Answer:
403
Step-by-step explanation:
X=8+y
x+y=70
Rewrite the first equation to x-y=8
Copy the second equation x+y=70
Add the two equations and you get 2x=78
Therefore, x=39. Since this is the bigger number the smaller number(y) would have to be 31 because you subtract 8 from x which is 39. 39 is your answer.
Answer:
C
Step-by-step explanation:
Perimeter of a triangle is the sum of all the sides.
A triangle has 3 sides, so if we add up all the 3 sides lengths <em>(given as expressions here)</em> of the triangle, we will have the perimeter.
Perimeter =
<em>Now combining like terms we have:</em>
<em></em>
Answer choice C is the correct one.

Answer:
4.7
Step-by-step explanation:
The segment marked x connects the midpoints of the chord and the diameter, so is the unknown leg of a right triangle with hypotenuse 16/2=8 and leg 6.5.
The Pythagorean theorem tells you ...
x² + 6.5² = 8²
x = √(64 -42.25) ≈ 4.664 ≈ 4.7
