Andy maximal age= 13.3
Matt maximal age= 21.7
I will translate the problem into 2 equation where X is Andy's age and Y is Matt's age.
Y+5= 2X
Y= 2X-5
X+Y<35
From this equation, it is clear that you won't be able to find their age. But you can find maximal age of Andy and Matt by changing X+Y<35 into X+Y=35
Inserting the first equation to the second equation you will get:
X+Y=35
X+ (2X-5)=35
3X= 35+5=40
X=13.3
X+Y=35
13.3+Y=35
Y= 21.7

Step-by-step explanation:
Acute triangle : 0<x<90 degrees
right triangle : x=90 degrees
obtuse triangle :triangles that angles are bigger than 90 but smaller than 180 degrees
reflex angle:bigger than 180 but smaller than 360 degrees
Answer: 88
Step-by-step explanation:
17 +|-14-65|-8
17 + |-79| -8
17+79 -8
96-8 = 88
<h2>
Center is (7,-3) and radius is 8</h2>
Step-by-step explanation:
Equation of circle with (h,k) as center and radius r is given by,
(x-h)²+(y-k)² = r²
Here we need to find the radius and center of the circle given by the equation (x-7)²+(y+3)²=64
Changing equation to (x-h)²+(y-k)² = r² form
(x-7)²+(y+3)²=64
(x-7)²+(y-(-3))² = 8²
So, h = 7 , k = -3 and r = 8
Center is (7,-3) and radius is 8
