Solve for x using cross multiplication

Mathematics
1 answer:
Sergio039 [100]4 years ago

\frac{x+4}{3} = \frac{x+6}{4}

I've attached a picture showing how to do the cross multiplication. If you look at that, you'll see that once you cross multiply you get:

3 (x+6) = 4 (x+4)

Then we use the distributive property:

3x + 18 = 4x + 16

Now we need to get all the x's on one side and all the numbers on the other. Start by subtracting 3x from both sides

3x + 18 -3x = 4x + 16 -3x

On the left side they cancel out:

18 = x + 16

Subtract 16 from both sides:

18 - 16 = x + 16 - 16

It cancels out on the right, ans you get:

2 = x

There's your answer :)

Zanzabum

Answer:

Rhombus

Step-by-step explanation:

This undoubtedly has to be a rhombus. When you look at other quadrilaterals for example and want to judge and or differentiate, we see that in the case of a square, the diagonals are equal to one another and they are not congruent. Same can be applied to that of a rectangle as well, it's diagonals aren't congruent, even if they appear perpendicular.

On the other hand, the diagonals of a rhombus is both perpendicular, and at the same time congruent. And thus, that's our answer

Paha777 [63]

Answer:

Ok, she walks 3 miles to and from the library.

So in total, she walks 3 miles two times, then in one week, she walks 2*3mi = 6miles.

She says that she walked about 300 miles in total.

We must see if 300 miles is a multiple of 6 miles.

300mi/6mi = 50.

This means that she would walk about 300 miles since she started counting if she went to the library and back home exactly 50 times (again, since she started counting).

And she does this once a week, then if she started counting 50 weeks ago, then it is possible,
