What is 10- 6 1/2? long way
Answer:
3 1/2
Step-by-step explanation:
10-6 1/2
20/2 -6 1/2
20/2- 13/2= 7/2
7/2= 3 1/2
Answer:
[tex]\frac{20}{2\\} \\[/tex] - [tex]\frac{13}{2}[/tex] = [tex]\frac{7}{2}[/tex] or 3[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
make the denominator the same.
so
10*2= 10 so
[tex]\frac{20}{2\\} \\[/tex]
then 6*2= 12+1= 13 so
[tex]\frac{13}{2}[/tex]
20-13= 7
so now
[tex]\frac{7}{2}[/tex] which is equal to 3[tex]\frac{1}{2}[/tex]

Alfonso runs 10 km at an average speed of x km/h.

Write down an equation in x and show that it simplifies to x? – 5x – 20 = 0.
Step-by-step explanation:
Note that t = d/r where t is time, d is distance, and r is rate/speed.
We can come up with two equations with the information given and the equation:
t_1 hr = (10 km)/(x km/hr)
t_2 hr = (12 km)/(x - 1 km/hr)
where t_1 is the time taken to run the 10km the first day and t_2 is the time taken to run the 12km the second day.
We know that 30 minutes is 1/2 of an hour and that t_1 is 30 minutes less than t_2 (as stated in the question). Therefore, we can write:
t_1 = t_2 - 1/2
Substituting the values we derived:
(10 km)/(x km/hr) = (12 km)/(x - 1 km/hr) -1/2
Then we can evaluate by multiplying by 2x(x-1) on both sides:
20(x-1) = 24x - (x)(x-1)
20x - 20 = 24x - x^2 + x
x^2 -5x -20 = 0
And we are done.
I hope this helps! :)
An equation is formed when two equal expressions. The equation for the time can be written as (12/x-1)-(10/x)=0.5. The value of x is 7.623.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
A.) Given Alfonso runs 10 km at an average speed of x km/h. Therefore, the time taken by Alfonso to rum 10km is 10/x hour.
Also, The next day he runs 12 km at an average speed of (x - 1) km/h. Therefore, the time taken by Alsonso to run 12km is 12/(x-1) hour.
Now, the time taken for the 10km run in 30minutes(0.5 hours) is less than the time taken for the 12 km run. Therefore, we can write,
[tex]\dfrac{12}{(x-1)}-\dfrac{10}{x} =0.5[/tex]
The equation for the time can be written as (12/x-1)-(10/x)=0.5.
B.) The value of x can be written as,
[tex]\dfrac{12}{(x-1)}-\dfrac{10}{x} =0.5\\\\12x-10(x-1)=0.5 \times x \times (x-1)\\\\12x - 10x +10 = 0.5x^2-0.5x\\\\2x+10 = 0.5x^2-0.5x\\\\0=0.5x^2 - 2.5x -10\\\\x = -2.623, 7.623[/tex]
Since the time can not be negative. Hence, the value of x is 7.623.

Write an equation of the line that pass through the given point and is (a) parallel and (b) perpendicular to the given line.
Answer:
Step-by-step explanation:
Here we need to write the equations that passes through the point (4 , 3) and is parallel to the given line and perpendicular to it. So lets get started,
a)
First we calculate the slope of the given line by using any two points on the given line by the help of the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
we take the points (1 , 6) and (2 , 2) i chose these two you can choose any other two doesn't matter so now we calculate the slope,
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-6}{2-1}\\\\m=\frac{-4}{1}\\\\m=-4[/tex]
now since our slope is -4 and the line is parallel to the given line so the line that we need in part a would also have the same slope by the law parallel lines have same slope/gradient.
[tex]m_1=m_2[/tex]
so the slope/gradient of our new line that we need which passes through the point (4,3) is -4
Now using the point slope form formula:
[tex]y-y_1=m(x-x_1)[/tex]
we have our point (4,3) which corresponds to [tex](x_1,y_1)[/tex] and m which corresponds to -4 , so now
[tex]y-y_1=m(x-x_1)\\y-3=-4(x-4)\\y-3=-4x+16\\y=-4x+19[/tex]
sow our new line in part a is
[tex]y=-4x+19[/tex]
b)
In this part we need a line that is perpendicular to the given line which means we use the formula to calculate the slope of the perpendicular line which is:
[tex]m_1m_2=-1[/tex]
where [tex]m_1=-4[/tex] the slope of our given line so the slope of the perpendicular line is,
[tex]m_1m_2=-1\\-4m_2=-1\\\\m_2=\frac{1}{4}[/tex]
so using the point (4,3) and the new slope 1/4 we find the equation of the perpendicular line again by using the point-slope form formula:
[tex]y-y_1=m(x-x_1)\\y-3=\frac{1}{4}(x-4)\\\\4y-12=x-4 \\4y=x+8\\\\y=\frac{x+8}{4}\\\\y=\frac{x}{4}+2[/tex]

Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. She scored a total of 24 baskets for both games. How many baskets did Mia score last Saturday?
Based on the information presented, it can be inferred that Mia made 8 baskets last Saturday.
How to calculate how many baskets Mia made last Saturday?To calculate the number of baskets Mia made last Saturday we must take into account the following information:
Yesterday she made 24 baskets.Last Saturday she made 3 times fewer baskets than yesterday.To calculate the number of baskets Mia made, we must divide 24 by 3 to find the number of baskets she made last Saturday.
24 ÷ 3 = 8So, it can be inferred that Mia made 8 baskets last Saturday.

If joe travels 37 miles in 30 minutes, how far can he travel in 4 hours?
Answer:
296 miles
Step-by-step explanation:
4 hours=240 minutes
240/30=8
37*8=296
Answer:
Joe travels 296 miles in 4 hours.
Step-by-step explanation:
How many minutes in an hour? 60.
How many minutes in 4 hours then? 60 * 4 = 240 minutes
Now take 240 minutes and divide it by 30. You get 8, this is what you need to multiply 37 by.
37 * 8 = 296.
Therefore, Joe travels 296 miles in 4 hours.
