A shoemaker bought 30 pairs of heels. How many individual heels did the shoemaker buy?

1 answer:

7 0

<span>So we want to know how many individual heels did the shoemaker bought if he bought 30 pairs of heels. So to get to the answer we must know that one pair of heels is equal to two individual heels. So now we can calculate the individual number of heels: 30 pairs * 2 = 60 individual heels. </span>

In a test (+5) marks are given for every correct answer and (-2) marks are given for every incorrect answer. Smitha answered all

Ymorist [56]

Answer:

15 answers

Step-by-step explanation:

To solve this question we need to set up an equation.

Let's name the number of incorrect answers x.

<u>We can set up an equation that's essentially:</u>

(Points for correct answer)*(number of correct answers)+(points for incorrect answer)*(number of incorrect answers)=final score

When we plug in our numbers and variables it looks like this:

5(3)+(-2x)=-15

Simplify

15-2x=-15

Subtract 15 from both sides

-2x=-30

Divide both sides by -2

x=15

This means Smitha attempted 15 wrong answers, and that there were 18 questions in total.

Identify the horizontal

jonny [76]

Answer:

y=0

Step-by-step explanation:

Hello!

To solve this problem and find the asymptote you must find the value of x, for which F (x) (or y) becomes infinite, for this we solve the equation for X

$y=\frac{3}{5X} \\X=\frac{3}{5y}$

As you can see if Y takes a value of zero, then X would tend to be an infinitely large value so we conclude the horizontal asymptote is y = 0, I also attached the graph!

How do I solve -5 - (15y - 1) = 2 (7y - 16) - y

Aleks [24]

If you want to solve the equation -5 - (15 * y - 1) = 2 * (7 * y - 16) - y, you can calculate this using the following steps:

-5 - (15 * y - 1) = 2 * (7 * y - 16) - y
-5 - 15 * y + 1 = 14 * y - 32 - y
-5 + 1 + 32 = 14 * y - y + 15 * y
28 = 28 * y /28
y = 1

The result is 1.

At the local ball park, the team charges $5 for each ticket and expects to make $1,400 in concessions. The team must pay its pla

Eduardwww [97]

Answer:

The number of tickets must be sold is 2500

Step-by-step explanation:

The charge for each ticket = $ 5

The concessions amount = $ 1400

The amount paid to players = $ 2000

The amount paid to workers = $ 1600

The cost of each bag given to each fan = $ 3 per bag

Let The number of tickets sold = x

Now, number of ticket sold = number of fans = x

So, According to question

( charge per ticket × number of fans - cost of each bag × number of fan - concession amount ) = amount paid to players + amount paid to workers

Or, $5 x - $3 x - $1400 = $2000 + $1600

Or, $2 x = $3600 + $1400

Or, $2 x = $5000

∴ x = $\frac{5000}{2}$ = 2500

Hence Answer
