To set up an equation for this you can use a variable to represent your unknown (in this case the unknown is how long it will take to frame 54 houses)

We know that 3 houses can be framed in 1 week so you can represent the equation as 

3x=54 (3 being the amount of houses framed in 1 week, x being how many weeks it will take to frame 54 houses)

You can isolate X by dividing both sides by 3 (3x/3 = 54/3) which simplifies to 
x = 54/3

Help, in geometry please?<br><br>Thank you!

1) Draw the triangles JKL and J'K'L' in a same coordinate system.

When I did that, I realize the if you translate the triangle JKL 1 unit left and then you reflects the image across the x-axys you get the you get the triangle J'K'L'.

So, select the boxes in that same order:

      1) translation 1 unit left

      2) reflection across the x - axis.

2) The answer ot the second question is line r.

That is called the line of reflection because if you reflect the figures through it you will have the same figure.

Can someone help me thanks
algol [13]

Let x be the length of the third side.

Thus:

\mathsf{25^2=17^2+x^2}\\\\\mathsf{625=289+x^2}\\\\\mathsf{x^2=625-289}\\\\\mathsf{x^2=336}\\\\\mathsf{x=\sqrt{336}}\\\\\boxed{\mathsf{x=4\sqrt{21}}}

Alice's grandmothers age is a composite number between 70 and 80 and has a factor of 11 what is it
pshichka [43]

The factor of 11 is going to be 77 because you have to stay in between 70 to 80

and 7 times 11 is 77. It also has to be a number in the 11 timetables. It can't be 88 because we can't cross 80 so the factor is going to be 77.


Hope it helps
