If we add $0.14 until we get $21.64, we would add it 154.572 times. To check this answer and make sure I’m right, do this equation: 0.14 x 154.572, then you would get 21.64.

The correct answer is 154.572 minutes.

Bus A leaves the station every 30 mins bus b leaves the station every 20 mins at 10 am both buses leave the station together wor
denis-greek [22]

Answer: 11am

Step-by-step explanation:

To solve this, we have to calculate the lowest common multiple of 20 and 30. This will be:

20 = 20, 40, 60, 80, 100

30 = 30, 60, 90, 120, 150.

Here, the lowest common multiple is 60.

Therefore, we add 60 minutes to 10am. This will be:

= 10am + 1 hour

= 11 am

The next time that both buses leave at the same time would be 11am

Solve the equation with quadratic formula<br> y^2+3y-10=0
neonofarm [45]

Answer:

y = 2 and y = -5

Step-by-step explanation:

Because the coefficient is not greater than 1, you can simply solve the problem without the quadratic formula.

By using the "x" method, you must figure out what multiplies to give you -10, and adds to give you 3

So, you find your values as 5 and -2. You then set these values equal to zero in terms of Y. As so---- (y+5)=0 and (y-2)=0

Then, you solve out to get your answer! Y is equal to -5 and 2
