Answer:
286
Step-by-step explanation:
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.
Answer: The brother drove 6 hours and the sister drove 5 hours of the trip
Step-by-step explanation:
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.

745 is the answer
basically,
775 - 15 l-2l (absolute value = positive number)
so
775 - 15 (2)
MULTIPLY -15 X 2 -----> -30
775 - 30
= 745
Can anyone help me with my work? Ill give credit to those who do. I'll just put my z00m contact below and add me so we can work on it, thanks!
Answer:
I mean i got class in 2 minutes bUT ILL TAKE THE POINTS THO
Step-by-step explanation:
Given f(x) and g(x) = f(k⋅x), use the graph to determine the value of k. Two lines labeled f of x and g of x. Line f of x passes through points negative 4, 0 and 0, 4. Line g of x passes through points negative 2, 0 and 0, 4. −2 negative one half one half 2
Answer:
k=2
Step-by-step explanation:
the equation of straight line passing through the two points (a , b) and (c , d) is
Now f(x) passes through (-4 , 0) and (0 , 4)
the equation is
y=x+4
Now g(x) passes through (-2 , 0) and (0 , 4)
the equation is
y=2x+4
here f(x)=x+4 and g(x)=2x+4
clearly g(x)=f(2x)
therefore k=2

Ralph and his brother are at a carnival. They separate from each other at the Ferris wheel at 1:00 PM, and they agree that they will each meet back at the Ferris wheel from time to time to see whether the other is ready to leave.

Answer:
3:00PM please mark me brainliest and thank me
Step-by-step explanation:
you have to find the lowest common multiple between 12 and 10 and that is 120 and 120 minutes is 2 hours. So 1:00 PM+ 2 hours= 3:00 PM
Answer:
2:00pm
Step-by-step explanation:
1pm separated
= 12 x 5 = 60 minutes
1+1hr = 2nd hr = 2:00pm

Which types of graphs are best used when representing individual data points rather than categories?
line graph
bar graph
line plot
stem-and-leaf plot
Links=reported
Answer:
Bar graphs to show numbers that are independent of each other.
Pie charts to show you how a whole is divided into different parts.
Line graphs show you how numbers have changed over time.
Cartesian graphs have numbers on both axes, which therefore allow you to show how changes in one thing affect another.Step-by-step explanation:
Answer:
Line Graph

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
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! :)

What is the slope of the line formed between point A and point B?
A. -2
B. -1/2
C. 1/2
D. 2

If you look closely, line AB is on the same line as DE.
Since these are on the same line, there is no change.
Therefor the answer is -1/2

Alana's hair grew 2 inches in 5 months, how many inches will her hair grow in 1 year?
Answer: 4
Step-by-step explanation:
First, get 2 and 5 together 2/5 ad than 1 year is 2 of the 5 months so that is 10 so your equation should look like 2/5 = i/10 then cross multiply 2x10=20 5xi = 5i now your equation looks like 5i = 20 divide 5 on both sides and your answer is i = 4.
