Vrite and simplify an expression to find he total cost of x pencils , 1 poster board , and (x + 1) notebooks.

The expression to find the total cost of x pencils, 1 poster board, and (x + 1) notebooks will be:

Step-by-step explanation:

Consider '' be the number of pencils which were bought

Consider ''  denotes the cost of pencil

Consider ''  denotes the cost of poster board

Consider '' be the number of notbooks which were bought

Consider ''  denotes the cost of notebook

As we have to find the total cost. Let 'C' denotes the total cost

so the expression becomes

simplifying

Therefore, the expression to find the total cost of x pencils, 1 poster board, and (x + 1) notebooks will be:

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.

-3

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
