I’m pretty sure you cross multiply the numerator to have the same denominator than add. After than you will simply multiply the reciprocal (5) with the numerator than simplify again

First is to cross multiply and I get 35/35 + 15/35 and I get 50/35

ill simplify down to 10/7

Now we have to divide 10/7 by 5 so I multiply the reciprocal and my equation looks like 10(5) / 7

That gives me 50/7

Did you forget the /7?

Best thing to do with fractions is to get common denominator, if you have a fraction (a/b) and you add it to (c/d) you can add them if you make their denominators the same, by multiplying the (a/b) one by (d/d) (which is 1 and therefore allowed) and the (c/d) one by (b/b), then adding them together (da + bc)/(db)

I tried 50/7, and it was wrong. That was the first answer I came up with.

Ok idk what the answer is then

Do 5/5 + 3/7 first to get 10/7

Then do 10/7 * 1/5 to get 10/35 and then simplify to 2/7

You’re correct in the sense that you do 10/7 divided by 5, which can also be written as 5/1. But when you divide fractions, you have to flip the denominator and multiply that by the numerator. That means 10/7 *1/5 = 10/35 = 2/7

Oh I forgot to flip the denominator

I have a question about some geometry

I have a triangle and I know one angle measure is 70 degrees and that another angle is equal to 4a-4 and the other angle is blank how do i solve for 4

<:KekFull:802560939500503041> "how do you solve for 4?" it's 4

can you give us the question/diagram?

Er

I meant A lol

Ye, i usually don’t need help I just happened to miss the class

it's alright

the third angle is blank?

what is the triangle type?

I don’t understand the D@ and the d+the triangles angles

I just realized they’re congruent though

To solve would it be 4a-4=48?

Yes, I believe so.

@Seal

I got 13 for both

I set 5b-3 equal to 62

What’s an asa postulate?

@isoboto I think the top equation is wrong. 180-70-48 is not right. I think you'd use 62 instead of 48.

where would the 62 comes from 👀 180 - 48?

Well

You can assume the angle measure of the last angle

it's angle-side-angle

Idk what that means

oh, cuz you said it's congruent triangles. for congruent triangles, it means all the 3 sides & 3 angles are the same

What about sss

And sas
