One side of a rectangle is 3 times the length of another side. The difference in their lengths is 10 feet
elena55 [62]

Answer:

5 feet & 15 feet

Step-by-step explanation:

<em>The question is to find the lengths of 2 sides of the rectangle</em>.

<u>Solution:</u>

Let shorter side be "x"

Let longer side be "y"

From the question, we can write:

y = 3x

also

y - x = 10

Now, putting the first on second equation, we get:

y - x = 10

3x - x = 10

2x = 10

x = 10/2 = 5

Now, y = 3x, y = 3(5) = 15

So we can say the lengths of 2 sides of the rectangle is 5 feet & 15 feet

90 x= 81 + 25 <br> I need help ?
charle [14.2K]

Answer:

x = \frac {53} {45}

Step-by-step explanation:

<u>Step 1:  Combine on the right side </u>

90x = 81 + 25

90x = 106

<u>Step 2:  Divide both sides by 90 </u>

\frac {90x} {90} = \frac {106} {90}

x = \frac {106/2} {90/2}

x = \frac {53} {45}

Answer:  x = \frac {53} {45}
