A class walked 2.5 miles for a walk-a-thon.
How many yards did the class walk?
Answer:
4400 Yards
Step-by-step explanation:
A mile equals 1,760 yards. 2.5 times 1,760 gives you 4,400
It is given that A class walked 2.5 miles for a walk-a-thon then the class walked 4400 yards.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
It is given that A class walked 2.5 miles for a walk-a-thon.
WE are asked How many yards did the class walk.
A mile equals 1,760 yards.
If one mile is 1760 yards, then the answer should be
= 1760 times the number of miles.
So 1760*2.5 = 4400
Hence, the class walked 4400 yards.

Step-by-step explanation:
Opening bracket,
6x+15 +4=7
6x=7-19 (I took 15 and 4 to other side and thus they became negative)
x=-12/6
x=-2
Pls mark me brainliest
Answer:
The answer is x = -2
Step-by-step explanation:
FOIL
3*2x + 3*5 + 4 = 7
6x + 15 + 4 = 7
6x + 19 = 7
Subtract 19 from both sides.
6x = -12
Divide both by 6.
x = -2

Alexandria High School scored 37 points in a football game. Six points are awarded for each touchdown. After each touchdown, the team can earn one point for the extra kick or two points for a 2-point conversion. The team scored one fewer 2-point conversions than extra kicks. The team scored 10 times during the game. How many touchdowns were made during the game?
Answer:
Five touchdowns were made in the game
Step-by-step explanation:
Here, we want to know the number of touchdowns made during the game.
We proceed as follows;
Let the number of touch downs be x
So the total points earned through touchdowns is 6 * x = 6x
The number of scores is 10 times
Let the number of extra kick be y which means that the number of conversions will be (y-1)
So the total number of score times will be ;
x + y + y-1 = 10
x + 2y = 11 •••••••••(i)
Now let’s work with points
Touch down points = 6 * x = 6x
Points from extra kick = 1 * y = y
Points from 2-point conversions = 2(y-1) = 2y - 2
So;
6x + y + 2y -2 = 37
6x + 3y = 37 + 2
6x + 3y = 39
divide through by 3
2x + y = 13 •••••••(ii)
So now solve simultaneously
From ii, y = 13 - 2x
Put this into i
x + 2(13-2x) = 11
x + 26 - 4x = 11
x -4x = 11-26
-3x = -15
x = -15/-3
x = 5
There are five touchdowns in the game
Answer:
x = -15/-3
Step-by-step explanation:
Five touchdowns were made in the game
Step-by-step explanation:
Here, we want to know the number of touchdowns made during the game.
We proceed as follows;
Let the number of touch downs be x
So the total points earned through touchdowns is 6 * x = 6x
The number of scores is 10 times
Let the number of extra kick be y which means that the number of conversions will be (y-1)
So the total number of score times will be ;
x + y + y-1 = 10
x + 2y = 11 •••••••••(i)
Now let’s work with points
Touch down points = 6 * x = 6x
Points from extra kick = 1 * y = y
Points from 2-point conversions = 2(y-1) = 2y - 2
So;
6x + y + 2y -2 = 37
6x + 3y = 37 + 2
6x + 3y = 39
divide through by 3
2x + y = 13 •••••••(ii)
So now solve simultaneously
From ii, y = 13 - 2x
Put this into i
x + 2(13-2x) = 11
x + 26 - 4x = 11
x -4x = 11-26
-3x = -15

The required value of cos(2x) is -7/25. Option B is correct.
sinx = 4/5
cosx < 0
Trigonometry is the study of angles in mathematics.
Here,
cos(2x) = 1-2sin²x
= 1 - 2 x 4²/5²
= 1 - 32/25
cos(2x) = -7/25

Seth is making panels for a stained-glass window. He makes a triangular pane shaped like the triangle shown. Which of these rectangular panes has the same area as the triangular pane?
Help me please! I will mark brainliest whoever answers this with the right answer
Answer:
Options A and C
Step-by-step explanation:
Area of the triangular pane = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(14)(12)[/tex]
= 84 cm²
Area of the rectangle is given by the formula,
Area = Length × width
Option A.
Area of the rectangular pane = 12 × 7
= 84 cm²
Option B.
Area of the rectangular pane = 15 × 7
= 105 cm²
Option C.
Area of the rectangular pane = 21 × 4
= 84 cm²
Option D.
Area of the rectangular pane = 21 × 8
= 168 cm²
Option E.
Area of the rectangular pane = 28 × 6
= 168 cm²
Therefore, rectangular panes A and C have the equal area as the triangular pane has.

In the decimal system, when we divide a number by 10, the rightmost digit in the number is the remainder. Divide the number 157 by 10 repeatedly. Each time, write the remainder in the last column and the quotient in the dividend column. You can stop dividing when you get a 0 in the dividend column.
Answer:
See explanation
Step-by-step explanation:
Required
Divide 157 by 10 repeatedly.
This is done as follows...
157 Divided by 10 = 15 Remainder 7
15 Divided by 10 = 1 Remainder 5
1 Divided by 10 = 0 Remainder 1
