14 trout out of 50 total fish. The total amount of fish in the lake is 7500. Let’s make this into a proportion.
14/50=x/7500
x represents how much trout is in the lake, we don’t know yet, but we’ll find out.
First, cross multiply.
14*7500=105000
50*x=50x
Now let’s turn this into an equation.
50x=105000
Divide both sides by 50
50x/50=x
105000/50=2100
x=2100
Out of the 7500 fish in the lake, 2100 were trouts.
Answer:
a₁ = -5, d = 7, a₂ = 2, a₃ = 9, a₄ = 16
equation of sequence: 
Step-by-step explanation:
a₁ + a₂ + a₃ = 6
a₁ + a₁ + d + a₁ + 2d = 6
3a₁ + 3d = 6
a₁ + d= 2 ⇒ a₁ = 2 - d
a₄ = 16
a₁ + 3d = 16
2 - r + 3d = 16
2d = 14
d = 7
a₁ = 2-7 = -5
a₁ = -5, d = 7 ⇒ a₂ = -5+7 = 2, a₃ = 2+7 = 9, a₄ = 9+7 = 16

Answer:p=69
Step-by-step explanation:
Let's solve your equation step-by-step.
3666=39(p+25)
Step 1: Simplify both sides of the equation.
3666=39(p+25)
3666=(39)(p)+(39)(25)(Distribute)
3666=39p+975
Step 2: Flip the equation.
39p+975=3666
Step 3: Subtract 975 from both sides.
39p+975−975=3666−975
39p=2691
Step 4: Divide both sides by 39.
39p
/39 = 2691
/39
Upward motion
