Circles M and K are congruent, QR is congrent to LN. Find the length of QR
Novosadov [1.4K]

Given QR is congrent to LN and QR = 4x + 2 and LN = x + 7.

So, QR = LN

Hence, we can set up an equation as following:

4x + 2 = x + 7

4x + 2 - x = x + 7 - x Subtract x from each sides.

3x + 2 = 7 By simplifying.

3x + 2 - 2 = 7 - 2 Subtract 2 from each sides.

3x = 5

\frac{3x}{3} =\frac{5}{3} Divide each sides by 3 to isolate x.

So, x=\frac{5}{3}

Next step is to plug in x=\frac{5}{3} in QR = 4x+2 to get length of QR.

So, QR = 4(\frac{5}{3})+2

=(\frac{20}{3})+\frac{2}{1} Since 2 can be written as 2/1.

By multiplying the second fraction by the common denominator 3.

=(\frac{20}{3})+\frac{2*3}{1*3}

=(\frac{20}{3})+\frac{6}{3} By simplifying the second fraction.

=(\frac{26}{3})

So, QR=\frac{26}{3}

dalvyx [7]
Let she work for x hours as carpenter !
so earned money = 20x

and for blacksmith she must work for 30-x hours


so earned money = (30-x) ×25

so putting in eqn;

20x+25(30-x) = 690
so, x= 60/5 = 12

so she works for carpenter for 12 hrs and 30-12= 18 hrs for blacksmith !!.....answer !!
