Len needs $135.75 for a television. how many weeks will it take her to save enough money to buy a television? equation: t = 25 + 8.25w

14 weeks

Step-by-step explanation:

t = 25 + 8.25w

Len  needs 135.75

135.75 =  25 + 8.25w

Subtract 25 from each side

135.75-25 = 25-25 + 8.25w

110.75 = 8.25w

Divide each side by 8.25

110.75/8.25 = 8.25w/8.25

13.42424 = w

Since we need at least 135.75, it will take Len a little more than 13 weeks, so it will take Len 14 weeks to have enough money

14 weeks

Step-by-step explanation:

It will take 14 weeks for Len to save enough money to buy a television.

t = 25 + 8.25w

135.75 =  25 + 8.25w

Hope this helps!

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
