-15x - 3y = 3
-15x - 3(5x-1) = 3 [input y]
-15x - 15x - 3 = 3 [distribute 3 over 5x and -1]
-30x - 3 = 3 [combine like terms]
-30x = 6 [add 3 to eliminate the negative]
x =
[divide by -30 to get x alone]
x =
[reduce the fraction]
Hopefully this is helpful enough to get you to your answer
Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
If you would like to calculate <span>10÷5/8, you can do this using the following steps:
</span><span>10÷5/8 = (10/5)/8 = 2/8 = 1/4 = 0.25
The correct result would be 1/4 or 0.25.</span>
Decrease means minus or '-'
it is an operation because it opperates or does something to the numbers. it is like a verb
an integer is the thing being operated on. it is like the noun
