To get the result we have to transform given formula into y=ax+b form.
Lets do this
5x+3y=6 /-5x (subtract 5x both sides)
3y=-5x+6 /:3 (divide both sides by 3)
y=

In form y=ax+b we know that a is slope and b is y intersect. We can read from our transformed equation that slope a=

and its the result
Answer:
≈ 18 cm
Step-by-step explanation:
1. Find the length of half a circle of radius 3.5 cm:

2. Find the length of the diameter:
D = 2r = 2 · 3.5 = 7 cm
3. Find the perimeter of the figure:
P = 10.99 + 7 = 17.99 ≈ 18 cm
:} Im sorry i dont know
...........................................................
Sin(a+b)=sin(a)cos(b)+cos(a)sin(b).
Let a=42 and b=17 so sin(42+17)=sin59.
Change 5/8 and 3/10 so they have the same denominator
5/8×5/5=25/40
3/10×4/4=12/40
25/40+12/40=37/40
5/8+3/10=37/40
