You already have $75. The monitor costs a total of $400. You save $25 each week. Write an equation using w, to represent the number of weeks that you will have to save in order to purchase the monitor. Use your equation and solve algebraically. Explain your solution.

13 weeks

Step-by-step explanation:

25w + 75 = 400

25w = 400 - 75

25w = 325

25w/25 = 325/25

w = 13

It will take 13 weeks until you can buy the monitor

So if there is 13 weeks you re able to buy the monitor but if it's less than 13 weeks you are broke.(lol)

Step-by-step explanation:

already have $75

monitor costs a total of $400.

each week 25

400 -75 =325

325 divided by 25 =13

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

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
