Helpp!! :Edith babysits for x hours a week after school at a job that pays $4 an hour. She has accepted a job that pays $7 an hour as a library assistantworking y hours a week. She will work both jobs. She is able to work no more than 16 hours a week, due to school commitments. Edith wants to earn at least $80 a week, working a combination of both jobs.
write an inequality to represent this,and please solve for y

Answers

so pay=hours times pay per hour

so the babysitting job pays 4 dollers pay per hour
she works x hours
therefor the babysitting pay is 4 times x or 4x

the library job pays 7 dollars an hour
she works y hurs
therefor the library pay is 7 times y or 7y


so total pay is babysitting pay plus library pay or
4x+7y=total pay
x+y=total hours

she wants to work no more than 16 hour s aweek, means that she can work max 16 hours or
total hours<16
subsitute
x+y<16

and she wants to earn at least 80 dolars
so more than or equal to 80 dolllars
total pay >80
subsitue
4x+7y>80


so the inequalities we have are
x+y<16 and
4x+7y>80

solve for y since we want to do that
multiply the first equatl by -4
remember tha tmultipy by negative means flip sign from < to > so
-4x-4y>-64
now add to the second equation

-4x-4y>-64
4x+7y>80 +
0x+3y>16
3y>16
divide by 3
y>16/3
16/3=5 and 1/3

so she has to work more than 5 and 1/3 hours per week

basically, she will earn at least 80 dollars a week if she works at least 5 and 1/3 hours at the library and works for 16 hours total (library+babysitting)

what you should do is find the graph of the lines
x+y<16 and 4x+7y>80 and find where they intersect




the inequaltiy is 4x+7y>80 and x+y<16
4x plus 7y, this shows how much she works....

1. Find x, the missing
side length in the right
triangle.
36
77

Answers

Answer:

x=41

Step-by-step explanation:

Final answer:

To find the missing side length in a right triangle, use the Pythagorean theorem. In this case, the missing side length is approximately 74.92.

Explanation:

To find the missing side length in a right triangle, you can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, we have one side length given as 36 and another side length given as 77. Let's label the missing side length as 'x'. Using the Pythagorean theorem, we can write the equation:

x^2 = 77^2 - 36^2

Solving this equation, we get x ≈ 74.92 (rounded to two decimal places).
