9 rubber stamps cost $8.64 Which equation would help determine the cost of 88 rubber stamps?

Help me write "5x-(x-18)= " in those things. 5(-7) <---- (Something like that) X = -7

anzhelika [568]

Answer:

This how you get x. First the way to find the answer is to first put 5x by itself by canceling it out and putting it on the other side of the = which will be

5x-(x-18)=

-5x -5

Which then gets you this

-(x-18)=-5x

After that its

x-18=-5x

once you have this subtract x

x-18=-5x

-x -x

-18=-6x

Then it leaves you the easy part of just dividing

-18/-6x=-6x/-6x

After dividing you get x to be 3

x=3

Once you have x=3 input that number into your equation and you get the answer.

Hope this helps

Sako makes 11 cakes to share equally among 5 people. How many cakes does each person get?

Rudik [331]

Answer: 2 cakes and 2 slices of an extra ( assuming its cut into 10 slices)

Step-by-step explanation:

11 divided by 5 is equal to 2.2

in this case, 11 cakes divided by 5 friends is equal to 2 cakes and 2 slices.

normally you would just give them 2 cakes each (if you had 10 cakes) but you have 1 left over. So unless Sako wanted a cake as well, that's the answer(if she did, it would only be 2 cakes, no extra slices).

The circumference of an NBA-approved basketball is 29.6 in. Given that the radius of Earth is about 6400 km, how many basketball

ella [17]

Answer:

167,886,383 basketballs

Step-by-step explanation:

We are asked to find how many basketballs would take to circle around the equator. We have given the earth's radius. So, we need the formula to obtain it's perimeter. Thus:

$Perimeter = Pi*diameter [m]\\Where Pi = 3.14$

Earth's diameter is simply radius*2. It means:

$P= 3.14*6400*2 = 40,192 [km]$

On the other hand, we have a basketball crcumference; however, we need to obtain its diameter so that we can later calculate how many basketballs fit on earth's equator by simply dividing earth's circumference by a basketball's diameter.

Diameter of a basketball:

$D= Perimeter /Pi [m]$
