Answer:
tv is 5 inches tall
Step-by-step explanation:
by using Pythagoras theorem
Hypotenuse (h)= 13
width/ base (b)=12
tall (p)= ?
h²=p² + b²
13²= p²+ 12²
169-144 = p²
25= p²
5²= p²
5=p
Answer:
It should be a dotted line through 10 on both the X and Y lines, with shading facing out from that. I've supplied a picture as well.

Answer:
3
Step-by-step explanation:
Let x represent the number. The problem statement tells you ...
2/3(3x +6) = 10
2x +4 = 10 . . . . . . use the distributive property
x +2 = 5 . . . . . . . . divide by 2
x = 3 . . . . . . . . . . .subtract 3
The number is 3.

<em>Comment on the solution</em>
The above shows an "alternative" solution method. The more usual way this might be done is ...
2(3x +6) = 30 . . . . . multiply by 3 to clear fractions
6x +12 = 30 . . . . . . . eliminate parentheses
6x = 18 . . . . . . . . . . . subtract 12
x = 3 . . . . . . . . . . . . divide by 6
D. 10
m<3 = 80 - (10) = 70
m<7 = 90 - (20) = 70
