Answer:
74.30
Step-by-step explanation:
Let s = entry price for a student
Let t = entry price for a teacher
4s +5t = 95
6s+10t = 173
I will use elimination to solve this problem.
Multiply the first equation by -2
-2(4s +5t) = -2*95
Distribute
-8s - 10t = -190
Add this equation to the second equation to eliminate t
-8s - 10t = -190
6s+10t = 173
----------------------
-2s = -17
Divide by -2
-2s/-2 = -17/-2
s = 8.50
Now we need to find t
4s +5t = 95
Substitute s=8.50
4(8.50) +5(t) = 95
34 +5t = 95
Subtract 34 from each side
34-34 +5t = 95-34
5t = 61
Divide by 5
5t/5 = 61/5
t = 12.20
We want to find the cost for 3 students and 4 teachers
3s+4t
3(8.50) + 4(12.20)
25.50 + 48.80
74.30
Phillip would use 31 markers because you would divide 496 by 16 to see how many markers he would place. Your final answer would be 31 markers. Hope this helps you!
Answer:
Therefore the THREE roots are
Step-by-step explanation:
Given:
To Find:
All the Roots = ?
Solution:
As the degree of the polynomial is THREE then the number of root are also THREE.
Now one root is Zero For other we need to Factorize
So by Splitting the middle term
i.e Factor of 12 such that sum should be 7
i.e 3 × 4 = 12 and 3 + 4 = 7
∴ 
Therefore the THREE roots are
Answer: 1/4 cups of butter
Step-by-step explanation:
You need 1/2 cups of butter for every 2 eggs.
When a question asks for the unit rate, it means what quantity of the other variable is needed per 1 unit of the variable in question.
In other words, how many cups of butter are needed per egg.
= Cups of butter / no. of eggs
= 1/2 ÷ 2
= 1/4 cups of butter
