Answer:
3x-13 I believe
Step-by-step explanation:
You multiply the 3 to the x and the 5. This would equal 3x-15+2
You would then add the -15 and the 2. This would be the answer 3x-13
Sorry if it is wrong
Im guessing 21 and 72 are the side lengths for the triangle?
Alright, so since it's a right triangle you can use the Pythagorean theorem or a^2+b^2=c^2
Since i cant see the picture, im going to use some general math <span>so i</span> can figure out if those two sides are the legs or if one of them is the hypotenuse
Alright
so im guessing the side we're trying to find is the hypotenuse
21^2+72^2=c^2
441+5184=c^2
5625=c^2
<span>√5625=c</span>
75=c
The answer is 75, hope i helped!
Answer:

Step-by-step explanation:
There are 6 values on a die, and we want 2 values. The fraction now is
. But, wait! We can simplify this fraction:
.
Side note:
I understand if you wanted just the
fraction and not simplified.
Let’s arrange the fist equation
x+y=12
2x+3y=29
Multiply equation 1 by 2
So it will be
2x+2y=24
Subtract eq 1 from eq 2
2x+3y=29
2x+2y=24
—————-
Y =5
Put value of y in eq 1
2x+2y=24
2x +10= 24
2x= 24-10
2x= 14
x=14/2
x=7
S.S= (7,5)
