146/24=6.08333 buses are needed.
But this 0.08333 means that there are 2 students left as a remainder. The first 6 busses are full, and 2 students are remaining outside. We cant leave them there! So we need another bus, which gives a total of 7 buses

What is a positive solution of x squared -36=5x
miv72 [106K]
Answer : 9


Explanation:

{x}^{2}  - 36 = 5x


Subtracting -5x from both sides,

{x}^{2}  - 5x - 36 = 0

Soving this quadratic equation by midterm split method,

{x}^{2}  - 9x + 4x - 36 = 0 \\  \\ x(x  - 9) + 4(x - 9) = 0 \\ (x - 9)(x + 4) = 0


So the roots here will be, +9 and -4.

Since the question is about only the positive value.
Your answer will be 9.

alicia got 60 questions correct on her science test. if she received a score of 75% how many questions were on the test?
Tomtit [17]
If we know that she got 75%, we can write it as the fraction 75/100.
We also know that she got 60 correct out of an unknown number of questions, which we can call 'x'
We means we know that 75/100 = 60/x (the number of questions)
Cross multiply to get an equation.
75 * x=60 * 100 -----> 75x=6000
Divide both sides by 75 to solve for x.
6000/75=80
x=80, meaning that her test had 80 questions on it.

What is the experimental probability of rolling a 3 or 4?
ohaa [14]

If it's 3 or 4 the probability is:

2/6 or 1/3

We call the outcomes in an event its "favorable outcomes". If a die is rolled once, determine the probability of rolling a 4: Rolling a 4 is an event with 1 favorable outcome (a roll of 4) and the total number of possible outcomes is 6 (a roll of 1, 2, 3, 4, 5, or 6). Thus, the probability of rolling a 4 is .

Six more than the product of seven and a number is 55.
mariarad [96]

Answer:

7x + 6 = 55; x=7

"product of seven and a number" -> 7x

7x + 6 = 55
