Answer:
x=-6
Step-by-step explanation:
1. Collect like terms [-15x] [+6x]
-15x+10+6x=64
-9x+10=64
2. Move constant [+10] to the right-hand side and change its sign
-9x+10=64
-9x=64-10
3. Subtract the numbers [64-10]
-9x=64-10
-9x=54
4. Divide both sides of the equation by -9
-9x/9=54/9
5. Solution
x=-6
Answer:
Step-by-step explanation:
If it is a Pythagorean Triple the hypotenuse and the legs of a right triangle will all be integer values where
c^2=a^2+b^2
In this case, this isn’t even a right triangle as
20^2+30^2=40^2
400+900=1600
1300!=1600
because 1300 does not equal 1600 this is not a Pythagorean Triple.
Answer:
3/2 OR 1 1/2
Step-by-step explanation:
Collect like terms, meaning combine both y's. You should have something like this afterwards.
6y = 9
Now that you have that divide the 6 on both sides so Y is by itself!
Your answer is now 3/2.
