You and a friend go to tacos for lunch. You order two burritos and five tacos and your total bill is $16. Your friend's bill is $15 for three burritos and three tacos. How much does a burrito cost? How much does a taco cost?

Answers

Answer:

Burrito = $3

Taco = $2

Step-by-step explanation:

Let b represent the cost of burrito

Let t represent the cost of taco

2b + 5t= 16.......equation 1

3b + 3t = 15.......equation 2

Multiply equation 1 by 3 and equation 2 by 2

6b + 15t= 48

6b + 6t = 30

9t= 18

t = 18/9

t = 2

Substitute 2 for t in equation 1

2b + 5t= 16

2b +5(2) = 16

2b + 10= 16

2b = 16-10

2b = 6

b = 6/2

b= 3

Hence the price of burritos is $3 and the price of taco is $2

Fill in the table using this function rule y = 4 + 5x

Answers

Step-by-step explanation:

bruh ,come on this was so easy

The value of y using this function rule y = 4 + 5x is 19,29,34 and 49.

We are given that;

The function y=4+5x

Now,

To fill in the table using the function rule y = 4 + 5x,

we need to substitute each value of x into the rule and calculate, the corresponding value of y. For example, when x = 3, we get:

y = 4 + 5x

y = 4 + 5(3)

y = 4 + 15

y = 19

We can repeat this process for the other values of x and fill in the table as follows:

| x | y |

| 3 | 19|

| 5 | 29|

| 6 | 34|

| 9 | 49|

Therefore, by the function answer will be 19,29,34 and 49.

A department store sells a pair of shoes with an 87% markup. If the store-bought the pair of shoes for $55.25, what is the selling price to the nearest dollar?

Answers

Answer: $103
Explanation:
Stores will markup an item to make a profit so this question is asking how much they will be selling the shoes to the customer.
To solve this problem we will start by multiplying the price the store payed for (55.25) by the percentage in decimal form (.87)
55.25•0.87=48.0675

We then add the markup to the price payed for the shoes.
55.25+48.0675=103.3175

When rounding to the nearest dollar we look at the digit in the tens place (3) and since 3 is < 5 we round the final price to $103

The probability can be obtained using several methods :

Using a standard normal distribution table ;

P(Z < 0.37) = obtain the value at the intersection where 0.3 is on the vertical axis and 0.07 on the horizontal axis of the Z distribution table

At the flag shop, for every 13 stripes there are 50 stars. If there are 10,000 stars, how many more stars are there than stripes?

Answers

Answer: 7,400

Step-by-step explanation:

First, we need the values of stars and stripes. So, let's start with the 50 stars. If there are 10,000 stars, we need to divide 10,000 by 50 to see how many sets of the 13 stripes th ÷ere are.

10,000 ÷ 50 = 200 sets of stripes.

We know that each set of stripes has 13 stripes, and there are 50 sets.

We will now multiply 13 with 20, to finf the total number of stripes:

13 x 200 = 2,600 stripes.

But WAIT! We aren't done yet!

We need to subtract 2,600 from 10,000 so that we can find how many more stars are there than stripes.

10,000-2,600 is 7,400
