4.8
t=4.8/-9.7
t=0.49
6)6f+3.111=18f-33
6f-18f=-33-3.111
-12f=-36.111
f=-36.111/-12
f=3.01
Answer:
x =5.1
Step-by-step explanation:
For the angle 82, we know the adjacent side and the opposite side
tan 82 = opposite/ adjacent
tan 82 = 36/x
Multiply by x on each side
x tan 82 = 36/x*x
x tan 82 =36
Divide by tan 82
x tan 82/ tan 82 = 36 / tan 82
x = 36/ tan 82
x=5.059470049
To the nearest tenth
x =5.1
Slope = (4 - 0)/(0 - 8) = -1/2
b = 4
equation
y = 1/2(x) + 4
