Determine if the set of numbers create a Pythagorean triple. 2.1, 7.2, and 7.5
Minchanka [31]

Answer:

Yes, the set of numbers create a Pythagorean triple

Step-by-step explanation:

we know that

If a set of numbers create a Pythagorean triple, then the set of numbers must satisfy the Pythagorean Theorem

c^2=a^2+b^2

where

c is the greater side

a and b are the legs (perpendicular sides)

we have

c=7.5\\a=2.1\\b=7.2

substitute

7.5^2=2.1^2+7.2^2

56.25=4.41+51.84

56.25=56.25 ----> is true

therefore

Yes, the set of numbers create a Pythagorean triple

The greater of two numbers is 1 more than twice the smaller. Three times the greater exceeds 5 times the smaller by 10. Find the
earnstyle [38]
X<y
y is 1 more than 2 times the smaler
y=1+2 times x
y=1+2x

3 times y is bigger than 5 times x by 10
3y=5x+10
subsitute
y=1+2x
3(1+2x)=5x+10
3+6x=5x+10
subtract 3 from both sides
6x=5x+7
subtract 5x from both sides
x=7
subsitute
y=1+2x
y=1+2(7)
y=1+14
y=15

x=7
y=15
