Tad and his buddies drove to the orange bowl(while going) -50mph
Tad and his buddies while returning from a trip -75mph
Total round trip = 12 hours
Distance while going = 50 x t
Distance while returning = 75 (12 - t)
50t = 75(12 -t)
50t = 900 -75t
50t + 75t = 900
125t = 900
t = 900/125
t= 7.2
The total number of hours it takes Tad and his buddies to drive to the orange bowl is 7.2 hours.

3u = 72 simplified math problem
Answer:
Simplifying
3u = 72
Solving
3u = 72
Solving for variable 'u'.
Move all terms containing u to the left, all other terms to the right.
Divide each side by '3'.
u = 24
Simplifying
u = 24
3u= 72
three will go to the other side so it will divide
and it well be
u= 24

Is (6, –2) a solution to this system of equations? y = –1/6 x − 1 y = 1/6 x − 3
Answer:
Yes, (6, -2) is a solution to the given system of equations.
Step-by-step explanation:
Please write y = –1/6 x − 1 y = 1/6 x − 3 as follows, for greater clarity:
y = (–1/6)x − 1
y = (1/6)x − 3
Let's actually solve this system:
y = (–1/6)x − 1
y = (1/6)x − 3
-----------------------
2y = -4, or y = -2
Now find x. Arbitrarily we choose to use the first equation for this purpose:
y = (-1/6)x - 1. We set y = -2 and find x: -2 = (-1/6)x - 1
Combining the constants, we get -1 = (-1/6)x, or 6 = x
Yes, (6, -2) is a solution to the given system of equations.
What are the solutions of the system? y = -6x – 6 y = x2 – 5x – 6
Answer:
Answer is 0
Step-by-step explanation:
-6x-6=x²-5x-6
-6(x+1)=(x+1)(x-6)
-6=x-6
x=0

Solve 3(x - 2) < 18
Hi there!
[tex]\large\boxed{x < 8}[/tex]
3(x - 2) < 18
Begin by dividing both sides by 3:
3(x - 2)/3 < 18/3
x - 2 < 6
Add 2 to both sides:
x - 2 + 2 < 6 + 2
x < 8
x< 8

A room needs to be painted. The room is 15 ft by 23 ft by 8 ft high. A gallon
of paint covers 250 2 and costs $28.
a. Find the number of gallons to paint the room.
b. What is the cost of painting the room if you do the work yourself?
Answer:
First we know that the room is a rectangular prism with measures:
width = W = 15ft
length = L = 23ft
height = H = 8ft
We want to paint the room (i suppose that we paint the four walls and the roof)
The area of each two of the walls the width times the height:
A = (15ft)*8ft = 120ft^2
And we have two of these walls, then the total area is:
area = 2*120ft^2 = 240ft^2
The area of each one of the other two walls is the height times the length:
A = (23ft)*8ft = 184ft^2
And we have two of these walls, then the total area is:
A = 2*184ft^2 = 368ft^2
The area of the roof is equal to the length times the width.
A = 23ft*15ft = 276ft^2
Then the total area we need to paint is:
area = 240ft^2 + 368ft^2 + 276ft^2 = 884 ft^2
a) We know that one gallon can cover 250 ft^2
Then to cover 884 ft^2 we need:
N = (884 ft^2)/(250 ft^2) = 3.536 gallons of paint
b) Knowing that each gallon costs $28, and that we need 3.536 gallons of paint to paint the room, the total cost is:
3.54*$28 = $99.008 = $99.01
Now if for some reason you only can buy paint in whole numbers, then you can not buy exactly 3.536 gallons, then you need to buy 4 gallons, and in this case, the total cost will be 4 times $28
cost = 4*$28 = $112

You randomly choose a marble from a jar. The jar contains 4 red marbles, 10 blue marbles, 7 green marbles, and 6 yellow marbles. Find the probability of the event. Not choosing a blue marble.
Answer:
17/27
Step-by-step explanation:
Since there are 10 blue marbles, and 27 total marbles, the probability of not choosing a blue marble is 17/27 because you subtract the amount of blue marbles (10) from the amount of total marbles (27).
The probability of not choosing a blue marble is 17/27.
What is probability?
Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Number of red marbles = 4
Number of blue marbles = 10
Number of green marbles = 7
Number of yellow marbles = 6
The event is the probability of not choosing a blue marble is
⇒ [tex]\frac{red+green+yellow}{Total marbles}[/tex]
⇒ [tex]\frac{4+7+6}{27}[/tex]
⇒ [tex]\frac{17}{27}[/tex]
Hence we can conclude that the the probability of not choosing a blue marble is 17/27.

Write an equation in point-slope form and slope-intercept form for each line
1. passes through (1, 9), slope = 2
2. passes through (4, -1), slope = -3
An equation of a line in point-slope form: y - y₁ = m(x - x₁)
1.
passes through (1, 9) ⇒ x₁ = 1, y₁ = 9
slope: m = 2
The equation:
y - 9 = 2(x - 1) ← point-slope form
y - 9 = 2x - 2 {add 9 to both sides}
y = 2x + 7 ← slope-intercept form
2.
passes through (4, -1) ⇒ x₁ = 4, y₁ = -1
slope: m = -3
The equation:
y + 1 = -3(x - 4) ← point-slope form
y + 1 = -3x + 12 {subtract 1 from both sides}
y = -3x + 11 ← slope-intercept form

three line segments have measures of 4 units, 6 units, and 8 units. Will the segments form a triangle?
Given:
Three line segments have measures of 4 units, 6 units, and 8 units.
To find:
Will the segments form a triangle?
Solution:
We know that three line segments can form a triangle if the sum of two smaller sides is greater than the largest side.
Three line segments have measures of 4 units, 6 units, and 8 units. Here, the measure of the largest sides is 8 units.
The sum of two smaller sides is
[tex]4+6=10[/tex]
[tex]4+6>8[/tex]
Since the sum of two smaller sides is greater than the largest side, therefore the segments will form a triangle.

Which equation is equivalent to 3 = 87 ÷ h? A. 3 = (87 ÷ h) – 9 B. 3 × 9 = (87 ÷ h) ÷ 9 C. 3 + 9 = (87 ÷ h) + 9 D. 3 – 9 = (87 ÷ h)
Answer:
3= (87÷h)
Step-by-step explanation:
The question is to pick among the option the solutions that will be equal to 3= (87÷h)
Therefore the most suitable and correct option is
3×9= (87÷h)÷9
27= (87÷h)÷9
Divide by 9
3= (87÷h)
Hence the answer is 3=(87÷h)

Joe's lunch at a restaurant cost $18.00 without tax he leaves the server a tip of 14% of the cost of lunch without tax what is the total cost of lunch including tip without tax
Ok. So 14% of 18.00 can be figured out without a calculator. 18.00 / 10 = 1.80 = 10%.
(18.00 / 100) x 4 = 0.72
1.80 + 0.72 = $2.52 is the tip.
$18 + $2.52 = $20.52
