30 x 4 = 120 justina collection is 30 and shamea's is 120, 30 + 120 = 50
Answer:
30
Step-by-step explanation:
There's a proper way to do this, but I forgot.
I ended up just plugging the numbers in to see if they worked;
120(4) + 120 is too much to be 150;
40(4) + 40 is 200, still too much to be 150;
30(4) + 30 is 150, exactly
So your answer is C, 30.
Hope this helps!

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

Write the equation of the line fully simplified slope-intercept form.
Answer:
y=-3/2x+5
Step-by-step explanation:
you look for your y-intercept first then you find 2 points and do rise over run to get y=-3/2x+5
The difference in the x-coordinates of two points is 3, and the difference in the y-coordinates of the two points is 6. Wha
is the slope of the line that passes through the points?
A) 2
B) 3
C) 6
D) 9
Answer:
2
to find the slope you get the rise which is the difference between the y coordinates over the run which is the difference between the x coordinates. so 6/3=2

Solve the system by substitution
x=y
6x-3y=30
Answer: (x, y) = (10, 10)
Since x = y, replacing y with x in 6x - 3y = 30 we have 6x - 3x = 3x = 30, so x = 30/3 = 10. Then y = x = 10, so the solution is (10, 10).

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.

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
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

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

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.

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 )

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!!
