If two triangles are similar, that means their side lengths are proportional.

Now we want to find side PQ, so let us set up some proportions:

              \frac{PQ}{QR} =\frac{JL}{LK}\\ \\\frac{x}{33} = \frac{20}{22} \\ 22x = 33 *20\\22x = 660\\x = 30\\\\

So x = 30.

Hope that helps!

Solve the simultaneous equations y=3x+2 and y=x+6
kogti [31]

Answer:

x=2

Step-by-step explanation:

y=3x+2

y=x+6

Since you're stating that, they both equal because equation is equated to equation 2 because of the Y.

Therefore, substitute into both equations as shown:

3x+2=x+6

3x-x=6-2  (bring 2 to the other side by subtracting 2 as well as x)

2x=4

2x/2=4/2  (dividing 2 on both sides to get rid off 2 in 2x)

x=2.

The 6 consecutive integers below add up to 447. x − 2 x − 1 x x + 1 x + 2 x + 3 what is the value of x ? f. 72 g. 73 h. 74 j. 75
IrinaVladis [17]
(x-2) + (x-1) + x + (x+1) + (x-2) + (x+3) = 447
6x + 3 = 447
6x = 447 - 3
6x = 444
x = 444/6
x = 74
