THESE ARE SEPARATE QUESTIONS THAT I DECIDED TO COMBINE:

saul85 [17]

1). Her walking pace is (1.75 miles) / (50 minutes).

If you want it in units of (miles per hour), do it like this:

   (1.75 miles / 50 minutes) x (60 minutes / 1 hour)

   = ( 1.75 x 60 / 50 ) miles per hour.

2). The average change was

   (30 - 45) degrees / (5 minutes) .

I'm sure you can do the division and make an integer out of that.

3). Each bracelet cost $3.10.
Caroline bought five of them, so she spent $3.10 five times.
Either do the multiplication, or else write down $3.10 five times
and do the addition.

4). In order to factor the expression, the two terms would need
to have some common factor ... both terms need either a power
of 'x', or they need two numbers that have a common factor.
They don't both have an 'x', and 13 and 10 have no common factor.

5). Todd earned 'T' dollars.
Twice what Todd earned is 2T .
$350 more than that is 2T+350 .
The question says that 2,500 is exactly that amount,
so you can write
      2T + 350 = 2,500

Subtract 350 from each side:    2T    = 2,150

Divide each side by 2: (you can finish it now)

A pizza company charges $8 for a large pizza and a $5 delivery charge. Write an equation that gives the

cupoosta [38]

8p +5 = $29
The above is the equation

If you want to know how many pizza were ordered then you subtract 5 from each side of the equal sign then you would have 8p=24 then divide by 8 on both sides of equal sign . p= 3 ; so 3 pizzas were order plus a charge of $5 for delivery.

If there's 15 players total 1/3 are wearing red shoes 2/5 or wearing blue shoes and everyone else is wearing black shoes what is

Volgvan

Answer:

$\frac{4}{15}$ is the fraction of people wearing with black shoes.

Step-by-step explanation:

Given:

If there's 15 players total, 1/3 are wearing red shoes, 2/5 are wearing blue shoes and everyone else is wearing black shoes.

Now, to find the fraction of people with black shoes.

Total players = 15.

Fraction of people wearing red shoes = $\frac{1}{3}.$

So, number of people are wearing red shoes:

$\frac{1}{3} \times 15\\\\=5.$

Fraction of people wearing blue shoes = $\frac{2}{5} .$

Thus, number of people wearing blue shoes:

$\frac{2}{5} \times 15\\\\=6.$

And rest are wearing black shoes.

Now, to get the number of people wearing black shoes by subtracting number of people are wearing red shoes and blue shoes from the total number of players:

$15-5-6\\\\=15-11\\\\=4.$
