Answer:
<h2>
John has $15 and Alex has $33</h2>
Step-by-step explanation:
a systems of equations can be made from the information on the problem
x+y=48
x=2y+3
since x= 2y+3 substitute 2y+3 in the firat equation to get:
(2y+3)+y=48 -> 3y+3=48 -> 3y=45 -> y=15
plug in 15 for y in the second equation to solve for x
x+15 =48 --> x=33
The quadratic formula is hard to type on this
3 (+ , -) (sqroot of 41)

Answer:
it is False
Step-by-step explanation:
Answer:
First, you get both of them with same denominator:
3/7 and 2/3 => 9/21 and 14/21, however, there are only 4 rational numbers between 9/21 and 14/21.
The solution is that you can raise the denominator 2 times:
9/21 and 14/21 => 18/42 and 28/42
Now you can select : 19/42, 20/42, 21/42, 22/42, 23/42. They are a group of 5 rational numbers you are looking for.
Option A is correct
assuming we use the Pythagorean theorem whose formula is c²= √a² + b²
C being the longest side, a=15 and b=20
c² = √15²+ 20²
c² = √625
c= 25
if you try this formula with the other options it shows it's not a right triangle
