Lisa was assigned 64 pages to read for english. She has finished 3/4 of the assignment. How much more is she supposed to read?

16 ?

Step-by-step explanation:

64 divided in 4 ?

16 pages

Step-by-step explanation:

64 / 4 = 16.

16 x 3 = 48.

64 - 48 = 16.

Lisa already read 48 pages, she needs to read 16 more.

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

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
