The correct answer to this problem is the third statement which is "Alexia completed 20 math problems and 10 science problem". The following conditions are stated in the problem:
Alexia can answer 3 minutes on each math problem
Alexia can answer 4 minutes on each science problem
She worked more than 60 minutes
We have the inequality 3x + 4y > 60 where x represents the total number of math problem while y represents the total number of the science problem.
in our answer, we have x=20and y=10
3*20 + 4*10 > 60
60 + 40 > 60
100 > 60
Therefore, our answer is correct.
Answer:
f(12) = 11
Step-by-step explanation:
To solve this question:
- Substitute x = 12 into the equation: f(12) = 3/4 (12) + 2
- Simplify: 3/4 × 12 = 36/4 which is 9 → f(12) = 9 + 2
Hope this helps!
Answer:
You will need 5 quarts of paint to cover 300 square paint
Step-by-step explanation:
Adult tickets = 10
Child tickets = 4
10 + 4 = 45
Adult = 9
9*10 = 90
Child = 5
5*4 = 20
90 + 20 = 110.
Hope this helped☺☺
(I had this question once in my homework)
If the exponent, n, is a 2, then there will be 2 solutions. Always. The number of solutions to a polynomial is equal to the highest degree in the polynomial. So if n is 2, then and only then will you have 2 solutions.
