What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?
AnnZ [28]

The value of n in given proportion is 16

<u><em>Solution:</em></u>

We have to find the value of "n" in the proportion

<em><u>Given proportion is:</u></em>

<em><u></u></em>\frac{n}{28} = \frac{4}{7}<em><u></u></em>

We can solve the above proportion by cross-multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable

->\frac{n}{28} = \frac{4}{7}

-> 7 *  n = 4 * 28

-> n = \frac{4 * 28}{7}

-> n = 4 * 4 = 16

Thus the value of n in given proportion is 16

7r²+9=1 quadratic equation.
dezoksy [38]
<span>7r²+9=1 

</span><span>the equation is contradictory, just to prove

7r</span>² + 9 = 1

7r² + 9 -1 = 0

7r² + 8 = 0

<span>We write the equation in the form of products of
</span>
7 * (r² + 8/7) = 0

<span>the product is equal to 0 when one of the factors is zero
</span>
7≠0      ∨      (r² + 8/7) = 0
                     r² ≠ - 8/7
<span>any number squared is not negative.

</span><span>We proved that none of the factors is not equal to zero , so the right side of the equation is not equal to the left . The equation is contradictory</span>

If the radius of a circle with a area of 5.3 mm squared is multiplied by 5,
chubhunter [2.5K]
I'm guessing the question is meant to be "<span>If the radius of a circle with a area of 5.3 mm squared is multiplied by 5, what will the new area be?", so i'll answer that.

Area of a circle =</span>πr^2

5.3=πr^2, 5.3=π(5r)^2
132.5=25πr^2
