baby Dino = 15 paintings
Adult Dino = 7 paintings
Entire herd = 208 paintings
//Defining of Variables:
A = no. Of Adult
B = no. Of Baby
This is a simultaneous question so we’ll have to make up some equations.
3B = A —— (1)
This means there is 3x as many baby Dino as adult Dino
15B + 7A = 208 —— (2)
This means 15 paintings being painted by B number of babies + 7 paintings being painted by A number of Adults is 208 paintings.
Those are the equations we set.
Since we know A = 3B,
We can substitute A = 3B into (2).
As such:
15B + 7A = 208
15B + 7(3B) = 208
15B + 21B = 208
36B = 208.
We did that so that we only have 1 unknown variable so that we can calculate what is the value of a unknown variable, which in this case, is B.
If we furthur solve that equation above,
36B = 208
B = 5.777777777 ????
The reason why I was left with 5.77777777 amount of baby dinosaurs is because I didn’t know the value of the variables correctly as you didn’t state it clearly.
However, I’ve done the concept behind this question and I hope it helps you :)
If you would like me to solve it, could you please give me the values of the variables clearly?
Thanks, and have a good day ahead!
The worth of Sarah's investment when she is 68 is $14,728.51.
<h3>What is the worth of the investment?</h3>
The formula that can be used to determine the worth of the investment is:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years = 68 - 18 = 50
$500 x (1.07)^50 = $14,728.51

The answer is bc cause you multiply 12 x 2= 24
Answer:
x = 5
Step-by-step explanation:
1. Distributive Property
(Do what's in the parenthesis first)
4x - 2x + 6 = -4 + 5x - 5
2. Combine Like Terms
2x + 6 = -9 + 5x
3. Take away 6 on both sides
2x + 6 - 6 = -9 - 6 +5x
It will give u.....
2x = -15 + 5x
4. Subtract 5x on both sides
2x - 5x = -15
It will give u.....
-3x = -15
5. Divide by -3 on both sides to isolate the variable
-3x / 3 = -15/-3
Now you get....
x = 5
2 negatives make a positive
Thats ur answer
Hope this helped!
Answer:
Step-by-step explanation:
