Mashcka [7]
I would use the starting position, sea level as zero. Then I would convert all those minutes to hours so the answer is an integer and not a decimal.
60 min * (-10 ft / 212 min) = -2.83 ft/hr

round to integer = -3 ft/hr

If A divided by B = 10 remainder of 6 what is b
elixir [45]

Answer:

B = (A - 6) / 10

Step-by-step explanation:

This problem has 2 variables and 1 equation so it is not trivial to solve with confidence the value of B; however, we can solve for B in terms of A.  With that being said, let's start.

If A divided by B = 10:

A/B = 10

10 remainder of 6

Could also be written as 10 & 6/B since B is the divisor.  Rewrite this, you can get the equation:

A/B = (10B + 6) / B

A = 10B + 6

A - 6 = 10B

B = (A - 6) / 10

Thus, you have solve B in terms of A.

Cheers.

Tamiku [17]

Given:

The inequality is

-10+8x

To find:

The missing step in solving the given inequality.

Solution:

Step 1: The given equation.

-10+8x

Step 2: Subtract 8x from both sides.

-10+8x-8x

-10

Step 3: Add 4 on both sides.

-10+4

-6

Step 4: Divide both sides by -2 and change the sign of inequity as we divide the inequality by a negative number.

\dfrac{-6}{-2}>\dfrac{-2x}{-2}

3>x

Therefore, the missing step is 3>x.
