4. Wilfredo buys 2/5 pound of mixed nuts for $2.50. at this rate how many pounds of mixed nuts can he buy for $10

Wilfredo can buy 1 3/5 pounds of Mixed Nuts for $10

Step-by-step explanation:

2/5*4=8/5

$2.5*4=$10

8/5=1 3/5 pounds for $10

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
