Answer:
The 3 numbers must be multiples of 3, 4, and 5
Step-by-step explanation:
Pythagorean Triples are numbers that you know will come out perfectly in the Pythagorean Theorem. But the easiest way to explain this is to show you an example.
Say you're given the numbers 12, 16, and 20.
They should be able to be divided by the same number and equal 3, 4, and 5.
In this case, the number is 4.
12/4=3
16/4=4
20/4=5
So, this is a 3-4-5 triangle, or a Pythagorean Triple.
Answer:
x = -10
Step-by-step explanation:
-2x - 10y = 20 (plug y=0)
-2x = 20
x = 20/-2
x = -10
Answer:
the probability of selecting a yellow is 4 out of 20
It would be $22.50, because if you buy a burger for $3 and you get it for a 5 day period which would be $15. And then if you buy a juice for $1.50 for 5 days would be $7.50. So you would add $15 and $7.50 would be $22.50 for the whole 5 days.
Answer: yes, she did made an error, a very big mistake.
Step-by-step explanation:
first, we have varieties of ways in which we can use to solve this, the most important thing is to stick to the mathematical rules of solving any equations.
using the most simpler method
-4x + 11 = 6x + 1
collect like ter
-4x -6x = 1 - 11
-10x = -10
divide bothside by -10
-10x/-10 = -10/-10
x=1
secondly, using the method she is intending to use, its more easier to subtract 6x from bothside
-4x + 11 = 6x +1
-6x -6x
_______________
-10x + 11 = 1
-10x = 1-11
-10x = -10
x = 1
or still we can doing it exactly as she did, but it will take us through a long way i.e by adding +6
-4x + 11 = 6x + 1
+6x +6x
_______________
2x +11 = 12x +1
2x-12x = 1-11
-10x=-10
x=1
