0.6y + 0.02 = 0.3y - 0.4
Subtract 0.3y from both sides.
0.3y + 0.02 = -0.4
Subtract 0.02 from both sides.
0.3y = -0.42
Divide both sides by 0.3.
y = -1.4
Answer:
the distance between the penguins and the fish tanks is 81 ft
Step-by-step explanation:
Let A is the point of whales
Let B is the point of Sharks
Let D is the point of Dophines
Let P is the point of penguins
Let F is the point of Fish tank
From a look at the photo, we can find some special properties that:
AB//PF
In triangle ABD and DPF we have
- ∠BAD=∠PFD(Alternate angles)
- ∠ADB=∠PDF(Vertically opposite angles)
By AA rule, ABD and DPF are similar to each other
Therefore, using the similarity property, we have:
=
So the distance between the penguins and the fish tanks is 81 ft
Answer:
The combined cost of 1 pound of turkey and 1 pound of ham is $10.50
Step-by-step explanation:
Consider the provided information.
Let x represents the cost of turkey (per pound)
Let y represents the cost of ham (per pound)
4 pounds of turkey and 2 pounds of ham. She pays a total of 30$

The turkey costs 1.50$ less per pound than ham.
Substitute the value of x in 





Now substitute the value of x in
Hence, the cost of 1 pound of turkey is $4.50 and 1 pound of ham costs $6.00
.
Therefore the cost of 1 pound each is:
$4.50+$6=$10.50
The combined cost of 1 pound of turkey and 1 pound of ham is $10.50
