Eddie had 20 dollars to spend on 3 gifts. he spent 11 9 10 dollars on gift a and 4 3 5 dollars on gift b. how much money did he have left for gift c?

Step-by-step explanation:

Total amount of money that Eddie had to spend was $20. The total number of gifts is 3 labelled as gift A, gift B and gift C.

He spent 11 9/10 dollars on gift A. Converting 11 9/10 dollars to improper fraction, it becomes 119/10 dollars.

He also spent 4 3/5 dollars on gift B. Converting 4 3/5 dollars to improper fraction, it becomes 23/5 dollars.

Total amount of money spent on gift A and gift B would be

119/10/+ 23/5 = (119 + 46)/10 = 165/10

= $16.5

The amount that he has left for gift C would be 20 - 16.5 = $3.5

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
