Write the formula to calculate how much dough is prepared in x hours.
spin [16.1K]

Answer: D(x) = 2kg/h*x

where x is the number of hours.

Step-by-step explanation:

The information that we have is:

in 5 hours, we can prepare 10kg of dough.

With this, we can find the rate per hour, to do this we find the quotient:

R = 10kg/5h = 2kh/h

This meeans that in one hour, we can make 2kg of dough.

Then, in x hours, we can make x times 2kg of dough, then the equation will be:

D(x) = 2kg/h*x

where x is the number of hours.

1).  The inequality says "height is 54 or more".
Any height that is less than 54 does NOT qualify.

2).  The sign says  "Maximum total weight 800 pounds".
Any weight that's 800 pounds or less is OK.

3).  Paula has scored 21, 25, and 15 points.
. . . . . they're NOT all greater than 21
. . . . . they ARE all 25 or less
. . . . . they ARE all less than 30
. . . . . they ARE all 10 or more .

4).  First, write down the number of cans that
each student collected, but arrange them in order.
Then check each choice.
A).  misses the highest 3 students completely
B).  includes everybody
C).  misses the lowest 3 students completely
D).  OK, but the first and last intervals aren't needed,
       because nobody's cans are in those intervals
