Answer:
you would need 12 rooms
Step-by-step explanation:
168/12=11.2 so you would have 11 full rooms and then a room for the leftover two
Answer:
11.2 or just 11
Step-by-step explanation:
Okay, so, I apologize if this is an idiot answer, but if you take your 168 hikers and divide them by each room which can hold 15 hikers, you'll get 11.2. NOW MAYBE THE .2 OF THE HIKERS CAN SLEEP ON THE FLOOR I DON'T KNOW SORRY IF THIS IS A TERRIBLE ANSWER.

Solve each equation and prove that your answer solves the original equation.
25 - 3x = 40 1/3x - 12 = -3
Answer:
25 - 3x = 40 x=-5
1/3x - 12 = -3 x=27
Step-by-step explanation:
25-3x=40 -> subtract 25 each side .... -3x=15 -> divide -3 each side...... x= -5

X/-2=-7 evaluate and show work
Answer:
10x.............
Step-by-step explanation:
or x=10
Answer:
x = 14
Step-by-step explanation:
Okay so the equation looks like this:
X/-2 = -7
In order for us to get rid of the -2 we are going to have to multiply -2 on both sides of the equal sign, so that we only have x on one side of the equal sign and numbers on the other:
X/-2 = -7
*-2 *-2
since multiplying or dividing a negative number by a negative number gives you a positive -7 is going to become 14 and x remains on the other side of the equal sign:
x = 14
Now to check our work we are going to place 14 where the x variable is in the equation:
X/-2 = -7 or (14)/-2 = -7
-7 = -7
Hope this helps you!!

Which equations can be represented by the line that contains the points (6. 8) and (2. 6)?
Answer:
y=1/2x+5
Step-by-step explanation:
first you have to find the slope by using [tex]\frac{y2-y1}{x2-x1}[/tex]
so when you plot in your points and you will get 1/2x.
then you need to find your y-intercept
and since you don't have a 0 you have to slove by using y=mx+b (slope-intercept) formula
you plug in your points and you will get
b=5 and that is how you get your equation.

A bus completed its journey of 320km with an average speed of 40 km per hours . How long does the bus takes to complete the journey if its average speed is increased to 56 km per hours ?
plzzz I need answer fast !!
Answer:
5.7 hours
Step-by-step explanation:
average speed = distance / time
rewriting gives
time = distance / average speed.
distance = 320 km
average speed = 56 km/hour
so
time = 320 / 56 = 5.7 hours

What is the solution for the system of equations? y=−x+4 y= x−2
Answer:
(3, 1 )
Step-by-step explanation:
Given the 2 equations
y = - x + 4 → (1)
y = x - 2 → (2)
Substitute y = x - 2 into (1)
x - 2 = - x + 4 ( add x to both sides )
2x - 2 = 4 ( add 2 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (2)
y = 3 - 2 = 1
solution is (3, 1 )

Tickets to a band concert cost $10 each. The equation y = 10x represents total cost, y, of x tickets. Which graph shows ordered pairs represented by this equation?
Answer:
the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.
The correct graph is attached below.
Step-by-step explanation:
Given the function equation
y = 10xGiven that the cost of each ticket is $10.
It means:
at x = 0, y = 10(0) = 0 ∵ cost of 0 ticket
at x = 1, y = 10(1) = 10 ∵ cost of 1 ticket
at x = 2, y = 10(2) = 20 ∵ cost of 2 tickets
at x = 3, y = 10(3) = 30 ∵ cost of 3 tickets
at x = 4, y = 10(4) = 40 ∵ cost of 4 tickets
at x = 5, y = 10(5) = 50 ∵ cost of 5 tickets
Now, observe the ordered pairs points on the right-hand graph of the first diagram.
This graph has the following ordered pairs:
(0, 0) i.e. at x = 0, y = 10(0) = 0(1, 10) i.e. at x = 1, y = 10(1) = 10 (2, 20) i.e. at x = 2, y = 10(2) = 20 (3, 30) i.e. at x = 3, y = 10(3) = 30 (4, 40) i.e. at x = 4, y = 10(4) = 40 (5, 50) i.e. at x = 5, y = 10(5) = 50Thus, the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.
The correct graph is attached below.

if 7(p+3)= -28 then what does p equal
Answer:
p = -7
Step-by-step explanation:
7(p+3) = -28
now we times the inside of the parenthese by 7
7p+21 =-28
now we minus 21 on both sides
7p= -49
now divide
p = - 7
Answer:
-7
Step-by-step explanation:
7(p+3) = -28
Divide by 7
7(p+3) / 7 = -28 / 7
p+3 = -4
Subtract 3
p+3 (-3) = -4 (-3)
P = -7

Solve the system, use Substitution: x + y = 11, y = x + 5 *
4 points
(-2 , 3)
(3 , 8)
(7 , 4)
(6 , 5)
Answer:
Use the Substitution method to solve this system of equations:
.
x=-y-1
x-y=-11
.
Substitute -y-1 for x in the second equation. (We can make this move because the first equation tells us that whatever x is, it is equal to -y-1.)
.
x-y=-11
%28-y-1%29-y=-11
.
Simplify by combining like terms.
-2y-1=-11
-2y=-10
y=5
.
Substitute 5 for y in the first equation.
x=-y-1
x=-%285%29-1
