The length of a rectangular picture frame is 4 inches less than three times the width. The perimeter is 136 inches. Find the len
natulia [17]

Answer:

The width of the rectangle is 18 inches, and the length is 50 inches

Step-by-step explanation:

We can designate a variable, x, to represent the width of the rectangle.  To represent the length and widths of the rectangle, we can say that the length is 3x-4 and the width is just x.  We can then write an equation for the perimeter and solve:

2(3x-4) + 2x = 136

6x - 8 + 2x = 136

8x - 8 = 136

8x = 144

x = 18

To calculate the length

(3x - 4)

3(18) - 4 = 50 in

3. The equation 4x + 16y = 36 is a true equation for a particular
Kazeer [188]

Answer:

See below.

Step-by-step explanation:

We know that the equation 4x+16y=36 is a true equation for a particular value of x.

Now, let's see what happens if we divide everything by 4. In other words:

\frac{4x+16}{4}=\frac{36}{4}

Divide:

x+4=9

So, we get x+4=9.

When we divided everything by 4, we used the division property of equality. Under this property, the equation remains the same even if we divided since we did the <em>same thing to both sides of the equation. </em>

Therefore, x+4y=9 is also true for the same value of x because it is just a simplified version of 4x+16y=36.

How do I solve for x?
grandymaker [24]

Answer:

The answer is 98

Step-by-step explanation:

Subtract the sum of the two angles from 180 degrees.

The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

62+20=82

180-82=98

98+20+62=180
