#10. Maddy had twice as many stamps as Simon. After Maddy sold 60 stamps, Sinom had twice as many stamps as Maddy. How many more stamps did Maddy have than Simon in the beginning?
Answer:
8. $114
10. 60 stamps
Step-by-step explanation:
8.
Let Dylan have d, Mike have m, and Jeremy have j
3 of them have 171, so we can write:
1.
Mike has twice as Dylan, so we can write:
2. m = 2d
Jeremy had three times as Mike, so:
3. j = 3m
We can write equation 3 as m = j/3
Also, if we put this into equation 2, we have:
j/3=2d
d=j/6
Now we have d and m in terms of j. We put it into equation 1 and solve for j:
Jaime has $114
10.
amount of stamps Maddy has is m and amount Simon has is s
Maddy had twice as many stamps as Simon:
m = 2s
Also
After Maddy sold 60 stamps, Sinom had twice as many stamps as Maddy:
s+60=2(m-60)
We put the first equation in the second and solve for s:
s+60=2(m-60)
s+60=2(2s-60)
s+60=4s-120
180=3s
s=60
THus, m = 2(60) = 120
So maddy had 120 - 60 = 60 more stamps than Simon

Answer:
2¹²
Step-by-step explanation:
= 16³
We'll divide 16 into the product of its prime factors
= ( 2×2×2×2)³
There are four 2s so it becomes 2⁴
= (2⁴)³
= 2⁴ˣ³
= 2¹²
Answer:
2^12
Step-by-step explanation:
16^3 = (2^4)^3 = 2^(4x3) = 2^12
Hope this helps!
You will have the points: (0,0) and (1,10) and (2,20) and (3,30) etc etc
Plot at least 2 of these points. Then draw a line through them.
Each point has an x,y pair such that the y value is ten times the x value
For example, if x = 2, then
y = 10*x = 10*2 = 20
so that shows how (2,20) is one of the points.
-------------------
The domain would be the set of positive whole numbers assuming Tyler can only work a whole number of hours. If partial time values are accepted, then the domain would be the set of positive real numbers. Negative x values are not allowed as Tyler can't work negative 3 hours for instance.
In a similar fashion, the range is the set {0, 10, 20, 30, 40, ...} incrementing by multiples of 10 if x is the set of positive whole numbers. If x is the set of positive real numbers, then y can be 0 or larger which sets up the range of y being the set of positive real numbers as well.

Step-by-step explanation:
She will be making 168 greeting cards.
In math, to multiply means to add equal groups. When we multiply, the number of things in the group increases.
Given is that Karen is making 14 different kinds of greeting cards. She is making 12 of each Kind.
The total number of greeting cards she is making are -
14 x 12
168
Therefore, she will be making 168 greeting cards.
