noon. Of the students who do not mow lawns, 70% sleep until noon. Complete the two-way table.

20 students mow on Saturday, 3 of those sleep until noon. Those who don’t mow the lawns, 21 of them sleep until noon.

Step-by-step explanation: 40% of 50 is 20. 25% of 20 is 3. 50-20=30. 70% of 30 is 21

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
