Lily had 16 stamps and Mackenzie had 20 stamps.
Step-by-step explanation:
Lily gives 4 stamps to Mackenzie
(Mackenzie) m + 4 = 2(L - 4) (Lily)
Solve for Lily:
m + 4 = 2L - 8
m + 4 + 8 = 2L
(m + 12) ÷ 2 = 2L ÷ 2
(m + 12) ÷ 2 = L
L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)
Mackenzie gives 4 stamps to Lily
(Mackenzie) m - 4 = L + 4 (Lily)
m - 4 = ((m + 12) ÷ 2) + 4
m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4
2m - 4 + 4 = (m + 12) + 4 + 4
2m - m = (m - m + 12) + 8
m = 12 + 8
m = 20 (we will substitute this value of m in the next equation)
L = (m + 12) ÷ 2
L = (20 + 12) ÷ 2
L = 32 ÷ 2
L = 16

Answer:
y = 4x + (-9)
Step-by-step explanation:
You can observe that the line crosses the y-axis at -9, so that is our y-intercept.
For the slope, just take the y-intercept for example, and count how many squares the line goes up before reaching 1. In this problem you can see that the line goes 4 squares up in the time it takes to go 1 square to the right, so the slope is y over x, meaning 4 over 1, or just 4.
Answer:
The answer should be y = 4x + (-9).

May someone help me with this. The question is in the picture.
Answer:
first we have to find oput how many they accepted, 60% of 10,000 is 6000. Next we have to find out how many of those 6000 will actually enroll.
to find 40% of 6000 we can first find 10% which is 600, so 600x4=2400 or 40% of 6000.
2400 will actually enroll

Step-by-step explanation:
First find out what the ratio of tulips and roses is for each garden.
Ben: 40÷(4+1) = 8 so 8×4=32 and 8×1= 8
Ina: 40÷(2+5) =5.7 so 2×5.7=11.4 and 5×5.7= 28.6
Use these numbers accordingly.

Walmart marked up a bottle of nail polish 150% in order to make profit. if Walmart sells the nail polish for $8.75, what was the original cost of the polish?
The original price of the nail polish with a 150% markup sold at $8.75 is $3.50.
Let x be the original price of the polish.
Walmart marked up 150%.
Selling Price = Original Cost + Mark-up
therefore the selling price = x + 150% of x
we know the selling price is $8.75
Therefore, substituting the values:
8.75 = x + 150% of x
convert percentages to decimals:
8.75 = x + 1.5x
combine like terms:
8.75 = 2.5x
divide by 2.5 into both sides:
3.5 = x
use reflexive property:
x = $3.50
Thus, the original price of the nail polish is $3.50.

Mike jogged a total distance of 5 1/3 miles during the months of October and November. If Mike only jogger 1/6 mile every day, Which expression shows the number of days in which he went jogging?
Answer:
D
Step-by-step explanation:
If he jogged [tex]x[/tex] miles every day, and he jogged a total distance of [tex]y[/tex] miles, then he runs for [tex]y/x[/tex] days. This is an extension of the [tex]d=rt[/tex] or distance equals rate times time.
We plug in for y and x to get that he runs for [tex]5~1/3~~/~~1/6[/tex].
So, the answer is [tex]\boxed{D}[/tex] and we're done!
