PLEASE HELP ME SOLVE FOR X
jeka57 [31]

Looks like the labeled angle is bisected, in which case we can apply the angle bisector theorem. For this triangle, it says

\dfrac x3=\dfrac{x+2}{x+4}

Solve for x:

x(x+4)=3(x+2)

x^2+4x=3x+6

x^2+x-6=0

(x+3)(x-2)=0

Then either x=-3 or x=2, but since x is a length, it must be positive. So <em>x</em> = 2.

HUDSON HAS TO FILL A POT WITH 1 QUART OF WATER. ALL HE HAS IS 1/4 CUP MEASURING CUP. HOW MANY TIMES DOES HE HAVE TO FILL THE 1/4
Marta_Voda [28]
There are 4 cups in a quart.

So if Hudson has only a 1/4 measuring cup, this can be represented by the equation:

4/1/4, solving it we get: 4* 4 (dividing turns a fraction into its reciprocal)

So, 4*4=16

Hudson will have to fill the 1/4 measuring cup 16 times to get a quart.

I hope this helps!

What is 76/10 in a mixed number??
cestrela7 [59]
A mixed number is in the form x y/z while a improper fraction (76/10) is in the form y/z. We can separate the fraction into two parts. One is 70/10 which = 7 and the other is 6/10 which simplifies to 3/5. So, in order to express 76/10 as a mixed number we must express it as 7 3/5 or 7 6/10. 7 3/5 is equal to 7 6/10.

I hope this helped you!
