Let
x-------------> <span>the length of a rectangle
y-------------> the </span>width of a rectangle
we know that
x+y=130-----------> equation 1
and
x=1.6y--------------> equation 2
<span>I substitute 2 in 1
(1.6y)+y=130-------------> 2.6y=130------------> y=130/2.6------> y=50 ft
x=1.6y--------> x=1.6*50---------> x=80 ft
the answer is
</span>the length is 80 ft
the width is 50ft

Answer:
![\dfrac{7}{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B7%7D%7B10%7D)
Step-by-step explanation:
We need to find a rational number between 3/5 and 4/5.
We can find a rational number between two fractions as :
![\dfrac{a+b}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7Ba%2Bb%7D%7B2%7D)
We have, a = 3/5 and b = 4/5
So,
![\dfrac{\dfrac{3}{5}+\dfrac{4}{5}}{2}\\\\=\dfrac{\dfrac{7}{5}}{2}\\\\=\dfrac{7}{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cdfrac%7B3%7D%7B5%7D%2B%5Cdfrac%7B4%7D%7B5%7D%7D%7B2%7D%5C%5C%5C%5C%3D%5Cdfrac%7B%5Cdfrac%7B7%7D%7B5%7D%7D%7B2%7D%5C%5C%5C%5C%3D%5Cdfrac%7B7%7D%7B10%7D)
So, a rational number between 3/5 and 4/5 is equal to 7/10.
Answer:
Tuesday
Step-by-step explanation:
Let the days of the week be numbered 1–7, starting with Monday and ending with Sunday. Let <em>t</em> represent today. We can equate the number of skirts finished by Friday (day 5) with the ones finished by Sunday (day 7) at the lower rate. (days × (skirts/day) = skirts)
... (5-t)×5 = (7-t)×3
... 25 -5t = 21 -3t . . . . . eliminate parentheses
... 4 = 2t . . . . . . . . . . . . add 5t-21
... 2 = t . . . . . . . . . . . . . divide by 2
Day 2 corresponds to Tuesday.
_____
<em>Check solution</em>
(5-2)·5 = 15 = (7-2)·3 skirts are being made.
Answer:
-8x + 6
Step-by-step explanation:
Subtract "5x-2" from "-3x + 4". Set the equation.
(-3x + 4) - (5x - 2) = Answer (A)
First, distribute -1 to all terms within the second parenthesis.
-3x + 4 - 5x + 2 = A
A = -5x - 3x + 4 + 2
Simplify. Combine like terms (terms with the same amount of variables).
A = (-5x - 3x) + (4 + 2)
A = -8x + 6
-8x + 6 is your answer, or the first answer choice.
