Steven and Bob both have a Pokemon card collection. The number of Pokemon cards in Steven's collection can be represented by x. The number of cards in Bob's collection is 4 times the amount in Steven's collection. The total number of Pokemon cards in both collections is 240. What is the number of cards in Steven's collection?
Answer: 48
Step-by-step explanation:
The number of Pokemon cards in Steven's collection = x
The number of cards in Bob's collection is 4 times the amount in Steven's collection= 4x
The total number of Pokemon cards in both collections = 240
x + 4x = 240
5x = 240
x = 240/5
x = 48
The number of cards in Steven's collection is 48
How should I get rid of the 5
A divide by 5
B multiply by 5
Divide by 5, if question is a multiplication
But, multiply by 5 if question is based on division.
So, you're basically doing the inverse, of the operations you've been given.
For example:
x/5 = 2
x5 ( Multiply by 5)
x = 10
3 x y = 12
÷3
y = 4

187 minutes and is broken into two parts. The second part of the movie is 11 minutes langer than the first part. How many minutes is Part 2?
Answer:
99 minutes
Step-by-step explanation:
Let the variable x represent the longer part of the movie. Then the shorter part is (x-11) and the total length is the sum of the parts:
187 = x +(x -11)
198 = 2x
x = 99
The length of Part 2 is 99 minutes.
PLEASE ANSWER THIS ASAP !!!!!
Answer:
-22
Step-by-step explanation:
First, you must find the values for f(-8) and g(2). f(x) is the blue line so f(-8)=-2 because that is the value of y where x=-8. g(x) is the pink dotted line so g(2)=-4 because that is the value of y where x=2. Then, plug in and solve:
-3(-2)+7(-4)
6+-28
6-28
-22

=================================================
Explanation:
Check out the diagram below.
Plot R(-3,7) and T(3,-11) on the same xy grid.
Draw a vertical line through R and a horizontal line through T. A right triangle forms. At the intersection point is point S(-3,-11)
----------------------
Now measure the distance from point S to point T. You can count out the spaces or subtract the x coordinates and use absolute value.
|x1-x2| = |-3-3| = |-6| = 6
From point S to point T is 6 units.
We want to subdivide this horizontal length in the ratio 1:2
What this means is that we want to plot a point U somewhere such that SU:UT = 1:2
In other words,
SU = x
UT = 2x
SU+UT = ST
x+2x = 6
3x = 6
x = 6/3
x = 2
So we must move 2 spaces to the right from point S to get to U(-1,-11)
Going from point U(-1,-11) to T(3,-11) is 4 spaces
We have SU:UT = 2:4 = 1:2 to help confirm we have the correct location for point U
From point U, we then move straight up to the line segment RT
We'll land on Q(-1,1)
----------------------
Another way to find the y coordinate of point Q is to subdivide the segment RS into the ratio 1:2 similar to how we divided ST up
Segment RS is 18 units long since we go from y = 7 to y = -11 when going from R to S.
If V was on segment RS such that
RV:VS = 1:2
and RV = y
then
RV+VS = RS
y+2y = 18
3y = 18
y = 6
RV = y = 6
VS = 2y = 2*6 = 12
So you'll move 6 units down from y = 7 to land on y = 1 (when going from the y coordinate of R to the y coordinate of Q)

Please help me ASAP
Answer:
slope= 2 I case you need that :)
Answer:
Below.
Step-by-step explanation:
One way is to plot some points:
When x = 0, y = 2(0) - 4 = 4 So plot (0,-4).
In a similar way you can plot when x = 1, y = 2(1) - 4 = -2 that is (1, -2).
Also 2(3) - 4 giving the point (3, 2).
Now draw a line passing through these 3 points.
If you cant draw a line through these points then Ive made a mistake in the calculations
M is directly proportional to L^3
When L = 2, M= 160
Find the value of M when L = 3
Answer:
2,160
Step-by-step explanation: since M is proportional to L^3 so when L=2 then L^3=8 so M=160 which means if L = 3
When L = 3, the value of M is 540. The relationship between M and L³ holds true.
When two variables, M and L, are directly proportional, it means that their ratio remains constant.
In this case, M is directly proportional to L³, which can be written as M = k × L³, where k is the constant of proportionality.
To find the value of k, we can use the given information when L = 2, and M = 160:
160 = k × 2³
160 = k × 8
k = 160 / 8
k = 20
Now that we have the value of k, we can find the value of M when L = 3:
M = 20 × 3³
M = 20 × 27
M = 540
So, when L = 3, the value of M is 540. The relationship between M and L³ holds true for any value of L when multiplied by the constant of proportionality k, which we found to be 20 in this case.
