Mr. Lockhart is digging a trench to put in the new school sprinkler system. Every 1/4 hour,
the length of his trench increases by 2/3 foot. By how much does the length, in feet, of
Mr. Lockhart's trench increase each hour?

ft. (2.67 ft.)

Step-by-step explanation:

We know that every 1/4th of an hour, the trench increases by 2/3 of a foot. To find how large the trench is in an hour, we simply multiply 2/3 by 4.

If we want to find the value without being in a fraction, divide 8 by 3.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

may i see the picture? it would a lot, xox
