Driving Your brother and sister took turns driving on a 635-mile trip that took 11 hours to complete. Your brother drove at a constant speed of 60 miles per hour and your sister drove at a constant speed of 55 miles per hour. Let x be the number of miles your brother drove and let y be the number of miles your sister drove. Solve the linear system x + y = 11 and 60x + 55y = 635 to find the number of miles each of your siblings drove. Show your work.

Answers

Answer 1

Answer: The brother drove 6 hours and the sister drove 5 hours of the trip

Step-by-step explanation:

Driving Your Brother And Sister Took Turns Driving On A 635-mile Trip That Took 11 Hours To Complete.
Answer 2

Your brother drove 35 miles, and your sister drove 600 miles.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have the following system of equations:

x + y = 11                ....(i)

60x + 55y = 635  ....(ii)

Using the elimination method:

Multiply equation 1 by 55, equation 2 by -1, and add both equations together:

55x + 55y = 605, -60x - 55y = -635

Simplify and solve for x: -5x = -30

x = 6

Substitute this value of x back into equation 1 to find y:

y = 11 - 6 = 5

Thus, your brother drove 35 miles, and your sister drove 635 - 35 = 600 miles.

Answer:

  (47xy)/(6√3)

Step-by-step explanation:

A variable term is one that contains one or more variables, possibly with a coefficient. We can use 47xy as our variable term.

A constant is some number, or a representative of a particular number. π and e and Ф are representative of irrational constants. Of course, any number is also a constant. We can use 6√3 as our constant.

A quotient is formed when a first value is divided by a second value.

Here is the quotient of our variable term and our constant:

64.8=6(m+2.9)
what is m
please help me and explain how did you get your answer

Answers

Answer:

= −11.2

Step-by-step explanation:

64.8=6(m+22)

We move all terms to the left:

64.8-(6(m+22))=0

We calculate terms in parentheses: -(6(m+22)), so:

6(m+22)

We multiply parentheses

6m+132

Back to the equation:

-(6m+132)

We get rid of parentheses

-6m-132+64.8=0

We add all the numbers together, and all the variables

-6m-67.2=0

We move all terms containing m to the left, all other terms to the right

-6m=67.2

The answers is
M=7.9

You roll a six-sided number cube and flip a coin. What is the probability of rolling a number less than 2 and flipping heads? *
1/12
1/4
6/2
2/6

Answers

Answer:

1/12

Step-by-step explanation:

First, you should already be able to understand that the only number less than 2 on this cube is 1. So, you can understand that there is a 1/6 chance because there is a total of 6 numbers, and out of those, only 1 of those are your answer.

Then, you will note that a coin only has 2 sides, so there is a 50/50 chance of getting heads, or 50%. Now, you will turn that into a fraction, which is 1/2.

Next, you will multiply to make the denominators the same. And what you do to the denominator must happen to the numerator. (1/6 * 2--> 1/12 and 1/2 * 6 = 1/12)

Hope this helps! :)
