Answer: The length of the rectangle is 16 yards and the width is 12 yards.
Step-by-step explanation:
The length is 4 yds longer than the width. Let's remove that from the perimeter so that the perimeter will be as if all sides had the same length (remember there are 2 sides for length and 2 sides for width).
Now we made it so that the extra 4 yards are gone and all sides are equal like a square. Now we can divide by 4 to determine the length of each of the now equal sides
So all of the sides are 12, 12, 12, and 12. To two of the sides we can add back the extra 4 yards we took out giving us sides of 12, 12, 16, and 16.
Let's add it all together and see if it makes the perimeter of 56
It does! Since the length is 4 yds longer than the width the length is 16 and width is 12.
Equation: 4x + 2 = x - 7
Solve equation
Subtract x from both side
3x + 2 = -7
Subtract 2 from both side
3x = -9, x = -3
Solution: the number is -3
Answer:
The equation would be y = -3x - 9
Step-by-step explanation:
Since we have the slope of 1/3, we know the slope of a perpendicular line would be -3. This is because perpendicular lines have opposite and reciprocal slopes. We can then use this and the point to solve in point-slope form.
y - y1 = m(x - x1)
y - 3 = -3(x + 4)
y - 3 = -3x - 12
y = -3x - 9
15% of 25 = 3.75
0.15 x 25 = 3.75
If you only have a piece of wood 7/8 feet long and you cut off a 1/4 feet piece, you are left with 5/8 foot board. all you have to do is to subtract 7/8 - 1/4.
7/8 - 1/4 = 7/8 - 2/8 = 5/8
