Proulem-solving Vecision: Reasonable Answers
Problem for English class. Jennifer needs to read a series of
books. She decides to read 15 pages each day. She multiplied
by 14 to find how many pages she will read in 2 weeks
1. What was Jennifer trying to find by multiplying 15 x 147
15
X 14
60
15
75
2. Did Jennifer use the correct information and the correct
operation? Explain.
3. Is the answer reasonable? Why or why not? If not, give the
correct answer
Problem The teacher assigned the class to read 25 pages a
week. Marcus multiplied to find the number of pages the students
will read in a year
25 X 12 - 300 pages
4. Did Marcus use the correct information and the correct
operation? Explain.
5. Is the answer reasonable? Why or why not? If not, give the
correct answer.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

5 + 8 +7 + 4 + 0 +1 = 25

step-by-step explanation:
