Answer:
You have 3 pennies and your friend has 1 penny
Step-by-step explanation:
The given parameters are;
Let friend A = you
friend B = Your friend
The number of pennies with friend A when he gives friend B 1 penny = Equal number of pennies between friend A and B
The number of pennies with friend A when he is given 1 penny by friend B = 2 times the number of pennies with friend B
Let the number of pennies with friend A = X and the number of pennies with friend B = Y, therefore, we have;
X - 1 = Y + 1.....................(1)
X + 1 = 2 × Y...................(2)
Subtracting equation (1) from equation (2), we get;
X + 1 - (X - 1) = 2·Y - (Y - 1)
X - X + 1 + 1 = 2·Y - Y + 1
2 = Y + 1
Y = 2 - 1 = 1
Y = 1
From equation (1), X - 1 = Y + 1 gives;
X - 1 = 1 + 1
X = 1 + 1 + 1 = 3
Friend A has 3 pennies and friend B has 1 penny.
Therefore, you have 3 pennies and your friend has 1 penny

ethan made a rectangular prism that has a volume of 16 cubic inches. What is one set of possible dimensions for ethans rectangular prism?
Answer:
0.5 inches by 0.5 inches by 64 inches
Step-by-step explanation:
Any three positive dimensions that have a product of 16 will be a set of possible dimensions. There are an infinite number of them. One such is listed above.
(If you have a list of answer choices, you can multiply them out to see which have a product of 16. We cannot guess what your choices might be.)

the sum of 2 numbers is 16, and the sum of their squares is 146. find the 2 numbers
Step-by-step explanation:
x + y = 16 (*)
x^2 + y^2 = 146 (**)
(*) <=> x= 16-y
substitute x = 16 - y
(**) <=> (16-y)^2 + y^2 = 146
<=> y^2 - 2.16.y + 16^2 + y^2 = 146
<=> 2y^2 - 32y + 110 = 0
<=> y^2 - 16y + 55 = 0
<=> (y-11)(y-5) = 0
<=> y=11 or y= 5
For y = 11, we have x= 16-11=5
For y=5, we have x= 16-5=11
Answer: (x,y) = (11,5) ; (5,11)

2x+9+103=180
2x+112=180
2x=68
x=34
Let me know if this helps :)
Answer:
34 degrees
Step-by-step explanation:
(2x+9) degrees and 103 degrees form a linear pair
Therfore, the sum of these two angles = 180
(2x+9)+103=180
=>2x+112=180
=>2x=180-112
=>2x=68
=>x=68/2
=>x=34
The value of x is 34 degrees
A population of caribou in a forest grows at a rate of 6% every year. If there are currently 258 caribou, which function represents the number of caribou in the forest in t years?
Answer:
P(t) = 258( 1 + 6%)^t
Step-by-step explanation:
Given that the population of caribou in a forest grows at a rate of 6% every year. If there are currently 258 caribou, the function representing the number of caribou in the forest in t years will be
P(t) = 258( 1 + 6%)^t
Since it is increasing, it will be 1 + 6%
Where P(t) is the function representing the population after t years.
258 is the current or initial population.

Step-by-step explanation:
on a ten by ten graph this is the included file
(sorry for my bad lines, i had to do this with a mouse0
Answer:
see the attachment for a graph
Step-by-step explanation:
We can't tell what your instructions are. Many graphing tools will let you click on the locations of the points, then draw a line through them. The attached image is from one such tool.
__
If you want to plot this by hand, you do it essentially the same way: plot the two points and draw a line through them.
If you want to write an equation for the line, you can start with the 2-point form:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (5 -(-3))/(2 -(-4))(x -(-4)) -3
y = 8/6(x +4) -3
y = 4/3x +16/3 -9/3
y = 4/3x +7/3
__
Personally, about the only thing useful I find in this equation is that it tells you the slope is 4/3. You can determine the same thing by counting grid squares between the plotted points on the graph. The line goes up 8 for each 6 to the right, so slope = rise/run = 8/6 = 4/3.

A machine is used to fill each of several bags with 16 ounces of sugar. If the bag
weights 0.3 ounces more or less than the desired weight, the bag is rejected. Write
this equation to find the heaviest and lightest bag the machine will approve.
Answer: 15.7oz < M < 16.3oz
Step-by-step explanation:
The average mass of each bag will be 16oz
If the bag weighs 0.3 oz more or less than 16 oz, then it is rejected.
Then the extremes are:
16oz - 0.3oz = 15.7oz (this mas counts as a rejected one)
So we have that the mass of the bag must be larger than 15.7oz
M > 15.7oz
Now, the other extreme is:
16oz +0.3oz = 16.3oz (again, this a rejected mass)
Then the mass of the bag must be smaller than 16.3oz
M < 16.3oz
Then the range of the accepted mass of the bags is:
15.7oz < M < 16.3oz
118 - [121 - (11 × 11) - (-4) - 3 - 9 - 2]
Answer:
Step-by-step explanation:
118 - [121 - ( 11 x 11 ) - ( - 4 ) - 3 - 9 - 2]
118 - [121 - 121 + 4 - 3 - 9 - 2]
118 - [4 - 3 - 9 - 2]
118 - [1 - 9 - 2]
118 - [-8 - 2]
118 - (-10) or 118 - 1(-10)
Negative times negative equals to positive.
118 + 10= 128

Answer:
-2x^3 +13x^2 +3x -54

The double number line below shows the price for a certain number of packs of popcorn at a store. Which statement correctly gives and explains the price of 9 packs of popcorn? Two number lines are shown one above the other. The number line on the top is labeled and marked at 2, 4, 6, 8. On the left of this number line is written Packs of Popcorn. The number line below it is labeled and marked at 14, 28, 42, 56. On the left of this number line is written Price of Packs in brackets dollar sign $18, because the price of each pack is $2 $63, because the price of each pack is $7 $108, because the price of each pack is $12 $126, because the price of each pack is $14
