Edith bought a science book and a math book for her college classes. The cost s, in dollars, of the science book is $28.75 more than the cost m, in dollars, of the math book. Write an equation that relates the prices of the two books.

do m= 28.75 minus S

or do s= 28.75 minus m

Step-by-step explanation:

do m= 28.75 minus S

or do s= 28.75 minus mdo m= 28.75 minus S

or do s= 28.75 minus mdo m= 28.75 minus S

or do s= 28.75 minus mdo m= 28.75 minus S

or do s= 28.75 minus mdo m= 28.75 minus S

or do s= 28.75 minus mdo m= 28.75 minus S

or do s= 28.75 minus mdo m= 28.75 minus S

or do s= 28.75 minus mdo m= 28.75 minus S

or do s= 28.75 minus mdo m= 28.75 minus S

or do s= 28.75 minus m

s=28.75+m

Step-by-step explanation:

If s is the cost of the science book, and it is 28.75 dollars more than the math book, we need to add the 28.75 dollars to the cost of the math book in order to find out how much the science book costs. Another equation you can use is:

28.75=s-m

So, if you subtract the cost of the math book from the amount of the science book, you will get 28.75.

Hope this helps and Good Luck!

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
