The length of a rectangle is 3 times the width, and the perimeter is 22. Find the dimensions of the rectangle.
1 answer:
<span> Ok, so first you know that the length=3 times the width, or width=x and length=3x.
To find the perimeter of a rectangle, you add the lengths of all the
sides, so you add the width+width+length+length, or x+x+3x+3x.
This is then simplified into Perimeter=8x.
Since the perimeter is 22, you substitute it into the equation:
22=8x
Then, simply solve for x by dividing 22 by 8. The answer is x=2.75.
Since width=x and length=3x, width=2.75 and length=3 (2.75), or length=8.25.
Therefore, the dimensions of the rectangle are width of 2.75 and length of 8.25.
Hope it helps :] </span>

Answer:
2.2gpa
Step-by-step explanation:
you add the value if the letter grades up and divide by how many classes you have. for this case you have 5 and you would add 4+3+2+1+0=10/5=2.2
Y=mx+b
m=slope
b=y-intercept
Given
Slope=-4/3
y-intercept=-2
Plug them into the slope intercept formula
Final answer: y=-4/3-2
