(2, 4) is the correct answer
Answer:
6/16 or 3/8 (simplified) is your answer.
Step-by-step explanation:
10 children <em>has</em> learned how to juggle 4 balls at a time. There are 16 in all. You are solving for the amount of children that <em>has not learned</em>.
Subtract: 16 - 10 = 6
Set the amount gotten over the total: 6/16
6/16 or 3/8 (simplified) is your answer.

Answer:
Multiply the first equation by 3 and multiply the second equation by -2.
This is justified by the multiplication property of equality
Step-by-step explanation:
we have
----> first equation
----> second equation
step 1
Multiple the first equation by 3 both sides
-----> by multiplication property of equality
----> new first equation
step 2
Multiple the second equation by -2 both sides
-----> by multiplication property of equality
----> new second equation
step 3
Solve the system of equations by elimination
Adds new first equation and new second equation
Find the value of x
substitute the value of y in any equation and solve for x
The solution is the point 
therefore
Multiply the first equation by 3 and multiply the second equation by -2.
This is justified by the multiplication property of equality
Answer:
The average interest rate will be approximately 9.64%
Step-by-step explanation:
Enrique borrowed $23000
2% interest on $4500 will be
4500 × 2/100
= 45 × 2
= $90
On the rest, which is
$23000 - $4500 = $18500
11.5% interest on $18500 will be
18500 × 11.5/100
= 185 × 11.5
= $2127.50
The total interest will be
$90 + 2127.50 = $2217.50
The average interest will be Total interest multiply by 100, divide by principal
That is Interest = pr/100, where t = 1
r = (I × 100)/p
r = (2217.50 × 100)/23000
r = 221750/23000
r ≈ 9.64%
