Answer:
X=5
y=3
Step-by-step explanation:
you’re welcome
Answer:
x = 5y = 3Solution:
=> x + 4y = 17-x - 6y = -23
=> -2y = -6=> y = 3Now, let's substitute the value of y into the first equation.
x + 4y = 17=> x + 4(3) = 17=> x + 12 = 17=> x = 5Let's check our answer to make sure it is correct.
Check:
-x - 6y = -23=> -(5) - 6(3) = -23=> -5 - 18 = -23=> -23 = -23Hence, this is proven correct.
Hoped this helped.

Find the slope of the line that passes through (7,5) and (5, 4).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answers
Answer:
y = 1/2x + 3/2
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
m = (4 - 5)/(5 - 7)
m = (-1)/(-2)
m = 1/2
Slope-intercept: y = mx + b
y = 1/2x + b
using (5,4)
4 = 1/2(5) + b
4 = 5/2 + b
b = 4 - 5/2 = 8/2 - 5/2 = 3/2
then y = 1/2x + 3/2

A community organization sponsored a trip to a baseball game, offering bleacher seats for $20 and grandstand seats for $30. The organization sold $2600 worth of seating and 100 people attended the game. How many tickets did they sell for each type of seat?
Answers
The number of bleacher seat is 40 and grandstand seats is 60
Data Given;
bleacher seat = $20grandstand seat = $30total amount generated = $2600total number of people in attendance = 100To solve this problem, we have to write a system of equation.
Let x represent the number of bleacher seat
let y represent the number of grandstand seat
[tex]x + y = 100... equation (i)\\20x + 30y = 2600... equation (ii)[/tex]
From equation (i)
x + y = 100
x = 100 - y ... equation (iii)
Put equation (iii) into equation (ii)
[tex]20x + 30y = 2600\\\\x = 100 - y\\20(100 - y) + 30y = 2600\\2000 - 20y + 30y = 2600\\2000 + 10y = 2600\\10y = 2600 - 2000\\10y = 600\\10y/10 = 600/10\\y = 60[/tex]
Since we know the value of y, let substitute it into equation i and solve for x
[tex]x + y = 100\\x = 100 - y\\x = 100 - 60\\x = 40[/tex]
From the calculations above, the number of bleacher seats is 40 and the grandstand seats is 60

Answers
Answer:
Hamid: 4
Ken: 3
Step-by-step explanation:
Start by finding the LCM (least common multiple) of 80 and 60. To do this we can list all the multiples of 80 and 60 until we get a common multiple.
60: 60, 120, 180, 240
80: 80, 160, 240
They both have a common multiple of 240, so after 240 seconds they will meet again at the start line.
Now we need to find how many laps they'll have to run. To do this we can divide 240 by the amount of time it takes for them to run a lap.
240/60=4
240/80=3
Hamid will have ran 4 laps and Ken will have ran 3 laps
