Okay, I'm going to be adding more but what is 4/10 x 3?

Marat540 [252]

Answer:

6/5 or 1 1/5

6/5 is an improper fraction, so I didnt know if youd need an improper one or a proper one. They both are the same thing though :)

Step-by-step explanation:

4/10*3

They both need to be a fraction, and any number over 1 = that number. So,

4/10*3/1

4*3=12

10*1=10

12/10

Then, you have to simplify the fraction.

6/5 (bc 2 goes into 12 6 times and 2 goes into 10 5 times)

or 1 2/10= 1 1/5

Hope this helps. Plz give brainliest. Also, plz sub to Kgirl633 on yt.

Solve for x & y <br><br> plsssss, sorry.

Answer:

$\huge\boxed{x=29;\ y=51}$

Step-by-step explanation:

This is Isosceles triangle (look at the picture).

We know:

All triangles have internal angles that add up to 180°

Therefore:

$(x-2)+(x-2)+(4x+10)=180$

combine like terms:

$(x+x+4x)+(-2-2+10)=180\\\\6x+6=180\qquad|\text{subtract 6 from both sides}\\\\6x=174\qquad|\text{divide both sides by 6}\\\\x=29$

(x - 2)° and 3y° are supplementary angle (Two Angles are Supplementary when they add up to 180°).

Therefore:

$3y+(x-2)=180$

substitute x = 29 and solve for y:

$3y+(29-2)=180\\\\3y+27=180\qquad|\text{subtract 27 from both sides}\\\\3y=153\qquad|\text{divide both sides by 3}\\\\y=51$
