Answer:
The team won 10 games.
Step-by-step explanation:
The statement indicates that the football team played a total of 16 games, which means that the total number of games they won, lost or tied is equal to 16 and you can express this as:
x+y+z=16, where:
x is the number of games the team won
y is the number of games the team lost
z is the number of games the team tied
As you know that they tied one game, it means that z=1:
x+y+1=16
x+y=16-1
x+y=15
Also, the statement says that they won twice as many games as they lost which means that the number of games they won is equal to two times the number of games they lost, which is:
x=2y
Now, you can replace x=2y in x+y=15 and solve for y:
2y+y=15
3y=15
y=15/3
y=5
Finally, you can replace the value of y in x=2y in order to find the value of x:
x=2(5)
x=10
According to this, the answer is that the team won 10 games.
What is (3p+7)(3p-7)(p+8)
Answer:
9p^3 + 72p^2 - 49p - 392
Step-by-step explanation:
(3p + 7) times (3p - 7) times (p + 8)
(9p^2 - 49) times (p +8)
9p^3 + 72p^2 - 49p - 392

Is (8, 3) a solution to the system?
- x + 4y = 4
- x + 3y = 1
Answer:
Step-by-step explanation:
You can either substitute (8, 3) into both equations as a test, or you can find the solution yourself.
Rewrite
- x + 4y = 4
- x + 3y = 1
as
- x + 4y = 4
+ x - 3y = -1
and combine like terms. The result is y = 3. Then -x + 4(3) = 4, or 8 = x.
Yes, (8, 3) is a solution of this SYSTEM.

Find the value of x. -1x + 72 = -3x + 84
Answer:
x=6
Step-by-step explanation:
First, add x to each side.
72=-2x+84
Subtract 84 from each side
-12=-2x
Dive each side by -2
6=x
Answer:
x=6
Step-by-step explanation:
-1x+72=-3x+84
+3x on both sides
2x+72=84
subtract 72 on both sides
2x=12
divide by 2 on both sides
x=6

Recall that two angles are complementary if the sum of their measures is 90. Find the measures of two complementary angles if one angle is 15 degree more than two times the other angle.
Answer: 25° and 65°
Step-by-step explanation:
Let the smaller angle of the complementary angle be represented by x.
Since the other angle is 15 degree more than two times the other angle, this will be:
= (2 × x) + 15°
= 2x + 15°.
Then we add both angles together and equate them to 90° and this will be:
x + 2x + 15° = 90°
3x + 15° = 90°
3x = 90° - 15°
3x = 75°
x = 75°/3
x = 25°
Then the other angle will be:
= 2x + 15°
= (2 × 25°) + 15°
= 50° + 15°
= 65°
Therefore, the angles are 25° and 65°.
I would really like help for this, if anyone is willing to help me.

Sarah hiked a path that took her from 34 feet below sea level to 52 feet above sea level . What was the change in her elevation?
Answer:
86 ft
Step-by-step explanation:
First method: Logical thinking
Think of the position 34 ft below sea level as -34.
The position above sea level is 52.
You need to find the distance between -34 and 52.
You go from 34 ft below sea level, -34 to 0. That is 34 ft.
Then you go from sea level, 0 ft, to 52 ft above sea level. That is 52 ft.
The total is 34 ft + 52 ft = 86 ft
Answer: 86 ft
Second method: Calculate a distance in math
The distance between two points on a number line is the absolute value of the difference of their coordinates. The coordinates are -34 and 52. Subtract the numbers in either order, and take the absolute value of the difference.
|-34 - 52| = |-86| = 86
If you did it in the other order, you'd get the same answer.
|52 - (-34)| = |52 + 34| = |86| = 86
Answer: 86 ft

A rectangular room is 7 times as long as it's wide and it's perimeter is 64metres. Find the dimension of the room.
Answer:
Length = 28 meters Width = 4 metersStep-by-step explanation:
Assume the width of the rectangle is x. That means that the length of the rectangle is 7x which is 7 times as long as it is wide.
Perimeter of a rectangle:
= Length + length + Width + Width
Therefore:
7x + 7x + x + x = 64
16x = 64
x = 64/16
x = 4 meters
Length is 7 times as long:
= 4 * 7
= 28 meters

Answer:
4 white horses.
Step-by-step explanation:
First, you need to find the total of the first set of horses (basically how many total were in the table).
~ 3+2+9+1 = 15
Next we need to find how many horses were white horses out of these 15 horses. In short the proportion would be White Horses/Total Horses.
~ [tex]\frac{3}{15}[/tex] (or [tex]\frac{1}{5}[/tex], simplified)
Now, all we need to do is create the proportion with 20 as the denominator (in this case, 20 will be the total horses, and we just need to find X, or how many horses are expected to be white out of all of those horses). The proportion will look somewhat like this:
~ [tex]\frac{1}{5}[/tex] = [tex]\frac{x}{20}[/tex]
The final step is to multiply across (1x20) then divide that number by the 5 to find X.
~ 20÷5 = 4
Anyways, that means it would be expected to have 4 white horses out of 20 total. Hope this helped ^-^

Evaluate 2-10+8-\left(-2\right)2−10+8−(−2)2, minus, 10, plus, 8, minus, left parenthesis, minus, 2, right parenthesis.
Answer:
Here we want to solve the equation:
"2, minus, 10, plus, 8, minus, left parenthesis, minus, 2, right parenthesis."
This can be written as:
2 - 10 + 8 - (-2)
Remember that we can solve this in any order we want, so let's go from left to right:
So we can solve first:
( 2 - 10) + 8 - (-2)
We know that:
2 - 10 = -8
Then we can replace that in the expression to get:
( 2 - 10) + 8 - (-2) = -8 + 8 -(-2)
Now we can solve:
(-8 + 8) - (-2)
We know that:
-8 + 8 = 0
Replacing that in the equation we get:
(-8 + 8) - (-2) = 0 - (-2) = -(-2)
And now we can remember the rule of the signs:
(+)*(+) = (+)
(-)*(-) = (+)
(-)*(+) = (-)
(+)*(-) = (-)
Then:
-(-2) = (-1)*(-2) = +(1)*(2) = 2
The solution of the expression is 2.
Answer:
The answer is 2

What is the equation of a line parallel to the y axis and passing through the point (2,1)?
Answer:
x = 2
Step-by-step explanation:
lines parallel to the y-axis are always vertical and begin with 'x ='
Answer:
x=2
Step-by-step explanation:
Hi there!
A line parallel to the y-axis would make it a vertical line. Vertical lines have the equation x=d, where d is the x-intercept (the value of x when y=0).
We also need to know that every point a vertical line passes through has the same x-coordinate. Therefore, because this line passes through the point (2,1), we know that the x-intercept is (2,0).
Therefore, the equation of the line would be x=2.

does it have?
Euler's Formula: F+ V - E = 2
Fnter
Answer:
4 edges
Step-by-step explanation:
the shape is a cube
Answer: 12
Step-by-step explanation:
Euler’s formula: F + V - E = 2
6 + 8 - E = 2
14 - E = 2
You find E by subtracting 14 with 2
14 - 2 = 12
E = 12
In order, range, median, mode and mean. Round the mean to the nearest tenth.
PLS HELP ASAP
Answer:
Range: 40
Median: 55
Mode: 72
Mean: 54.6
Step-by-step explanation:
First, let's put all of the numbers down.
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
Now, to find the range, subtract 72 - 32 = 40
To find the median, find the number in the middle
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
Because there are an even amount of numbers we will find the mean of those two numbers which would be 55.
To find the mode, look for the number that appears the most.
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
To find the mean, add everything up.
32, + 34, + 35, + 40, + 41, + 54, + 54, + 56, + 63, + 69, + 70, + 72, + 72, + 72 = 764
Then, divide. 764 ÷ 14 = 54.6 when rounded to the nearest tenth.
I hope that this helps, and you have a great day! :)
