Answer:
C) 2.6
Work Shown:
a = x, b = 3, c = 4
a^2 + b^2 = c^2 ... pythagorean theorem
x^2 + (3)^2 = (4)^2
x^2 + 9 = 16
x^2 = 16 - 9
x^2 = 7
x = sqrt(7)
x = 2.64575131106459
x = 2.6
There are two types of tickets sold at the Canadian Formula One Grand Prix race. The price of 5 grandstand tickets and 3 general admission tickets is 2490. The price of 6 grandstand tickets and 6 general admission tickets is 3540 . What is the price of each type of ticket?
Answer: Grandstand: 360, General Admission: 230
Step-by-step explanation:
Use any variable you like but:
Let g represent grandstand ticketsLet a represent general admission ticketsYou know:
5 Grandstand tickets and 3 general admission tickets is 2490:
5g + 3a = 2490The price of 6 grandstand (g) tickets and 6 general admission tickets (a) is 3540
6g + 6a = 3540You want to find out: What is the price of each ticket. To do this either use substitution or elimination.
I will demonstrate elimination:
To do elimination, you want to cancel out one variable. This means you want to multiply each side of the equation by a number. I see 3a and 6a. This means multiply by -2. Again, you want to eliminate the variable.
5g +3a = 2490 → -10g - 6a = -4980Now, add the two equations together: Notice how you can line them up vertically to see how they can add together.
-10g - 6a = -4980+6g + 6a = 3540After that step you get: -4g = -1440Now you can solve for the g (grandstand tickets):
-4g = -1440g = 360You now know grand stand tickets cost 360. Take one of your original equations and solve for a (general admission tickets). To double check your work, they should satisfy both equations.
5g + 3a = 24905(360) + 3a = 24903a = 690a = 2306g +6a = 35406(360) +6a = 35406a = 1380a = 230Therefore general admission tickets cost 230, and grandstand tickets cost 360!

Solve the equation 7(w + 13) = 35.
I know that it is:
7w + 20 = 35
- 20 - 20
7w/7 = 15/7
But I just don't know what 15 divided by 7 is as a fraction. Some one please help this is due in a week!
Answer:
w = -8
Step-by-step explanation:
7(w + 13) = 35
Divide each side by 7
7/7(w + 13) = 35/7
w+13 = 5
Subtract 13 from each side
w+13-13 =5-13
w = -8
Or you can distribute
7w +91 = 35
Subtract 91 from each side
7w+91-91 = 35-91
7w = -56
Divide each side by 7
7w/7 = -56/7
w = -8
Answer:
7(w+13)=35 {Here, 7 is wholly multiplied to w and 13}
7w+91=35
7w=35-91= -56
w= [tex]\frac{-56}{7}[/tex]
w= -8
Proof:
7(-8+13)= -56+91= 35
Therefore, w= -8
Solve the equation -8(n + 7) = -88. What are two ways to start solving this equation? Choose BOTH ways.
1) Subtract 7 from both sides.
2) Use the distributive property.
3) Add 8 to both sides.
4) Add 88 to both sides.
5) Divide both sides by -8.
Answer:
Divide each side by -8
Distribute
Step-by-step explanation:
-8(n + 7) = -88.
Method 1
Divide each side by -8
n+7 = 11
Subtract 7 from each side
n = 4
Method 2
Distribute
-8n-56= -88
Add 56 to each side
-8n = -32
Divide by -8
n=4
Answer:
Distributive property & dividing -8 on both sides.
Step-by-step explanation:
You can begin solving the equation by either using the distributive property or dividing -8 on both sides.
Distributive Property:
[tex]-8(n+7)=-88\\-8n-56=-88\\-8n=-32\\n=4[/tex]
Dividing:
[tex]-8(n+7)=-88\\n+7=11\\n=4[/tex]

Answer:
Blank1: (-1/10)
Blank2: 1
Blank3: 5
Step-by-step explanation:
First we can see that numerator is equal to 1 in the last equation, so the second missing value is 1. Looking at the middle equation we can differ that the denominator is 10. This means the missing number in the third equation is equal to ten, so a*2=10, where the answer "a" is the missing value. Solve the equation by dividing both sides by 2 leaving a=5. Final step is to make 1/5+b=1/10, where ''b" is the answer for the first blank. Solve the equation by subtracting (1/5) from (1/10) leaving b=(-1/10)

A law in Washington, D.C., restricts a new building's height to no more than 20 feet taller than the width of the street it faces. You design a building with stories that are each 15 feet tall for a street that is 88 2/3 feet wide. What is the greatest number of stories your building can have?
_______ Stories
How much shorter is your building than the height restriction?
________Feet
It can be up to 20 feet taller so add 20
To the width:
88 2/3 + 20 = 108 2/3
Divide total height by the height of one story:
108 2/3 / 15 = 7.24
The building can have 7 stories.
b. 7 x 15 = 105 total feet
108 2/3 -105 = 3 2/3 feet below the restrictions

Explanation: try Desmos. its a magical machine
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 6) and (x₂, y₂ ) = (- 1, 4)
m = [tex]\frac{4-6}{-1-5}[/tex] = [tex]\frac{-2}{-6}[/tex] = [tex]\frac{1}{3}[/tex] , then
y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 4 ) , then
4 = - [tex]\frac{1}{3}[/tex] + c ⇒ c = [tex]\frac{12}{3}[/tex] + [tex]\frac{1}{3}[/tex] = [tex]\frac{13}{3}[/tex]
y = [tex]\frac{1}{3}[/tex] x + [tex]\frac{13}{3}[/tex] ← equation of line
-----------------------------------------------------------------------
The equation of a line in point- slope form is
y - b = m(x - a)
m is the slope and (a, b) a point on the line
Here m = 3 and (a, b) = (- 2, 0 ) , then
y - 0 = 3(x - (- 2) ) , that is
y = 3(x + 2)
y = 3x + 6 ← equation of line

Graph the line that represents a proportional relationship between ddd and ttt with the property that an increase of 3 units in ttt corresponds to an increase of 8 units in ddd.
What is the unit rate of change of ddd with respect to ttt? (That is, a change of 1 unit in t will correspond to a change of how many units in d?)
The unit rate of change of d with respect to t is 8/3
How to graph the line?The statement is given as:
increase of 3 units in t corresponds to an increase of 8 units in d.
This can be represented using the following ratio
t : d = 3 : 8
Express as fraction
t/d = 3/8
See attachment for the graph of t/d = 3/8
The unit rateIn (a), we have:
t/d = 3/8
Inverse both sides
d/t = 8/3
This means that:
Slope or Rate = 8/3
Hence, the unit rate of change of d with respect to t is 8/3

Andrew and Michael are 15 miles apart. If they walk towards each other, they meet in 3
hours. If they both walk in the same direction, Michael overtakes, Andrew in 8 hours.
How fast does each boy walk?
Answer:
75 miles miles an hour. (First one)
5 mph for the second one.
Step by Step:
1800%2F3 = u + v (1) is the equation for the flight with the wind.
(Here "u" is the airspeed of the airplane with NO wind,
"v" is the wind speed)
1800%2F4 = u - v (2) is the equation for the flight against the wind.
Simplify equations (1) and (2) and write them as a system:
u + v = 600, (1')
u - v = 450. (2')
Now add the two equations (1') and (2'). You will get
2u = 1050 ---> u = 1050%2F2 = 525 miles per hour.
Having this, you can easily determine "v" from (1'):
v = 600 - 525 = 75 miles per hour.
