Answer:

A jumbo burrito cost more than $3.00

Step-by-step explanation:

The correct question is

The Larsen Family bought 3 jumbo burritos and 2 regular burritos for $13.65. The Russo family bought 5 jumbo burritos and 2 regular burritos for $20.23. Does a jumbo burrito cost more than $3.00? Write and solve a system of equations to justify your answer

Let

x ---> the price of one jumbo burrito

y ---> the price of one regular burrito

we know that

The Larsen Family

$3x+2y=13.65$ ----> equation A

The Russo family

$5x+2y=20.23$ ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is (3.29,1.89)

see the attached figure

The cost of a jumbo burrito is $3.29

therefore

A jumbo burrito cost more than $3.00

Which ordered pair is not a solution to this system?

spayn [35]

Answer:

A (2,1)

$x + y > 3 \\ x + 2y > 5 \\ \\ a)2 + 1 > 3 \: wrong \\ 2 + 2(1) > 5 \: wrong \\ \\$

So, right off the bat, you can tell that the ordered pair (2,1) is most definitely NOT the solution to this system.

Traveling at 65 miles/hour, how many feet can you travel in 22 minutes?

alexdok [17]

This is what's called a unit rate problem.

someone is going at 65 miles per hour, and you must find the distance in feet in 22 minutes. I think I know what chart you're talking about. I'm going to try to write it here, I don't know if it will appear the way I want it to

65 miles | 1 hour | 5280 feet | ----------------------------------------------- hour | 60 minutes| Mile| Now multiply the fraction out. Anytime a unit appears on both the top and bottom, it cancels, so miles and yours cancel. You end up with 343200 feet/ 60 minutes (all I did was multiply 65 by 5280 and add the remaining units and the denominator. The easiest way to get to your final answer is get the number of feet in one minute, so divide 343200 by 60 and you get 5720 feet/ min. To get the final answer, all you now have to do is multiply by 22 minutes to get 125840 feet.

Find the value of each variable and the measure of each labeled angle.

labwork [276]

Answer:

see explanation

Step-by-step explanation:

(8x - 75) and (5x) are vertically opposite angles and are congruent , then

8x - 75 = 5x ( subtract 5x from both sides )

3x - 75 = 0 ( add 75 to both sides )

3x = 75 ( divide both sides by 3 )

x = 25

Then

5x = 5(25) = 125°

8x - 75 = 8(25) - 75 = 200 - 75 = 125°

An integer is chosen at random from first hundred natural numbers. The probability that the integer chosen the multiple of 5 is

Ede4ka [16]

Answer: 0.2

Step-by-step explanation:

The first hundred natural numbers are 1 to 100.

Now, the numbers that are multiples of 5 are the numbers that end in 5 or 0, so we have:

5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100

So in the range, we have 20 multiples of 5.

Now, when we select at random, each number has the same probability of being selected, then the probability of randomly selecting a multiple of 5 is equal to the number of multiples of 5 divided the total number of options in the set.

we have 20 multiples of 5, and in the set we have a total of 100 numbers, then the probability is:

P = 20/100 = 0.2
