The two stadiums with the largest capacities are Marshfield Stadium and Bowden Stadium. Marshfield Stadium has a capacity of 7,675 more than Bowden. If the combined capacity for the two stadiums is 210,355, find the capacity for each stadium.
Answer: Capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.
Step-by-step explanation:
Let x = Capacity of Marshfield Stadium.
y = Capacity of Bowden.
As per given, we have
x - y = 7,675 (i)
x+y = 210,355 (ii)
2x = 218030 (iii)
[tex]\Rightarrow\ x= \dfrac{218030}{2}\\\\\Rightarrow\ x= 109015[/tex]
Put value of x in (i) , we get
109015 - y = 7675
⇒ y= 109015 - 7675
⇒ y= 101,340
Hence, capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.

charges $4 for tickets and $3 per snack that is bought. What is the equation
of both theaters?
Ay2x + 4
y 3x+ 5
B. y = 4x + 2
y = 5x + 3
OC. y = 5x + 2
y 4x + 3
O D.y = 2x + 5
y = 3x + 4
Ed
Answer:
the answer is d.
Step-by-step explanation:
as soon as you go to the theater, you HAVE to pay $5 in theater a, with two dollars for ONE snack bought, and it says two dollars PER one snack bought. therefore if x was 2, so if someone wanted to buy 2 snacks, then you would multiply by 2 to get the total cost, or y, for the snacks. answer d is the only one that has the correct numbers in the correct places for theater a and b.

Answer:
Angle 3= 37 degrees, Angle 2 = 143 degrees, Angle 4= 143 degrees
Step-by-step explanation:
Angle 3 is across from Angle 1 so they are equal to each other. Now to find Angles 2 and 4, cover angles 2 and 3 with your hand so you are just looking at 1 and 4, they are on a line. Lines are 180 degrees, so since angle 1 we know is 37 degrees, then 180-37= 143 degrees for angle 4. Now, 2 and 4 are opposites of each other, and share the same value of 143 (just like how we found angles 1 and 3 to be equal bc they are across from each other)
12 (10x + 15) – 32 = 2x + 6 + 3x
Answer:

120x-148=5x+6
115x=154
x=154/115

Answer:
t ≤ 12/23
Step-by-step explanation:
-48t + 2 ≤ -71t + 14
You would need to get all the numbers on one side and all the variables on the other side.
-48t + 2 -2 ≤ -71t + 14 -2 → -48t ≤ -71t + 12
-48t + 71t ≤ -71t + 71t + 12 → 23t ≤ 12
23t ÷ 23 ≤ 12 ÷ 23 → t ≤ 12/23

Answer:
0
-20
-7
Step-by-step explanation:
0 x any number = 0
4(-5) = -20
126/(-18) = -7
Answer:
1. 0
2. -20
3. -7
Step-by-step explanation:
1. 0 times anything is equal to nothing times something.
So, the first one is 0.
2. For 4 x -5, you can just do 4 x 5 x -1, which equals 20 x -1, whixh equals -20.
3. Remember, a negative times a negative = a positive. So, the number must be negative. Just do 126 / 18 x -1, which equals -7.

What is the y-intercept of a line that passes through the points (5, -6.5) and (-12, 2)?
Answer:
y-intercept = -4
Step-by-step explanation:
equation of a line: y=mx+b
two points given are (5, -6.5) and (-12, 2)
first we can easily find value of m or the slope, by using the slope formula. the value of m=-0.5.
formua to find m: [tex]\frac{2-(-6.5)}{-12-5}[/tex]= -0.5
to find the value of b (the y-intercept), we need to plug in a y and x value, we are given 2 ordered pairs, you can use either one and plug x-value in for x and the y-value in for y.
if i plug in (5, -6.5), my equation looks like this: -6.5=5(-0.5)+b
then you just solve for b and it turns out to be -4.
The solution is -4
The y intercept of the line passing through the points
P ( 5 , -6.5 ) and Q ( -12 , 2 ) is -4
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P = P ( 5 , -6.5 )
Let the second point be Q = Q ( -12 , 2 )
Now , the slope of the line between 2 point is given by
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2 + 6.5 ) / ( -12 - 5 )
Slope m = - 8.5 / -17
Slope m = -1/2
Slope m = -0.5
Now , the equation of line is given as
y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - ( -6.5 ) = -0.5 ( x - 5 )
On simplifying the equation , we get
y + 6.5 = -0.5x + 2.5
Subtracting 6.5 on both sides of the equation , we get
y = -0.5x - 4
The equation is of the form y = mx + b where m is the slope and b is the y-intercept
Therefore , the y intercept of the line is -4
Hence , the y intercept of the line A is -4

Gail has $100 and wants to have her hair styled for the prom. The salon charges $56 for a hair styling. Gail plans to leave a 20% tip. In dollars, how much money will she have left after she pays the hair stylist?
Answer: She has left $32.8 after she pays the hair stylist.
Step-by-step explanation:
Money Gali has = $100
Charge per hair style = $56
Tip percent = 20%
Total charge for hair styling = Charge per hair style + Tip
= $ (56+ 20% of 56)
= $ (56+0.2 x 56)
= $ (56+11.2)
= $ 67.2
Money left = Money Gali has - Total charge for hair styling
= $ (100-67.2)
= $ 32.8
Hence, she has left $32.8 after she pays the hair stylist.
